Ameloblastic fibroma (AF) is a rare benign tumor, with approximately 80% of AF cases occurring in patients below the age of 22 years. Notably, it is less frequent (16.9%) in patients aged ≤ 10 years. Most cases of AF occur in the mandible, with only a few occurrences in the maxilla. Herein, we report a case of AF in the maxilla of an 8-year-old child. In the present case, AF was suggested to have impaired the development of permanent teeth. Regular checkups, including radiographic examinations starting in childhood, may facilitate early detection of lesions in the maxillofacial region. [ABSTRACT FROM AUTHOR]

Aim Methodology Results Conclusions To assess Spanish dentists' management preferences for deep caries removal and exposed pulps in permanent teeth.A web‐based open and anonymous survey was distributed by social media and a specific website for this project amongst dentists practicing in Spain. The questionnaire comprised 40 questions, divided into five sections: (1) demographic data and professional activity; (2) carious tissue removal; (3) decision‐making regarding pulp exposure; (4) direct pulp capping and (5) pulpotomy procedures in permanent teeth. Results were descriptively analysed. Logistic regression (95% CI) analyses and X2 tests were carried out.A total of 538 responses were received. Half the respondents (53.7%) preferred to perform complete caries excavation for shallow and moderate carious dentin lesions, and selective excavation to firm dentin for deep lesions (57.8%). Selective removal to soft dentin and stepwise removal were much less indicated (15.4% and 10.9%, respectively). Exposed pulps in asymptomatic teeth were treated by direct pulp capping (over 80%), decreasing in the presence of reversible pulpitis symptoms (57.1%). If irreversible pulpitis was diagnosed, a pulpectomy would be performed by 53.5% and 89.9% of the respondents in, respectively, immature and mature teeth. Pulpotomy was performed routinely only by 26.4% of the clinicians. Patients' attitudes and priorities were the most relevant criteria when performing direct pulp capping and pulpotomy, together with the history of pain and the presence of bleeding. Regarding the clinical procedure, dry cotton was preferred to obtain haemostasis and Biodentine was the material of election.Caries removal preferences and management of pulp exposure by dentists practicing in Spain deviated from vital pulp treatment guidelines, mainly regarding indications and case selection. Pulp exposure was managed by direct pulp capping in asymptomatic cases, whilst immature permanent molars favoured the indication of pulpotomy when pulpitis was diagnosed. Most clinicians used hydraulic calcium silicate cement, specifically Biodentine, to perform vital pulp treatments. Postgraduate formation and continuing education in caries lesions management and vital pulp treatments were consistently related to more conservative and updated decisions. [ABSTRACT FROM AUTHOR]

Vital pulp therapy aims to preserve the vitality of dental pulp exposed due to caries, trauma, or restorative procedures. The aim of the present review was to evaluate the clinical, radiographic, and histological outcomes of different calcium silicate-based cements used in vital pulp therapy for both primary and permanent teeth. The review included 40 randomized controlled trials from a search across PubMed, LILACS, and the Cochrane Collaboration, as well as manual searches and author inquiries according to specific inclusion and exclusion criteria. A critical assessment of studies was conducted, and after data extraction the results were submitted to a quantitative statistical analysis using meta-analysis. The studies, involving 1701 patients and 3168 teeth, compared a total of 18 different calcium silicate-based cements in both dentitions. The qualitative synthesis showed no significant differences in short-term outcomes (up to 6 months) between different calcium silicate-based cements in primary teeth. ProRoot MTA and Biodentine showed similar clinical and radiographic success rates at 6 and 12 months. In permanent teeth, although the global results appeared to be well balanced, ProRoot MTA generally seemed to perform better than other calcium silicate-based cements except for Biodentine, which had comparable or superior results at 6 months. Meta-analyses for selected comparisons showed no significant differences in clinical and radiographic outcomes between ProRoot MTA and Biodentine over follow-up periods. The present review highlights the need for standardized definitions of success and follow-up periods in future studies to better guide clinical decisions. Despite the introduction of new calcium silicate-based cements aiming to address limitations of the original MTA. ProRoot MTA and Biodentine remain the most used and reliable materials for vital pulp therapy, although the results did not deviate that much from the other calcium silicate-based cements. Further long-term studies are required to establish the optimal CSC for each clinical scenario in both dentitions. [ABSTRACT FROM AUTHOR]

Background: For the elderly population, efforts are made to simplify the restorative procedure while maintaining good clinical performance. Glass ionomer (GI) cements are showing signs to fulfill many of these qualities. With their new properties and ease of use, they can be developed further to become a useful group of materials to overcome the problems of elderly patients. Aim: The aim of the study was to evaluate the clinical performance of zirconia-reinforced versus conventional viscous GI restorations in Class I cavities of geriatric patients. Setting and Design: The study design was in vivo randomized clinical trial, parallel-arms, allocation ratio: 1:1. Subjects and Methods: A total of 28 Class I carious lesions in 21 geriatric patients were restored randomly either by zirconomer-improved or Ketac Molar Quick Aplicap (n = 14) each. Restorations were evaluated for 1 year by modified USPHS criteria. Statistical Analysis: Data were analyzed with the Chi-square test and Cochran’s Q-test. Survival rate was analyzed using the Kaplan–Meier and log-rank test. Results: Twenty-four restorations were evaluated in 19 patients with a recall rate of 85.7% at 12 months. Significant differences were found in marginal integrity and marginal discoloration within both restorative materials between different time intervals (P < 0.05). However, none of the materials were superior to another regarding all assessed criteria. Conclusions: Both zirconia-reinforced GI and conventional highly viscous GI have acceptable clinical performance.

The purpose of this systematic review and meta‐analysis is to conduct a comparative evaluation of partial and full pulpotomy techniques in cariously exposed teeth with symptoms indicative of symptomatic irreversible pulpitis. Databases such as PubMed, EMBASE, Cochrane, and Web of Science were searched. Studies evaluating and/or comparing clinical and/or radiographic success of partial and full pulpotomy in teeth diagnosed with irreversible pulpitis with a minimum of 12 months follow‐up were included. The risk of bias (ROB) tool was used for the assessment of ROB. A meta‐analysis was conducted to compare the healing outcome of partial and full pulpotomy. Three studies fulfilled the inclusion criteria, there was a low risk of bias in each of the five domains. Full pulpotomy had a higher success rate than partial pulpotomy, according to meta‐analysis, but the difference was not statistically significant. [ABSTRACT FROM AUTHOR]

Aim/Objective: This umbrella review of systematic reviews aims to summarize the available data regarding both success and survival rates of tooth autotransplantation, in addition to analyzing the risk factors that are connected to those rates. Methods: This umbrella review was performed according to the evaluation of various meta-analyses and systematic reviews following AMSTAR2 guidelines. A systematic search of literature on PubMed, Scopus, MEDLINE, EMBASE, and the Cochrane Database. Six systematic reviews were included. Explicit inclusion and exclusion criteria were applied. It is registered in PROSPERO under the registration number (CRD-42023415623). Results: The studies reviewed were written from 2014 to 2018, which extracted the information from various studies spanning from 1968 to 2014. According to the selected studies regarding autotransplanted teeth in humans, they showed the following: A survival rate overall of 87.39% and a success rate overall of 90.29%. These factors were the most common in relation to the success of the autotransplanted teeth: age, gender, and stage of root development. On the other hand, common unfavorable results linked to the transplanted teeth in these studies were failure, ankylosis, and internal root resorption, followed by extraction and hypermobility. Conclusions: The wide body of evidence gathered illustrates that autotransplantation is an operation that dispenses high rates of survival and success. Furthermore, risk factors like root development stage, recipient site, and donor tooth type established a remarkable association with the negative outcomes of the procedure. For successful tooth autotransplantation, patient selection is crucial. Younger patients and those with donor teeth at an optimal stage of root development typically experience better outcomes. Preoperative planning should include comprehensive evaluations and advanced imaging techniques to accurately assess both the donor tooth and the recipient site. Nonetheless, on account of heterogeneity and the quality of the studies included in this investigation, caution should be taken when interpreting the mentioned results. [ABSTRACT FROM AUTHOR]

This paper presents a retrospective analysis of postmortem computed tomography (PMCT) scans of secondary ossification centers in the medial clavicular epiphysis, iliac crest apophysis, proximal humeral epiphysis, distal femoral epiphysis, proximal tibial epiphysis, and distal tibial epiphysis. At the same time, we analyzed PMCT scans of the maxillary and mandibular incisors, canines, premolars, and molars. We assessed 203 corpses, whose age ranged from 2 to 30 years, including 156 males and 47 females. The purpose of our study was to compare the processes of secondary ossification center fusion and permanent tooth maturation. Our research hypothesis was that certain stages of skeletal and dental maturation occur along consistent timelines that can be related to the chronological age. Secondary ossification center fusion was evaluated based on Kreitner and also McKern and Steward's classifications. The process of permanent tooth maturation was evaluated with Demirjian's method. Spearman's correlation coefficients (Rho) were positive in all analyses, which indicates that epiphyseal fusion progresses with age. The strongest relationship between the age and the stages of ossification was observed in the proximal tibial epiphysis (p < 0.001; Rho = 0.93) in females and in the medial clavicular epiphysis (p < 0.001; Rho = 0.77) in males. Studies show the importance of concomitant analysis of skeletal and dental maturation with a subsequent comparison of the results to achieve a greater precision in age estimation. A comparison of the results obtained in the study population of Polish children, adolescents, and young adults with the results of other studies in populations of similar ages showed a number of similarities in the time windows of dental and skeletal maturation. These similarities may help in age estimation. [ABSTRACT FROM AUTHOR]

Purpose: This umbrella review aimed to critically appraise the evidence published in systematic reviews (SRs) on the clinical effectiveness of sealants compared with each other/the non-use in primary/permanent teeth of children and adolescents with at least 12-month follow-up. Methods: A systematic literature search on 4 electronic databases was conducted up to January 18th, 2023. Following handsearching, two review authors independently screened retrieved articles, extracted data, and assessed the risk of bias (RoB) using the risk of bias in systematic reviews (ROBIS) tool. Based on a citation matrix, the overlap was interpreted by the corrected covered area (CCA). Results: Of 239 retrieved records, 7 SRs met the eligibility criteria with a moderate overlap among them (CCA = 7.4%). For primary molars, in 1120 1.5- to 8-year-old children, data on the clinical effectiveness of sealants were inconclusive. For permanent molars, 3 SRs found a significant caries risk reduction for sealants versus non-use (≤ 36-month follow-up). There was insufficient evidence to proof superiority of sealants over fluoride varnish for caries prevention (3 SRs), and to rank sealant materials according to the best clinical effectiveness in permanent molars. One study was rated at low and 6 at high RoB, which did not allow for a valid quantitative synthesis. Conclusion: Considering the limitations of this umbrella review, sealants are more effective for caries prevention in children's permanent molars compared to no treatment. Future well-implemented RCTs are needed to draw reliable conclusions on the clinical effectiveness of sealants in primary and permanent teeth of children and adolescents. [ABSTRACT FROM AUTHOR]

ObjectiveThe aim of this study was to investigate the pattern and distribution of traumatic injuries to primary and permanent anterior teeth in 2–14-year-old pediatric dental patients in AlHassa region of Saudi Arabia. MethodsThe study sample consisted of pediatric dental patients visiting the university dental complex seeking treatment for traumatic dental injuries (TDIs) during the period from February 2022 to April 2023. Data were collected by means of interviewing the children and/or parents regarding the history of trauma and clinical examination for evidence of dental trauma to primary and permanent teeth. ResultsA total of 122 children (184 teeth) including 78 (63.9%) boys and 44 (36.1%) girls sustained traumatic injuries to their teeth. The most common reason for dental trauma was falls, and maxillary right central incisor was the most frequently affected permanent teeth. Enamel-dentine fractures in permanent teeth and luxation injuries among primary teeth were predominantly noted. Majority of the injuries (47.5%) have been found to have not received timely attention for treatment. ConclusionsEarly treatment of dental trauma should be emphasized, and preventive strategies targeted at parents and teachers at the community level are needed to promote and reduce the burden of TDIs.

Background: There is an increased tendency towards adopting minimally invasive interventions in dentistry, supported by advancement in materials and techniques. However, the decision‐making process in choosing conservative or invasive treatments is influenced by several factors, particularly in permanent teeth with irreversible pulpitis. Objectives: The objective of the study was to systematically review the literature regarding factors that influence decision‐making for vital pulp therapy (VPT) as definitive treatment option in permanent mature teeth diagnosed with irreversible pulpitis. Methods: Two independent reviewers searched five electronic databases (PubMed, Embase, Web of Science, Scopus and Cochrane Library). Grey literature was searched through Google Scholar and contact with experts. Defined search keys were applied, and all peer‐reviewed literature published with no language nor publication date limits were included. The All studies investigating the factors influencing treatment decision‐making in mature permanent teeth with irreversible pulpitis were included. The quality of included studies was assessed by two independent reviewers using the Joanna Briggs Institute quality assessment tool. Results: Six articles were included in the review. All included studies used questionnaires to characterize clinician preferences and attitudes in choosing treatment options for mature permanent teeth with irreversible pulpitis. The available evidence suggests that dentist‐related factors have a significant influence on the chosen treatment in teeth with irreversible pulpitis, with speciality training and years of experience influencing the choice of VPT over other treatment options. COVID‐19 reportedly swayed the dentists' decision to favour VPT. Only one article studied the influence of patient‐related factors, such as age and presence of spontaneous pain on decision‐making. Of note, a history of cardiovascular disease moved dentists towards prescribing VPT. Discussion: Collectively, the included studies demonstrated an overriding influence of dentist‐related factors on choosing among treatment options for painful teeth diagnosed with irreversible pulpitis. Patient‐related factors were acknowledged but there are also potential factors such as socio‐economic constraints that were not included in the component studies. Conclusion: In teeth with irreversible pulpitis clinicians educational background influence the decision towards a specific treatment option. Further data, preferably derived from clinical records, is necessary in future investigations to explore the effect of other important factors related to both dentists and patients. Registration: PROSPERO database (CRD42022339653). [ABSTRACT FROM AUTHOR]

Odontogenic keratocysts (OKCs) are one of the most frequently encountered cystic diseases of the jaw in clinical practice. Although OKC has been reported as a manifestation of nevoid basal cell carcinoma syndrome (Gorlin syndrome) in many pediatric patients, there have been few reports of OKC occurring in isolation. Herein, we report the case of a relatively large OKC in the mandibular body of a 7‐year‐old girl who was treated conservatively using cystectomy and open wound surgery, and the permanent teeth were unaffected. Regular check‐ups, including radiographic examinations, starting in childhood may contribute to the early detection of lesions in the maxillofacial region. [ABSTRACT FROM AUTHOR]

Enamel hypoplasia (EH) is a qualitative defect, and it can have a significant impact on oral health. The aim of this study was to evaluate the prevalence of enamel hypoplasia in urban area in Albania. Methodology: In total, 234 children of both sexes aged 8–12 years old were randomly selected in five schools in Tirana, Albania. They underwent an intra-oral examination. Diagnostic criteria were in accordance with a European meeting on MIH held in Athens, 2003, and the FDI. Medical history was retrieved using questionnaires, and data obtained from clinical examination were recorded. Results: The prevalence of enamel hypoplasia was 12.8%. The most commonly occurring enamel hypoplasia was the mild type (58.62%). The mandibular first molar showed the highest prevalence of enamel hypoplasia (19.5%), and the maxillary canines and premolars were the least affected (2.3%). In this study, medical story did not have a significant effect on enamel hypoplasia. Conclusions: The prevalence of enamel hypoplasia remains high at 12.8%. Interestingly, the features of enamel hypoplasia were consistent across both sexes, with no correlation found between them. The predominant occurrence of mild enamel hypoplasia underscores the importance of implementing oral hygiene strategies in schools to mitigate its progression. [ABSTRACT FROM AUTHOR]

Aim: The present retrospective cohort study aimed to evaluate luxated permanent teeth for pulp prognosis and risk factors. Methodology: Case records and radiographs of 224 patients, involving 427 luxated permanent teeth, referred for treatment at the Dental Trauma Center–School of Dentistry, Universidade Federal de Minas Gerais, (DTC-SD–UFMG) from 2014 to 2022, were assessed for pulp prognosis classified as vitality, necrosis and pulp canal obliteration (PCO). A competing risk survival analysis estimated the hazards of the three outcomes, and the effect of demographic, clinical and treatment variables was tested using a cause specific Cox regression model. Results: Pulp vitality was found in163 teeth (38.2%), pulp necrosis in 120 teeth (28.1%) and 55 teeth (12.9%) developed PCO. Pulp vitality decreased in the presence of concomitant crown fractures (HR 0.38 95% CI [0.2–0.8] p = 0.006). The risk of pulp necrosis (HR 0.62 95% CI [0.4–0.96] p = 0.03) was lower in cases with open apices but increased with concomitant crown fractures (HR 4.0 95% CI [2.6–6.1] p = 0.001) and intrusions (HR 2.3 95% CI [1.2–4.1] p = 0.007). Lateral or extrusive luxations (HR 3.0 95% CI [1.3–6.9] p = 0.001) and open apices (HR 2.4 95% CI [1.2–4.7] p = 0.01) showed higher rates of PCO. Conclusion: Type of luxation, the diameter of the apical foramen, and the presence of concomitant crown fractures were main determinants of pulp prognosis after luxation injuries in permanent teeth. Clinical relevance: Pulp prognosis after tooth luxation is dependent on the presence and direction of tooth displacement together with infection control. Clinical trial registration: Not applicable.

AimThe first comprehensive chart on dental development was published 75 years ago based on Caucasian children and this has been used as a standard dental chart to date. Few population specific charts have been developed recently and updated dental charts on modern subjects can provide more information on dental development patterns. This study aims to construct a comprehensive dental atlas for modern Chinese children and young adults to assist in clinical, forensic, and public health applications.MethodsThe study sample comprised of 2,306 subjects, age ranging from 2 to 24 years belonging to Chinese ethnicity. Dental formation and eruption of permanent teeth and resorption of primary teeth were analyzed separately for females and males. For each age range, the number of teeth (n), and the stage of development was calculated for first (Q1), second (Q2) and third quartiles (Q3). Similar analysis was performed for the position of permanent teeth and the resorption of primary teeth. To determine the variations between the sex, Mann-Whitney U-test was conducted by comparing the median (Q2) stages.ResultsVariations in dental formation and eruption of permanent teeth and resorption of primary teeth were observed between maxillary and mandibular dentitions and between the sex, however the difference was not statistically significant (p = 0.535 to p = 1.000). The dental atlas was presented separately for Chinese females and males.ConclusionThis atlas on modern Chinese population serves as a practical tool to assist in clinical diagnosis and treatment planning, in forensic investigations as well as indicators of developments in public health.

Background: The aim of this clinical study was to compare the occlusal caries detection (OCD) performance of the intraoral scanners (IOSs) Trios 4 (TIO, 3Shape) and Emerald S (EME, Planmeca) and the Diagnocam (DIA, KaVo) with the established visual (WHO) examination (VIS, reference method). Methods: Between 08/2022 and 02/2023, 60 children (mean age 9.6 ± 2.5 years) were examined as part of their regular dental checkups. OCD was performed at the tooth level, separately for primary and permanent unrestored teeth. Furthermore, two thresholds were analyzed: sound versus overall caries (pooled data of enamel and dentin caries, TH1) and pooled data of sound and enamel caries versus dentin caries (TH2). Results: The best agreement with the reference method (reliability) in both dentitions was obtained for DIA (ĸ = 0.829/ĸ = 0.846; primary/permanent teeth), followed by EME (ĸ = 0.827/ĸ = 0.837) and TIO (ĸ = 0.714/ĸ = 0.680). Similar results were shown for the diagnostic quality (sensitivity, specificity and area under the curve of the receiver operating characteristic curve), with higher values for TH1 than for TH2. Both IOSs and the DIA showed worse results than the reference method VIS. Conclusions: Currently, IOS should be used as an additional caries detection tool, especially for visualization, and cannot be recommended as a basic tool for diagnosis or invasive/noninvasive therapy decisions in OCD.

The aim of this umbrella review was to evaluate the longevity of glass ionomer cement (GIC) as a restorative material for primary and permanent teeth. Research in the literature was conducted in three databases (MedLine/PubMed, Web of Science, and Scopus). The inclusion criteria were: (1) to be a systematic review of clinical trials that (2) evaluated the clinical longevity of GICs as a restorative material in primary and/or permanent teeth; the exclusion criteria were: (1) not being a systematic review of clinical trials; (2) not evaluating longevity/clinical performance of GICs as a restorative material; and (3) studies of dental restorative materials in teeth with enamel alterations, root caries, and non-carious cervical lesions. Twenty-four eligible articles were identified, and 13 were included. The follow-up periods ranged from 6 months to 6 years. Different types of GICs were evaluated in the included studies: resin-modified glass ionomer cement (RMGIC), compomers, and low- and high-viscosity glass ionomer cement. Some studies compared amalgam and composite resins to GICs regarding longevity/clinical performance. Analyzing the AMSTAR-2 results, none of the articles had positive criteria in all the evaluated requisites, and none of the articles had an a priori design. The criteria considered for the analysis of the risk of bias of the included studies were evaluated through the ROBIS tool, and the results of this analysis showed that seven studies had a low risk of bias; three studies had positive results in all criteria except for one criterion of unclear risk; and two studies showed a high risk of bias. GRADE tool was used to determine the quality of evidence; for the degree of recommendations, all studies were classified as Class II, meaning there was still conflicting evidence on the clinical performance/longevity of GICs and their recommendations compared to other materials. The level of evidence was classified as Level B, meaning that the data were obtained from less robust meta-analyses and single randomized clinical trials. To the best of our knowledge, this is the first umbrella review approaching GIC in permanent teeth. GICs are a good choice in both dentitions, but primary dentition presents more evidence, especially regarding the atraumatic restorative treatment (ART) technique. Within the limitation of this study, it is still questionable if GIC is a good restorative material in the medium/long term for permanent and primary dentition. Many of the included studies presented a high risk of bias and low quality. The techniques, type of GIC, type of cavity, and operator experience highly influence clinical performance. Thus, clinical decision-making should be based on the dental practitioner's ability, each case analysis, and the patient's wishes. More evidence is needed to determine which is the best material for definitive restorations in permanent and primary dentition. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical efficacy of three materials, mineral trioxide agglomerate（MTA), i Root BP Plus（i RooT), and calcium hydroxide（Ca(OH)2), in the live pulpotomy of young permanent teeth. Methods: Sixty patients（60 affected teeth）requiring vivipectomy of young permanent teeth were randomly divided into three groups according to the materials used: the MTA group, the i RooT group and the Ca(OH)2 group, with 20 patients（20 affected teeth） in each group. The success rate of the procedure, the incidence of dentin bridge formation and tooth discoloration, root canal wall thickness, tooth function and aesthetics, and serum matrix metalloproteinase-3（MMP-3） and interleukin-8（IL-8） levels were compared between the three groups at 3 and 6 months after surgery. Results:（1） The clinical treatment success rate was different among the three groups at 6 months postoperatively only（P＜0. 05); （2） The postoperative dentin bridge formation rate was lower in the Ca(OH)2 group than in the other two groups（P＜0. 05), while the incidence of tooth discoloration was lower in the MTA group（P＜0. 05） and higher than in the i RooT group（P＜0. 05). （3） The root canal wall thickness increased in all three groups after treatment compared with that before treatment, and the increase in root canal wall thickness in the Ca(OH)2 group was lower than that in the MTA and i RooT groups after treatment（P＜0. 05). （4） The dental comfort function, fixed function and masticatory function scores were significantly lower in the Ca(OH)2 group than in the MTA and i RooT groups at 6 months postoperatively（P＜0. 05), while the dental esthetics scores were lower in the i RooT group（P＜0. 05） and higher than in the MTA group（P＜0. 05). （5）Serum MMP-3 and IL-8 were lower in all three groups 6 months after surgery than before surgery（P＜0. 05), and the serum MMP-3 and IL-8 levels were higher in the MTA group than in the i RooT group（P＜0. 05） and lower in the CaOH group（P＜0. 05). Conclusion: Both i Root BP Plus and MTA materials have high long-term success rates for vivisection of young permanent teeth, but the MTA material has a high rate of long-term tooth discoloration and thus affects the aesthetics of the teeth.

Background: Teeth emergence is ordinal, chronological, and age-specific.1,3 Most of the time, the permanent teeth start erupting at the age of 6 years and complete the process by the age of 12 years. The objective of this study were to determine the time and sequence of eruption of permanent teeth of the four ethnic groups of Pakistan and compare them with the body fatness. Materials & Methods: This study was conducted in four cities of Pakistan (Karachi, Larkana, Peshawar and Quetta) from January 2022 to March 2023 to determine the time and sequence of eruption of permanent teeth of Pakistani children. Systematic cluster random sampling was applied to choose the participants. A total of 8787 children with at least one 'just erupted tooth' were collected from 163 schools in the above-mentioned cities. Each selected child was examined under a bright light in a sitting position and each tooth was recorded as either unerupted, just erupted, or erupted. Height and weight were measured using a digital scale without the shoe. The age of the child was taken from the schools' register. A questionnaire containing demographic information and some dietary habits was completed. A total of 8550 cases were collected and analyzed. Kruskal-Wallis non-parametric ANOVA, Tukey/Dunnett's T3 postHoc, and chi-square tests were applied for statistical analysis. Results: Out of 8550 children, 4526 (52.9%) were males. The percentage of underweight, normal, overweight, and obese children were 4.2%, 78.2%, 11.8%, and 5.8% respectively. Overweight and obese children were significantly higher than the internationally assigned percentage in those categories. Most of the teeth in central incisors, lateral incisors, and canines were erupted between the ages of 6-7 years, 7-8 years, and 9-11 years, respectively. Most of the posterior teeth erupted between 9-10 years (first pre-molars), 9-11 years (second premolars), 5-7 years (first molars), and 10-12 years (second molars). The sequence of the eruption was seen as Maxillary: FM, CI, LI, FPM, SPM, C, SM; Mandibular: FM, CI, LI, C, FPM, SPM, SM. Children of Quetta and Karachi showed late eruption as compared to children of Larkana and Peshawar. Mean values of overweight or obese children showed lower mean values than underweight and normal children. Conclusions: This multi-center study showed that the children of Karachi were exposed to the late eruption in most of the teeth as compared to children of Larkana, Quetta, and Peshawar. Furthermore, except for the first molars, all other teeth showed early eruption for overweight and obese children as compared to underweight and normal-weight children. This trend is comparable to the international findings. [ABSTRACT FROM AUTHOR]

Talon cusp is a rare dental anomaly involving the projection of a cusp from an anterior tooth, whereas fusion is another dental anomaly involving the joining of two teeth. This case displays a unique combination of both dental anomalies. An 8-year-old healthy Malay girl came to the pediatric dental clinic for her regular dental check-up. The intra-oral examination revealed the fused appearance of teeth 31, 32, and 41, 42 anterior mandibular teeth and the presence of talon cusps on the lingual surface of the fused teeth 41 and 42. A fissure sealant was placed in the fused area as a preventive measure. Thorough clinical and radiographic examination, early diagnosis, and proper treatment are important to prevent any future dental complications that may be associated with these rare anomalies.

Objectives: The objective of this study was to determine the time and sequence of emergence of permanent teeth of Baluchi children and compare them with other national and international reported data. Furthermore, to find out the effect of gender (male/female) type of schools (private/public); and relationship with height, weight, and body mass index of the children at the time of emergence. Methods: Systematic cluster random sampling procedure was used for sample selection. Two dentists along with 2 assistants visited 25 selected schools for data collection. Children with 'just erupted tooth' were selected for data collection. One thousand two hundred and sixty-seven selected children were examined. The selected children were examined for the status of emergence (not erupted, just erupted and erupted) in each tooth. Height and weight were measured and questions regarding food items usually consume in their families were recorded. Two independent samples 't' test, Pearson and partial corrections were used for comparisons and correlations. Results: Male children showed significant higher values of height, weight, and BMI as compared to the female children. Right 1st molars (#16 and #46) showed the lowest mean values of 5.5 and 5.6 years in upper and lower jaws, respectively. 2nd molars (#17 and #37) showed maximum mean values of 12.4 and 12.1 years in upper and lower jaws, respectively. Most of the mean values of male children were higher or equal to the female children. Most of the teeth showed higher values for private schools as compared to public schools. But none of above-mentioned differences were statistically significant. Twenty-two teeth showed significant correlation between emergence time and height of the children, while only 17 teeth showed significant correlation with weight. Conclusion: Mean eruption time of this study was higher than other national studies, but almost the same as other countries data. The eruption time of female children were insignificantly earlier than male children, which do not agree with other American, European African children. Time of emergence was delayed with increasing height, irrespective of the heavy or lightweight children. However, emergence time delayed with weight, if the child was also tall, but has no relationship with weight if the child is short [ABSTRACT FROM AUTHOR]

IntroductionEarly permanent dental caries can pose a serious threat to oral health in the coming years. This study aimed to investigate the key factors influencing early dental caries in permanent teeth among first-grade Iranian children.MethodsA cross-sectional study involving 778 randomly selected first-grade children from public schools in Tehran, Iran, was conducted between November 2017 and January 2018. The oral health of the children, evaluated by two trained dentists, was recorded based on the DMFT index. Information on maternal education, gender, dmft index, brushing frequency, dental visits, flossing, and sweet consumption was also collected. The Random Forest method was employed to identify factors associated with early permanent dental caries, and its performance was compared with logistic regression using the Area Under the Curve (AUC) index.ResultsLogistic regression, represented by odds ratios (OR), revealed a significant association between early permanent dental caries and dmft index [OR = 1.13, 95% CI (1.07, 1.20), p-value

Introduction: Obesity and dental caries are diseases that have a strong social impact. Being overweight and obesity during childhood are a risk factor for cardiovascular, respiratory, skeletal diseases and other health problems in both children and adults. Aim: The aim of the study is to estimate the relationship between tooth eruption, tooth pathology and BMI in 7-8 year old Bulgarian children. Methods and Material: The present study observed 187 individuals. Oral and dental status were examined. The height was measured in a standing position with an anthropometer, weight was measured with an electric scale to the nearest 0.1 kg, and Body Mass Index (BMI) was calculated. The data was analyzed with the Statistical Package for Social Sciences (SPSS) version 16. The differences were considered statistically significant at p

The issue of improving dental care protocols for children with multiple (decompensated) and complicated caries of permanent teeth, their full rehabilitation is particularly relevant, especially in periods of social cataclysms (the COVID-19 pandemic, martial law, etc.). The purpose of this study was an assessment of the dental caries experience, analysis of modern approaches to diagnosis, treatment, prevention and rehabilitation of complicated caries of permanent teeth among children in Kyiv. The material of the study was data from medical histories of 236 children aged 7-18 years. During the analysis of the obtained data, the dental caries experience, % of cases of toothache complaints and part of the need for replacement or correction of restorations after the treatment of complicated caries were calculated. The prevalence of caries of permanent teeth among 7-18-year-old children (n=236) in the period 2020-2023 was 42-95%, the dental caries experience – 1.73-6.4, the frequency of diagnosis of complicated caries – 4.8-37,1%, the prevalence of toothache – 31%, the part of the need for replacement of restorations after treatment of complicated caries – 62%. The obtained indicators confirm the absence of a downward trend compared to similar data for more than 15 years of observation. Diagnosis, treatment and full rehabilitation of complicated caries of permanent teeth in children is complex, multi-stage and requires the practical experience and patience of a dentist and the usage of the most modern materials and technologies. To date, there are no clear scientifically based protocols for the restoration of permanent teeth, in particular with incomplete root formation, after endodontic treatment. The usage of modern technologies of orthopedic dentistry and materials science (3D scanner, 3D printer, T-scan, polymers) will allow to significantly improve the quality of comprehensive treatment and rehabilitation of children with complications of caries of permanent teeth.

Vital pulp therapy aims to preserve the vitality of dental pulp exposed due to caries, trauma, or restorative procedures. The aim of the present review was to evaluate the clinical, radiographic, and histological outcomes of different calcium silicate-based cements used in vital pulp therapy for both primary and permanent teeth. The review included 40 randomized controlled trials from a search across PubMed, LILACS, and the Cochrane Collaboration, as well as manual searches and author inquiries according to specific inclusion and exclusion criteria. A critical assessment of studies was conducted, and after data extraction the results were submitted to a quantitative statistical analysis using meta-analysis. The studies, involving 1701 patients and 3168 teeth, compared a total of 18 different calcium silicate-based cements in both dentitions. The qualitative synthesis showed no significant differences in short-term outcomes (up to 6 months) between different calcium silicate-based cements in primary teeth. ProRoot MTA and Biodentine showed similar clinical and radiographic success rates at 6 and 12 months. In permanent teeth, although the global results appeared to be well balanced, ProRoot MTA generally seemed to perform better than other calcium silicate-based cements except for Biodentine, which had comparable or superior results at 6 months. Meta-analyses for selected comparisons showed no significant differences in clinical and radiographic outcomes between ProRoot MTA and Biodentine over follow-up periods. The present review highlights the need for standardized definitions of success and follow-up periods in future studies to better guide clinical decisions. Despite the introduction of new calcium silicate-based cements aiming to address limitations of the original MTA. ProRoot MTA and Biodentine remain the most used and reliable materials for vital pulp therapy, although the results did not deviate that much from the other calcium silicate-based cements. Further long-term studies are required to establish the optimal CSC for each clinical scenario in both dentitions.

Background: The results of vital pulp treatments in permanent teeth have been encouraging. Currently, pulpotomy treatment for permanent teeth primarily utilizes mineral trioxide aggregate (MTA) as the dressing material, followed by calcium hydroxide. While other calcium‐silicate‐based cements have been suggested for pulpotomy, there is a limited number of studies evaluating their long‐term effectiveness. Objectives: The objective of this systematic review and meta‐analysis was to evaluate the success rate of pulpotomies performed on permanent teeth, comparing the use of ProRoot MTA with that of calcium hydroxide and other bioceramic materials. Methods: A comprehensive search was conducted in several electronic databases, including PubMed, Cochrane Library, Scopus, Web of Science, Embase and Science Direct until December 2022. The search was guided by PICOS criteria, including only randomized clinical trials (RCTs) that evaluated the success rate of pulpotomy treatments in permanent teeth using ProRoot MTA in comparison to calcium hydroxide and other bioceramic materials. The quality of the included studies was assessed using the RoB‐2 tool to evaluate the risk of bias, and relevant data were extracted and analysed in RevMan software 5.3 using fixed‐effect models. The GRADE tool was used to determine the overall quality of evidence. Results: The initial search retrieved 1072 studies and, after eliminating duplicates, 677 studies were screened and 28 studies were considered for eligibility. In the final selection process, 16 studies were included in the systematic review, with 10 being determined as having a high risk of bias. Pulpotomy showed an overall mean success rate of 92% after 1 year. The meta‐analysis indicated a significantly higher success rate for pulpotomies utilizing MTA in comparison with calcium hydroxide, while no significant difference was seen between MTA and calcium‐enriched mixture (CEM) or Biodentine. The GRADE assessment revealed an overall low level of evidence for the included studies. Discussion: Most randomized controlled trials exhibited a significant absence of control over confounding factors. Conclusions: This systematic review and meta‐analysis demonstrate that pulpotomy is a highly effective treatment for managing permanent teeth. The results indicate that the success rate of pulpotomy using ProRoot MTA is significantly higher than when using calcium hydroxide. However, the certainty of evidence supporting these findings is low, and there is a need for well‐designed RCTs to assess the long‐term outcomes of pulpotomy using newer bioceramic materials. Registration: This systematic review was registered in the PROSPERO database (registration number CRD42023393970). [ABSTRACT FROM AUTHOR]

Pigs are diphyodonts with heterodont dentition and have been used in studies involving teeth and jawbone regeneration, and dental implants. Patterns of tooth eruption are used to age animals and determine the effects of environmental and genetic influences on occurrence of variations. As with other species, variations exist in the tooth eruption pattern in pigs. The aim of this study was to determine the permanent teeth eruption patterns of Nigerian local pigs. Twenty-six healthy pigs were observed throughout the study period. Pigs were firmly held in dorsal or lateral recumbency and their mouths gently held open to visually examine all quadrants of the dental arches (right and left maxillary, right and left mandibular). Observations were recorded from 16 weeks of age, until the last permanent tooth erupted. Results obtained from the study showed that males had lower mean values for eruption time (54%) of examined teeth in comparison to females. The mean values of eruption time for the maxillary third incisor, the mandibular and maxillary canines, and the mandibular fourth premolar teeth were statistically significant in the males (P =.0017, P =.0088, P =.0002 and P =.0244, respectively). Sixty-nine percent of the adult pigs did not have eruption of the mandibular first premolar, while polydontia was observed in the maxillary and mandibular incisors. These results show that intra-breed and inter-breed variations exist in the dental eruption pattern in pigs. The data obtained from this study can be used for comparative dental studies and can aid further research on the developmental anatomy of Nigerian local pigs. [ABSTRACT FROM AUTHOR]

Traumatic Dental Injuries (TDI) have emerged as a very significant public health and social problem, especially among children and adolescents. The aim of this study was to investigate the prevalence and associated risk factors of traumatic dental injuries to permanent anterior teeth in school going children of Kolkata aged 7-14 years. A cross-sectional study was conducted among 3762 school going children attending various private and public schools of Kolkata aged 7–14 years. A multistage random clustering sampling technique was adopted to select the children.Type of trauma using Ellis and Davey classification of fractures along with Andresen's Epidemiological Classification of Traumatic Injuries to Anterior Teeth, including WHO codes, was used. All values were considered statistically significant at P < 0.05. Prevalence of TDI to anterior teeth was found to be 9.89%. The mean age of children who presented with TDI was 11.06 ± 1.99.years. The most common place of occurrence of TDI was home. Falls were the most common causes of trauma. Children belonging to higher socioeconomic status were observed to have an increased prevalence of TDIs.The highest potential risk factor for the occurrence of trauma was a past history of trauma. Present study found a prevalence of 9.89%, and a very low percentage of children had received treatment. [ABSTRACT FROM AUTHOR]

Pulpotomy has been used in primary teeth and immature permanent teeth. However, with the advent of new bioactive material, the procedure is shifting towards permanent teeth with mature apices of roots. The objective of this systematic review was to evaluate the success of pulpotomy on mature permanent teeth with acute irreversible pulpitis and to compare it with root canal treatment or between the effectiveness of the bioactive material used. The following databases were searched: PubMed, Cochrane Library: Cochrane Central Register of Controlled Trials, Embase, ClinicalTrials.gov, International Clinical Trials Registry Platform. After using the keywords predefined, the electronic search yielded a total of 86 articles. After undergoing a thorough screening and eligibility process, only four articles were finally selected. Unexpectedly, pulpotomy demonstrated a better tendency for success in such cases over the years. This shows that pulpotomy is not inferior to root canal treatment for permanent treatment of irreversible pulpitis. In addition, the results obtained showed that pulpotomy is rapid, biologically reliable and more cost‐effective in all situations compared to root canal therapy. Complete pulpotomy appears to have a high success rate as a permanent treatment of irreversible pulpitis and could be considered as an alternative to root canal therapy. Pulpotomy is not inferior to root canal treatment for a permanent treatment of irreversible pulpitis. In addition, the results obtained have shown that complete pulpotomy is faster and more profitable in all situations compared to root canal treatment. Furthermore, with the advent of new so‐called bioactive materials, the use of this therapeutic is increasingly considered. This is why a review based on studies of reliable articles is above all necessary to be able to generalise the indication of this therapy. [ABSTRACT FROM AUTHOR]

Abstract Objectives The objective of this review is to assess the available literature systematically related to the effect of silver diamine fluoride (SDF) for the management of occlusal and root carious lesions in permanent teeth regardless of age. Materials and Methods This systematic review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Review and Meta‐Analyses statement. A literature search was performed using PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, DOAJ, and Open Gray with no language restrictions up to December 2022. Three reviewers critically assessed the studies for eligibility. Any disputes between the reviewers were handled by a fourth independent reviewer. The quality assessment and data extraction of the studies were performed. Results A total of 2176 studies were screened. The titles and abstracts of the studies were then reviewed (n = 346), and 52 studies met the search criteria. Following the full‐text review, 11 studies investigated the effect of SDF against other treatments such as chlorhexidine, sodium fluoride, ammonium bifluoride, tricalcium silicate paste, casein phosphopeptide amorphous calcium phosphate, glass ionomer cement (GIC) combined with fluoride varnish, resin‐modified GIC, and atraumatic restorative treatment were assessed. Conclusions Within the limitations of this review, the use of SDF is promising with high preventative fractions in permanent teeth of children and older populations when compared to other topical applications such as dental varnish containing sodium fluoride.

Background: Pulp stones are calcified masses with unknown etiology in the dental pulp complicating access to the pulp and root canals during root canal therapy. Aim of this study is to determine the prevalence of pulp stones in patients referring to Kerman University School of Dentistry.Methods: This cross-sectional study was undertaken on 4413 teeth in 852 patients and 1052 bitewing and periapical radiographs. The patients were 3–60 years old and had been referred to the Kerman School of Dentistry for various reasons. Data were collected by radiographic evaluations and the use of a checklist and were then analyzed using SPSS version 19 and the chi-square test with the significance level set at 0.05.Results: The prevalence of pulp stones was estimated at 13.4% in the patients, significantly increasing with age (P = 0.001). Most pulp stones were 12.2% in the maxilla and 10.4% in the mandible, indicating a significant difference between the two jaws (P = 0.001). The highest prevalence of pulp stones was related to the permanent first molars. Most pulp stones were significantly higher in female subjects than in males (P = 0.004), with no major difference between the left and right sides (P = 0.07). No significant relationship was found between the prevalence of pulp stones with tooth restoration and dental caries (P = 0.130).Conclusion: The prevalence of pulp stones increased significantly with age. In this study, the youngest participant was a 4-year-old male, and the oldest was a 60-year-old female.

Enamel hypoplasia (EH) is a qualitative defect, and it can have a significant impact on oral health. The aim of this study was to evaluate the prevalence of enamel hypoplasia in urban area in Albania. Methodology: In total, 234 children of both sexes aged 8–12 years old were randomly selected in five schools in Tirana, Albania. They underwent an intra-oral examination. Diagnostic criteria were in accordance with a European meeting on MIH held in Athens, 2003, and the FDI. Medical history was retrieved using questionnaires, and data obtained from clinical examination were recorded. Results: The prevalence of enamel hypoplasia was 12.8%. The most commonly occurring enamel hypoplasia was the mild type (58.62%). The mandibular first molar showed the highest prevalence of enamel hypoplasia (19.5%), and the maxillary canines and premolars were the least affected (2.3%). In this study, medical story did not have a significant effect on enamel hypoplasia. Conclusions: The prevalence of enamel hypoplasia remains high at 12.8%. Interestingly, the features of enamel hypoplasia were consistent across both sexes, with no correlation found between them. The predominant occurrence of mild enamel hypoplasia underscores the importance of implementing oral hygiene strategies in schools to mitigate its progression.

Purpose: To assess the current prevalence of caries, gingival bleeding, calculus, and fluorosis and to determine the risk factors for caries in permanent teeth of 12-year-old students in Guangdong Province, China.Materials and Methods: A cross-sectional survey was carried out among 1920 12-year-old students in Guangdong Province. All participants were required to undergo an oral health examination. Information concerning the subjects' family background, dietary habits, and relevant oral health behaviour were collected in a structured questionnaire. Chi-squared tests, Wilcoxon rank-sum tests, and the logistic regression model were used in the statistical analysis.Results: The prevalence rates of caries in permanent teeth, gingival bleeding, calculus, and fluorosis were 43.07%, 40.57%, 43.75%, and 5.05%, respectively; the average decayed, missing, and filled teeth (DMFT) index was 1.06±1.721. Residence (odds ratios [OR] rural=1.798, 95% CI: 1.485-2.177), sex (OR female=1.352, 95% CI: 1.121-1.631), paternal education level (OR >9 years=0.755, 95% CI: 0.608-0.936), presence of calculus (OR yes=1.279, 95% CI: 1.057-1.548), and frequency of consumption of sugary snacks (OR frequently=1.418, 95% CI: 1.064-1.890) were statistically significantly associated with the risk of permanent teeth caries.Conclusion: Oral health in 12-year-olds in Guangdong Province remains to be improved. Rural residence, female sex, the presence of calculus, and frequent consumption of sugary snacks could increase the risk of caries. The paternal educational level was negatively associated with the risk of caries, whereas we found no association between the maternal educational level and the risk of caries in this population.

Objective: To compare the clinical performance of two glass-ionomer cements in combination with two light-cured coatings in Class II cavities. Method and materials: In total, 43 Equia Fil/Equia Coat and 42 Fuji IX GP Fast/Fuji Coat LC restor-ations were placed, in 34 patients. Only Class II cavities with two- or three-surface restorations were included. The clinical performance was evaluated at baseline, after 1, 2, and 3 years using the FDI criteria. For the statistical analysis, Fisher exact test, Wilcoxon signed-rank test and Mann-Whitney U test were applied. The success and survival of the restorations were cal-culated with the Kaplan-Meier method and a log-rank test was used to detect significant differences between the tested ma-terials. Results: At the 3-year recall, no significant differences could be detected between the two glass-ionomer cements for any of the evaluated criteria (Mann-Whitney U test, P > .05).

The present study aimed to analyze the gender dimorphism in odontometrics of permanent maxillary canines using a three-dimensional digital method and to test the accuracy in gender estimation using discriminant function analysis in a sample of the Saudi population. A total of 120 diagnostic dental casts of patients aged 16–29 years were used in the present study. Plaster models of their maxillary dentition obtained from the archives were scanned and digitally measured using a three-dimensional digital method. The mesiodistal width of the right and left maxillary canines and intercanine distance were measured. Gender dimorphism was established using the Garn method. Data were statistically analyzed using descriptive statistics, the Mann–Whitney U test and discriminant analyses. Males showed larger mean dimensions of canines than females with regard to both mesiodistal width and intercanine distance, and the difference was statistically significant (p < 0.05). The right maxillary canine mesiodistal width showed a higher percentage of gender dimorphism (3.5%). Discriminant function analysis showed that the overall accuracy of gender prediction was 80.5% for the multivariate analysis. The univariate discriminant function equation revealed that intercanine distance was the most accurate predictor of gender (78%), followed by the right canine mesiodistal width (76.3%). The use of three-dimensional technology for odontometrics presents a promising method, and permanent maxillary canine parameters can be used as an acceptable ancillary tool for gender estimation in forensic science.

Objective: The goal of this systematic study was to investigate the effectiveness of selective, stepwise, and non-selective removal techniques for caries removal in permanent teeth with deep carious lesions. The primary focus was the results found comparing techniques for caries removal to check whether there was pulp exposition; the secondary was the materials used for pulp protection and clinical findings reported within the included studies. Methods: The search was performed in two databases (PubMed/MEDLINE and Web Of Science). The studies included in this systematic review were selected based on eligibility criteria. The inclusion criteria were: (1) randomized controlled trials (RCTs), (2) that compared the total removal of carious tissue with selective removal in permanent teeth with deep carious lesions, (3) with a follow-up period of at least 6 months, and (4) publications in English. Regarding the exclusion criteria, the following were not considered: (1) articles published in other languages, (2) articles that did not compare the different types of total/selective decay removal, and (3) articles published before January 2008. The risk of bias and the quality of the included studies were independently assessed by two reviewers using the RoB 2 tool. Results: 5 out of 105 potentially eligible studies were included. Regarding the teeth included in the study, three articles performed management only on permanent molars, while other studies also performed management on incisors/canines/premolars/molars. Management protocols were divided into nonselective caries removal and partial caries removal (selective/stepwise). The theory of non-selective caries removal was considered an excessive, unnecessarily invasive option and a form of outdated management, and selective removal was preferred. Conclusion: The selective removal technique presented a higher success rate and fewer incidences of pulpal exposure than total removal, after up to 18 months of follow up. Moreover, only one session seemed to be a better management choice compared to two sessions because the cavity re-opening procedure is more prone to pulp exposure and highly depends on patient commitment. Otherwise, at 5 years of follow up, there was no difference between selective removal and total removal in management longevity. In addition, there were also no differences between the success of the materials used for definitive restorations in teeth subjected to any of the techniques evaluated. [ABSTRACT FROM AUTHOR]

The issue of improving dental care protocols for children with multiple (decompensated) and complicated caries of permanent teeth, their full rehabilitation is particularly relevant, especially in periods of social cataclysms (the COVID-19 pandemic, martial law, etc.). The purpose of this study was an assessment of the dental caries experience, analysis of modern approaches to diagnosis, treatment, prevention and rehabilitation of complicated caries of permanent teeth among children in Kyiv. The material of the study was data from medical histories of 236 children aged 7-18 years. During the analysis of the obtained data, the dental caries experience, % of cases of toothache complaints and part of the need for replacement or correction of restorations after the treatment of complicated caries were calculated. The prevalence of caries of permanent teeth among 7-18-year-old children (n=236) in the period 2020-2023 was 42-95%, the dental caries experience – 1.73-6.4, the frequency of diagnosis of complicated caries – 4.8-37,1%, the prevalence of toothache – 31%, the part of the need for replacement of restorations after treatment of complicated caries – 62%. The obtained indicators confirm the absence of a downward trend compared to similar data for more than 15 years of observation. Diagnosis, treatment and full rehabilitation of complicated caries of permanent teeth in children is complex, multi-stage and requires the practical experience and patience of a dentist and the usage of the most modern materials and technologies. To date, there are no clear scientifically based protocols for the restoration of permanent teeth, in particular with incomplete root formation, after endodontic treatment. The usage of modern technologies of orthopedic dentistry and materials science (3D scanner, 3D printer, T-scan, polymers) will allow to significantly improve the quality of comprehensive treatment and rehabilitation of children with complications of caries of permanent teeth.

Purpose: Using a systematic review to answer the following question: What are the treatment patterns for mild and severe molar hypomineralization in permanent teeth? Methods: Electronic searches were conducted to identify randomized clinical trials (RCT) that related treatment to molar hypomineralization- (MH) affected permanent molars in children from five to 16 years old. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool, were performed for all included studies. Studies were selected according to PICOS criteria. RCTs relating mild and severe MH to treatments on permanent molars were included. Studies analyzing clinical techniques, whether single or any association of techniques for restorative and desensitizing treatments, were included. Studies involving another disease or comparing different types of enamel defects related to trauma and hereditary were excluded. The certainty of the evidence was evaluated using the GRADE approach. Results: The electronic search was performed on MEDLINE via PubMed, Embase, Cochrane Library, and Grey literature up to May 9, 2022. Of the 5,201 studies initially identified, 88 were fully assessed and 14 RCTs were included. A total of 2,399 interventions were analyzed in 576 patients. Certainty of evidence was found to be of low quality for the outcomes remineralization, structural integrity maintenance, and decay prevention, and very low quality for hypersensitivity decrease and retention. Conclusions: Mild molar hypomineralization needs remineralization, desensitization, sealants, and close follow-up. Severe MH requires restoration both to treat hypersensitivity and reconstruct the affected teeth. Yellow-brown defects have a poor prognosis. [ABSTRACT FROM AUTHOR]

Aims and Objectives: The aim of this in vitro study was to evaluate the remineralization effect of calcium glycerophosphate (CaGP) in fluoride mouth rinse on permanent enamel eroded by a soft drink. Materials and Methods: Forty sound permanent premolars were embedded in self-curing acrylic resin and immersed in Coca-Cola to create erosive lesions. The teeth were divided into four groups (n = 10): Group I artificial saliva; Group II sodium fluoride; Group III sodium fluoride + sodium monofluorophosphate; and Group IV sodium monofluorophosphate + CaGP. The specimens in the assigned groups underwent pH cycling for ten days. The baseline, after erosion, and after remineralization surface microhardness (SMH) values were determined. The data were analyzed by one-way analysis of variance (ANOVA). The mean SMH value between groups and one-way repeated measures ANOVA for the mean SMH value within each group and Bonferroni's for multiple comparisons at a 95% confidence level were determined. The average SMH was used and calculated as the percentage recovery of SMH. Results: After being eroded by the cola soft drink, the mean SMH values in all groups were significantly decreased. After remineralization, Group I had the lowest %SMHR. The %SMHR of Groups II, III, and IV were significantly higher than Group I (P < 0.001). However, there were no significant differences among Groups II, III, and IV (P > 0.05). Conclusions: Fluoride mouth rinse with and without CaGP showed similar efficacies in remineralizing eroded permanent enamel. [ABSTRACT FROM AUTHOR]

This research aims to evaluate whether the socio-environmental changes observed in the Central Pampas Dunefields (Argentina) throughout the Holocene (ca. 11,000–350 cal year BP) caused episodes of systemic stress in hunter-gatherer populations. Linear enamel hypoplasia was analyzed macroscopically with a 40 × magnifying glass and oblique light in 337 teeth from 26 adult individuals recovered from 11 archaeological sites. Data were analyzed following three levels of observation: individual, tooth, and number of dental enamel lines. 42.3% of the individuals presented linear enamel hypoplasia. The lines affected males and females similarly. No statistically significant differences were observed between the three Holocene periods. The age of growth-disruption events occurred between 2 and 6.05 years, and stress episodes are registered at earlier ages in the Late Holocene than in the other periods. The causes could be related to metabolic stress associated with weaning, post-weaning, variations in the availability of natural resources over time, development of infectious, and parasitic diseases during changes in social organization strategies and gastrointestinal diseases caused by non-potable water intake. At the regional level, Pampas shows moderate to high values of linear enamel hypoplasia, suggesting the exposure of hunter-gatherer groups to recurrent episodes of stress during the early stages of postnatal life.

The authors studied the treatment effect of full pulpotomy using a calcium silicate–based bioactive ceramic in adult permanent teeth with symptoms indicative of irreversible pulpitis. Eighty-one adult permanent teeth with symptoms indicative of irreversible pulpitis in 78 patients aged 18 through 72 years were evaluated for inclusion in the study. After caries excavation, the pulp was amputated to the level of the canal orifices. After hemostasis was achieved, calcium silicate–based bioactive ceramic was placed as the capping agent. The cavity was sealed temporarily with a glass ionomer cement and then restored with flowable resin and composite resin after 2 weeks if no positive symptoms were reported or detected. Postoperative evaluation was performed by means of clinical and radiographic examination at 2 weeks and 3, 6, and 12 months. Overall success rates of the procedure were 96.3% (78 of 81), 93.8% (76 of 81), 92.6% (75 of 81), and 92.6% (75 of 81) at the 2-week, 3-month, 6-month, and 12-month recall visits, respectively. Six of the 81 teeth failed and required root canal therapy. In these 6 teeth, 3 exhibited severe cold stimuli pain and spontaneous pain at the 2-week follow-up, 2 had no response to electric pulp testing with apical percussion pain and periapical rarefaction at the 3-month follow-up, and 1 tooth exhibited periapical rarefaction and labial mucosal fistula at the 6-month follow-up. Under the conditions of this study, full pulpotomy using a calcium silicate–based bioactive ceramic was a successful option for the treatment of adult permanent teeth with carious originated symptoms indicative of irreversible pulpitis. Vital pulp therapy is no longer impossible for adult permanent teeth with carious originated symptoms indicative of irreversible pulpitis. [ABSTRACT FROM AUTHOR]

Abstract Background In recognition of the risk factors common between oral diseases and various chronic conditions and the intersection between oral health and some sustainable development goals, the current cross-sectional study was designed to quantify the burden of dental caries and identify factors associated with its occurrence in permanent teeth. Methods Using data from Egypt's population-based survey (2013–2014), two individual-level outcomes; past caries experience (DMFT > 0) and presence of untreated carious lesions (DT > 0) were assessed using the WHO basic methods for oral health surveys. Information on potential explanatory variables including sociodemographic characteristics, exposure to fluoridated water, dental attendance, and dental anxiety was gathered using a structured questionnaire. Stratified multistage cluster random sampling was used to recruit survey participants. Multivariable logistic regression was performed to identify significant potential risk factors for caries in the permanent dentition of Egyptians. Findings A total of 9,457 participants were included of which 70.3% had at least one untreated carious lesion. After adjusting for all covariates, analphabetic Egyptians were found to have significantly higher odds of caries experience in permanent dentition DMFT > 0 (OR 1.54, 95% CI [1.20–1.98]), DT > 0 (OR 1.62, 95% CI [1.32–2.00]). Males, however, had significantly lower caries risk DMFT > 0 (OR 0.75, 95% CI [0.67–0.85]), DT > 0 (OR 0.81, 95% CI [0.73–0.89]) when compared to females. Regarding age, mean DMFT scores were significantly lower in age groups (6–15 years) (OR 0.03, 95% CI [0.014; 0.082]), (16– 20 years) (OR 0.09, 95% CI [0.037; 0.23]), and (21–35 years) (OR 0.22, 95% CI [0.09; 0.53]) than among people ≥ 60 years. Conclusion Addressing individual-level caries risk factors should be complemented by addressing upstream factors to reduce burden of untreated dental caries among Egyptians.

This study aimed to evaluate the in vitro performance in detecting caries around composite restorations in permanent posterior teeth and the impact of treatment decisions of two visual criteria: International Dental Federation (FDI) criteria and the Caries Associated with Restorations and Sealants (CARS) system. The correlation among secondary caries and the presence of gap measured with a three-dimensional (3D) intraoral scanner was also aimed. One hundred sixteen teeth were assessed by a trained and calibrated examiner according to the FDI criteria or CARS system. A second examiner measured the gap on the 3D models using specific software. The reference standard was the histological examination performed by a third examiner blind to the other evaluations. Other 30 extracted permanent teeth were used only to assess the reproducibility of the methods. The same random sample was selected for re-examination by all three methods, and there were 7 days between the examinations. Unweighted and weighted kappa tests were conducted to assess intra-examiner reproducibility. Spearman's correlation coefficient (Rho) and 95% confidence intervals (95% CI) were calculated between the histological examination and scores obtained with FDI criteria, CARS system, and treatment decisions. Spearman's correlation between the visual and scanner evaluation with the reference standard was performed. Spearman's rank correlation analyses were conducted independently between the gap evaluated and measured by the visual inspection with the gap assessed using the scanner. The reproducibility of the visual score systems reached high values. Spearman's correlation coefficients (Rho; 95% CI) between the following variables versus histology were the FDI presence of caries (0.65; 0.53–0.74); CARS scores (0.65; 0.52–0.74); FDI treatment decision (0.46; 0.31–0.59); and CARS treatment decision (0.62; 0.49–0.72). Rho (95% CI) between histology and the gap assessment by the visual inspection was 0.59 (0.45–0.70), the gap measurement by the visual inspection was 0.49 (0.33–0.62), and the gap measured by the scanner was 0.37 (0.18–0.53). Both visual criteria present similar performance in detecting caries. The correlation among treatment decisions is moderate for the FDI and CARS criteria, and both are moderately correlated with lesion depth, with a slight CARS superiority. However, visual examination presents better performance than the 3D intraoral scanner on gap size assessment. [ABSTRACT FROM AUTHOR]

Objectives: The objective of this review is to assess the available literature systematically related to the effect of silver diamine fluoride (SDF) for the management of occlusal and root carious lesions in permanent teeth regardless of age. Materials and Methods: This systematic review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Review and Meta‐Analyses statement. A literature search was performed using PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, DOAJ, and Open Gray with no language restrictions up to December 2022. Three reviewers critically assessed the studies for eligibility. Any disputes between the reviewers were handled by a fourth independent reviewer. The quality assessment and data extraction of the studies were performed. Results: A total of 2176 studies were screened. The titles and abstracts of the studies were then reviewed (n = 346), and 52 studies met the search criteria. Following the full‐text review, 11 studies investigated the effect of SDF against other treatments such as chlorhexidine, sodium fluoride, ammonium bifluoride, tricalcium silicate paste, casein phosphopeptide amorphous calcium phosphate, glass ionomer cement (GIC) combined with fluoride varnish, resin‐modified GIC, and atraumatic restorative treatment were assessed. Conclusions: Within the limitations of this review, the use of SDF is promising with high preventative fractions in permanent teeth of children and older populations when compared to other topical applications such as dental varnish containing sodium fluoride.
