This study aimed to investigate the association between serum vitamin D levels and untreated caries and determining factors in children and youth. Methodology: This cross-sectional study used data from the National Health and Nutrition Examination Survey (2013-2014). In total, 3,072 participants with ages ranging from 1 to 19 years were included in our sample. The main dependent variable, untreated caries, was defined as having at least one untreated carious surface in any tooth. Serum concentration of 25-hydroxyvitamin D [25(OH)D] was categorized into four groups: ≥75 nmol/ml, 50-74.9 nmol/ml, 25-49.9 nmol/ml, and

The objective was to investigate the experience of dental caries and associated factors from the children’s and adolescents’ medical records who visited the Children's Dental Clinic of a College of southern Brazil. A cross-sectional study was carried out by analyzing 262 medical records. For data collection, information on demographic data, oral hygiene, food, breastfeeding and oral clinical data were used to investigate. A multivariate analysis was used to estimate the odds ratios (OR) and their 95% confidence intervals, by the exposure variables in a Binary Logistic Regression model (p-value< 0.05). Of the sample, 86.3% had some teeth with experience of dental caries, with only 13.7% free of caries. The average dental caries was 5.3 ± 3.1 in children between 6 and 8 years and 2.0 ± 1.9 between 9 and 12 years. There was a statistically significant association between age and dental caries, with the largest age group being a protective factor for dental caries (OR 0.30; 95%CI 0.17-0.53). Children who were breastfed naturally had a protective factor for caries (OR 0.29; 95%CI 0.10-0.88). The experience of dental caries in children was high, especially in primary teeth, with a higher average of decayed teeth. Breastfeeding and age were a protective factor for dental caries.

Background: This study analyzed the most prevalent diagnoses of oral lesions submitted to biopsy using data from a pathology laboratory and associations between malignant and oral potentially malignant disorders with patient’s demographic variables and the anatomical location. Methods: This is a cross-sectional study. All 1,298 histopathological reports of oral lesions recorded in the database of the Institute of Pathology were reviewed. Demographic variables, anatomical location of the lesion, histopathological diagnosis of the lesions and their biological behavior were analyzed using a logistic regression. Results: Regarding the biological behavior of the identified lesions, benign lesions were predominant (70%), followed by lesions of undetermined behavior (14.3%), malignant lesions (14.2%), absence of histological alteration in the sample (1.2%), and finally, oral potentially malignant disorders (0.5%). The anatomical locations of the most prevalent oral lesions potentially malignant disorders and malignant were in the following structures of the oral cavity: gums, roof of the mouth, floor of the mouth, inner lining of the cheeks (P=49.2%), and tongue (P=48.7%). In the final adjusted model, the probability of malignant and premalignant lesions was higher among males (PR= 4.21; 95% CI 2.08-6.22), the increase in age (PR = 1.06; 95% CI 1, 05-1.08), and in the tongue region (PR = 5.48; 95% CI 1.67; 17.92). Conclusion: This study suggests that the probability of identifying malignant and oral potentially malignant disorders is higher in males whit age advanced and specimens from the tongue.

Candida species are commensal to normal oral microbiota; however, they can cause infections if immune functions are reduced. The aim of this study was to investigate oral colonization, identify species, and test the susceptibility profile to antifungals. A descriptive study included 97 liver transplant patients who attended the transplant center of a referral hospital in southern Brazil. Two oral swab collections were performed, with a 6-month gap between collections. The samples were identified by sequencing the internal transcribed spacer ITS region of the ribosomal DNA. The sensitivity test was performed with fluconazole, amphotericin B, and micafungin using a broth microdilution method recommended by Clinical and Laboratory Standards Institute document M27-A4. Eighty-two patients were investigated and 15 were excluded for presenting clinical infection. The identification of yeasts showed colonization in 66% and 61.9% in collections A and B, respectively. Candida albicans was the most prevalent species in both collections (n = 29/50 and n = 27/49, respectively). In 31 (62%) patients, the yeast species remained the same for 6 months, and in 19 (38%) the colonizing species was substituted. Thirty-two isolates from collection A were sensitive (S) to Fluconazole, 13 sensitive dose-dependent (SDD), and five resistant (R). In collection B, 32 were S, 12 SDD, and 5 R. For amphotericin B and micafungin, all isolates were sensitive. With knowledge of the species and identification of strains resistant to fluconazole, useful information can be alerts about the emergence of antifungal resistance strains. Lay summary Study of great importance because it is the first investigation that identifies Candida in the oral cavity of liver transplant patients, allowing an understanding of epidemiology and contributing to the knowledge about strains resistant to fluconazole.

AIM: This study aimed to analyze the association between emotional distress and glycated hemoglobin (HbA1c) values in adolescents and young adults with type 1 diabetes mellitus (T1DM), with respect to dental anxiety, microvascular diabetes chronic complications, demographic conditions. METHOD: The cross-sectional study design included 100 adolescents and young adults with T1DM, from regional diabetes reference center. The clinical and laboratory data were obtained from medical records. Distress and dental anxiety scales were produced from questionnaires that were validated for emotional distress (DDS) and dental anxiety (Corah Scale). Multiple analyses estimated odds ratios and their respective 95% confidence intervals using a binary logistic regression model (P

This study evaluated the prevalence of dental implant positioning errors and the most frequently affected oral regions.A sample was obtained of CBCT images of 590 dental implants from 230 individuals who underwent diagnosis at a radiology center using cone-beam computed tomography from 2017 to 2020. The following variables were considered: thread exposure, violation of the minimum distance between 2 adjacent implants and between the implant and tooth, and implant contact with anatomical structures. Descriptive data analysis and the Pearson chi-square test (Most (74.4%) of the 590 implants were poorly positioned, with the posterior region of the maxilla being the region most frequently affected by errors. Among the variables analyzed, the most prevalent was thread exposure (54.7%), followed by implant contact with anatomical structures, violation of the recommended distance between 2 implants and violation of the recommended distance between the implant and teeth. Thread exposure was significantly associated with the anterior region of the mandible (Many implants were poorly positioned in the posterior region of the maxilla. Thread exposure was particularly frequent and was significantly associated with the anterior region of the mandible.

Aim: To evaluate the impact of xerostomia, edentulism, use of dental prosthesis, and presence of chronic diseases on quality of life in relation to oral health in institutionalized elderly individuals. Methods: This is a cross-sectional study. A questionnaire was administered containing the following instruments: Oral Health Impact Profile (OHIP-14), which measures the quality of life related to oral health; the Summated Xerostomia Inventory questionnaire (SXI-PL) for evaluation of xerostomia, sociodemographic data, clinical description, and patient-reported factors was assessed (edentulism, use of dental prostheses, and chronic diseases). Results: Most elderly individuals did not have any teeth in their mouths and used dental prosthesis. The impact on quality of life, considering the mean of the OHIP-14 scores, was positive in 58.3% of the elderly. Those who used a dental prosthesis were three times more likely to have their oral health negatively impacted (OR=3.09; 95%CI =1.17 8.11), compared to those who did not use, and individuals with xerostomia were more likely to have their oral health negatively impacted (OR=1.57; 95%CI=1.25-1.98) compared to those without xerostomia. There was no difference in the quality of life of individuals with and without chronic diseases. Conclusions: The feeling of dry mouth and use of dental prostheses negatively impacted the quality of life in relation to oral health of the elderly.

Aim The objective of this study was to assess apical extrusion after filling material removal using two systems, one rotary and one reciprocating. Materials and methods A total of 34 extracted mandibular premolars with single roots were selected and, posteriorly, prepared and filled. Following material aging for 60 days, teeth were divided into two groups, according to the method used to remove root filling material: group I, ProTaper® Universal Retreatment instruments plus refining with the Hero 642® sequence and group II, WaveOne® instruments. The teeth were fixed in an apparatus designed to collect the extruded material during removal procedure. Data on the amount of debris extruded (mg/weight) were analyzed using the Student's t test with a significance level of 5%. Results No significant differences were found between the groups with regard to the amount of material extruded during root canal retreatment. Conclusion The present findings suggest that the extrusion of debris during apical root canal retreatment does not depend on the instrument design or the protocol employed. Clinical significance Regardless of root canal clearance techniques, debris extrusion eventually occurs during endodontic retreatment and may be related to postoperative pain.

Childhood is a period of life when the human being is constantly going through progressive steps of psychosocial, physical, and mental development. The quality of hygiene habits of family members will be reflected on the characteristics and attitudes of children, which significantly increases the responsibility of the family in oral hygiene education. The present study aimed to observe the influence of maternal satisfaction with the dentist in children's oral care. This is a cross-sectional design, which sample included 100 mothers from a city in Southern Brazil. From a questionnaire prepared for this purpose and adapted from previous research, the mothers were interviewed from January to July 2015. The results presented showed that most mothers work outside the home (46.4 %) but monitor their children during toothbrushing (50.7 %). For most mothers, the dentist represents satisfaction (37.1 %) and the main reason for seeking the dentist is oral health (44.3 %). It was found that mothers who encourage their children to use dental floss and monitor them during toothbrushing are the mothers who feel satisfied with the dentist (P < 0.05). In addition, mothers know that caries is a disease and its occurrence is related to diet habits, however, they add chocolate milk and sugar to their children’s bottle. Thus, it was concluded that satisfaction with the dentist influences mothers on oral hygiene habits adopted by their children regarding the use of dental floss and toothbrushing monitoring.

Introdução: Durante o tratamento antineoplásico, células normais também são afetadas, incluindo assim, as células da mucosa oral, o que potencialmente causa complicações orais. Objetivo: O presente trabalho teve por objetivo avaliar a prevalência das principais complicações bucais e índice de higiene oral em crianças e adolescentes submetidas à quimioterapia e/ou radioterapia. Método: O delineamento é do tipo observacional de prevalência realizado em um Hospital do Sul do Brasil. Foram coletados dados de 21 pacientes de 5 a 12 anos de idade em tratamento, a partir de um questionário auto aplicativo para os responsáveis pelos pacientes e um exame clínico intraoral. Os indicadores utilizados foram o índice CPOD (dentes cariados, perdidos e obturados) para cárie dentária, o índice IHOS (higiene oral simplificada) para Higiene Oral e a presença de mucosite, xerostomia e candidíase. Resultados: A maior parte da amostra era do sexo masculino (57,1%) média de 8 anos de idade (dp 2,92), diagnosticados com leucemia (47,6%). Todos os participantes receberam quimioterapia como tratamento de escolha e 38,1% receberam radioterapia como parte do tratamento. Os resultados evidenciariam presença de mucosite em 61,9% e xerostomia em 28,6% dos pacientes. Nenhum paciente apresentou candidíase durante o exame clínico. Quanto a cárie dentária, 66,7% tem um CPOD de 4 e 16, considerado alto e 38,1% dos pacientes apresentaram presença de placa bacteriana e cálculo dentário. Conclusão: As principais complicações bucais evidenciadas durante o tratamento antineoplásico foram mucosite e xerostomia. Foi observado também um alto índice de cárie dentária, consequência de uma inadequada higiene oral.

Aim: to evaluate the association of the patients’ perception about dentist’s affect and cognition on trust and, consequently, on intention to return and patient satisfaction with life. Methods: Analytical cross-sectional study conducted in patients’ adults and elderly at of two dentistry clinics in the south of Brazil. Patients had to have a previous relationship with the dentist (at least one previous consult) and 18 years of age or older. The data were collected through self-administrated questionnaire using measures adapted from other research, using structural equation modeling. We test using a chi-square difference test (p-value

AIM This study aimed to assess the occurrence of postoperative pain and associated factors in patients treated endodontically at a Postgraduate Center in Endodontics in Southern Brazil. MATERIALS AND METHODS The evaluation was performed using the medical records of 658 patients. Pulp conditions, postoperative pain, pain intensity, edema, number of sessions (single or multiple), and medication administration in the postoperative period were analyzed. For data analysis, descriptive analyses and univariate and multiple regressions were performed. In the multiple analyses, odds ratios (OR) and their respective 95% confidence intervals were estimated, crude and adjusted for exposure variables in a binary logistic regression model (p-value < 0.05). RESULTS To perform the adjusted logistic regression, all variables associated with p-value

BACKGROUND: Dry mouth syndrome or xerostomia is defined as decreased salivary flow or hypofunction of salivary glands. Its origins are multicausal and might be the result of a change in the salivary glands or a systemic imbalance. OBJECTIVE: To ascertain the prevalence of self-reported xerostomia and to identify associated factors. DESIGN AND SETTING: Cross-sectional study on the entire population of 293 elderly people over 60 years of age living in a Brazilian municipality. METHODS: Data were gathered from a questionnaire that asked about demographic data, chronic diseases and use of continuous medications, and which used the Xerostomia Inventory (XI) to evaluate dry mouth sensation. Our analysis consisted of multivariate regression and estimation of odds ratios (OR) and their respective 95% confidence intervals (CI) in binary logistic regression models. RESULTS: The prevalence of self-reported xerostomia was 19.1%. Elderly people with diabetes had higher odds of having self-reported xerostomia (OR: 3.59; 95% CI: 1.48-8.68; P < 0.001) as did those who had chronic diseases and used continuous medication (OR: 2.3; 95% CI: 1.19-4.67; P = 0.009). Elderly people who used continuous medication for the gastrointestinal tract were more likely to have xerostomia (OR: 2.14; 95% CI: 1.03-1.44; P = 0.030). CONCLUSIONS: Elderly people with diabetes and chronic diseases who were using continuous medication were more likely to have dry mouth. Use of continuous medications for the gastrointestinal tract led to a greater chance of having self-reported xerostomia.

To verify the presence of periodontitis, its severity, and their association with associated factors based on medical records of patients who attended the Dental Clinic of the Faculty of Southern Brazil over 4 years. This is a cross-sectional study, which included 422 medical records of patients aged ≥ 18 years. The clinically analyzed data were: plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). Sociodemographic data, dental hygiene, harmful habits and chronic systemic diseases were described. Statistical analysis of binary logistic regression was used to verify the relationship between the severity of periodontitis and the exposure variables. The older adults [odds ratio (OR) = 2.36; 95% confidence interval (CI): 1.23-4.54 – 41 to 55 years and OR = 3.0; 95% CI: 1.49-6.09 – 56 to 87 years], and men (OR = 1.9; 95% CI: 1.18-3.14) showed higher chances of periodontitis severity. Smokers (OR = 3.54; 95% CI: 2.05-6.12), those with hypertension (OR = 2.11; 95% CI: 1.23-3.63) and with diabetes (OR = 2.10; 95% CI: 1.08-4.12) showed higher chances of developing advanced periodontitis. Advanced or severe periodontitis occurred in one-third of the patients. The findings showed that men, older adults, with systemic arterial hypertension, diabetes mellitus, and smokers are more susceptible to severe periodontitis.

Aim: This study aimed to evaluate the decision-making by patients to replace temporary restorations with permanent restorations after endodontic treatment and to verify the associated factors and evaluate the quality/integrity of the temporary restorative material within one month. Methods: This is a cross-sectional study using non-probabilistic sampling which analyzed patients after one month of endodontic treatment. The self-administered questionnaire contained sociodemographic, treatment decision-making and endodontic treatment questions. The restoration present in the mouth was evaluated in the clinical oral examination. The Poisson Regression test was used to verify the prevalence ratio. Results: The prevalence failure to perform permanent restorations was 61.1% of patients, and 42.7% reported not having adhered. The reasons are lack of time and not knowing the importance of replacing the restoration with a definitive one. The glass ionomer temporary restorative frequency was higher among those who chose not to replace the temporary restoration with a permanent one (PR=5.19; 95%CI 2.10-12.33). In addition, there was an association between the quality of the restorative material and the type of material, and the best clinical quality of the restoration was statistically associated with glass ionomer and composite resin. Conclusions: The findings show the importance of guidance by the dental surgeon in helping patients decide to replace their temporary restoration.

The objectives of this study were to understand patients’ perceptions and respect for the quality of dental services provided and to evaluate their satisfaction with professional dental surgeons, by considering the relationship between the professional and the patient, trust in use, satisfaction with the treatment performed, understanding, and intention to return for future procedures. A literary review, considering publications from 2005 to 2020 in English and Portuguese, was conducted. The following sources of information were used: Medline/PubMed and BVS/Bireme. For the survey, we used the terms ‘patient satisfaction with dentist’ and ‘patient satisfaction with dental treatment’ and the descriptors ‘dentist’, ‘dentistry’, ‘satisfaction’, ‘dissatisfaction’, and ‘healthcare’ in two languages; consulted in the plural and singular and in synonyms; and used the Boolean terms OR to distinguish them and AND to associate them. Fifty-seven articles from publications from different countries were included according to the inclusion criteria. The findings revealed that people with the lowest socioeconomic status were the most dissatisfied with professionals. Satisfaction concerning their needs and the quality of care provided by the dentist was related to good interpersonal interactions. In addition, the physical characteristics of the facilities and cost of treatment could lead to dissatisfaction with dental services. We conclude that aspects of affectivity, such as trust and a good relationship with the professional and their team, increase the degree of satisfaction.

CONTEXT AND OBJECTIVES: Anxiety is usually classified as a disorder of neurotic nature and is often related to contexts of stress, which may include worries, motor tension and autonomic hyperactivity. The aim of this study was to assess the influence of mothers’ anxiety on their children’s anxiety during dental care. DESIGN AND SETTING: Analytical cross-sectional study conducted at in a private dentistry school in the south of Brazil. METHODS: Convenience sampling was used. All mothers of children undergoing treatment were invited to participate in this study. Data to investigate anxiety related to dental treatment among the children were collected through applying the Venham Picture Test (VPT) scale. For the mothers, the Corah scale was applied. A self-administered sociodemographic questionnaire with questions about demographic, behavioral, oral health and dental service variables was also used. RESULTS: 40 mother-child pairs were included in the study. The results showed that 40% of the children were anxious and 60% of the mothers were slightly anxious. Local anesthesia was the procedure that caused most anxiety among the mothers, making them somewhat uncomfortable and anxious (60%). Family income higher than R$ 1,577.00 had an influence on maternal anxiety (75.6%). Maternal anxiety had an influence on child anxiety (81.3%). CONCLUSION: Most of the children showed the presence of anxiety, which ranged from fear of dental care to panic, inferring that maternal anxiety has an influence on children’s anxiety. Dental procedures did not interfere with the mothers’ anxiety, but caused positive feelings, whereas they affected the children more. RESUMO CONTEXTO E OBJETIVO: A ansiedade é geralmente classificada como um transtorno de caráter neurótico, frequentemente relacionado a contextos de estresse variando entre preocupações, tensão motora e hiperatividade autonômica. O objetivo desta pesquisa foi avaliar a influência da ansiedade materna na ansiedade de seu filho durante o atendimento odontológico. TIPO DE ESTUDO E LOCAL: Estudo analítico transversal realizado em uma faculdade particular do sul do Brasil. MÉTODOS: Amostragem por conveniência foi utilizada. Todas as mães das crianças em tratamento foram convidadas a participar da pesquisa. A coleta dos dados para verificar a ansiedade relacionada com o tratamento odontológico nas crianças foi realizada a partir da aplicação da escala “Venham Picture Test” (VPT). Para as mães, foi utilizada a escala de Corah. Também se utilizou um questionário sociodemográfico autoaplicativo sobre variáveis demográficas, comportamentais, de saúde bucal e de serviço odontológico. RESULTADOS: Foram incluídos 40 pares de mães e crianças. Os resultados mostraram que 40% das crianças estavam ansiosas e 60% das mães estavam levemente ansiosas. A anestesia local foi o procedimento que causou mais ansiedade entre as mães, deixando-as um pouco desconfortáveis e ansiosas (60%). Renda familiar maior de R$ 1.577,00 influenciou a ansiedade materna (75.6%). A ansiedade materna influenciou a ansiedade das crianças (81.3%). CONCLUSÃO: A maioria das crianças apresentou ansiedade, o que variou do medo ao pânico ao atendimento odontológico, inferindo que a ansiedade materna tem influência na ansiedade dos seus filhos. Os procedimentos odontológicos não interferem na ansiedade das mães, atingindo mais as crianças, porém provocam sentimentos positivos.

Objective: To verify whether recreational interaction with pediatric patient before dental care influences cortisol levels and anxiety. Material and Methods: Twelve children were selected and divided into two groups: 6 children who had not previously received recreational intervention (Group I) and 6 children who received recreational intervention before dental care (Group II). Saliva was collected with Salivettes™ kits before and soon after dental care for the measurement of cortisol. Wilcoxon test was applied to verify the difference in salivary cortisol levels before and after the dental visit in the whole sample, and the Mann-Whitney U test was used to analyze the difference between groups I and II. A significance level of 0.05 was considered . Results: Among patients from Group I, 3 had their cortisol levels increased after dental care, 2 had their cortisol levels decreased, and the other 1 patient remained constant. All participants from Group II had no significant difference in cortisol levels pre- and post-procedure. Mean salivary cortisol level was higher in Group I, pre- and post-procedure, compared to Group II . Conclusion: Pediatric patients who participated in an interactive activity prior to dental care have a lower level of anxiety according to the salivary cortisol levels obtained, compared to patients who did not participate in recreation. The techniques for the dentist to approach the child control the anxiety of the patient and make the procedure calmer and less stressful for both of them.

BACKGROUND: People have been using psychoactive substances for a long time. Over the last few years, this practice has spread among university students, who use these substances to improve their academic performance, relieve stress and increase concentration and memory. OBJECTIVES: To estimate the use of psychoactive drugs among healthcare students at a higher education institution in the city of Passo Fundo (RS), Brazil, and to ascertain the associated demographic and lifestyle factors. DESIGN AND SETTING: Cross-sectional study in a higher education institution. METHODS: We included 287 undergraduate medicine and dentistry students in this study. They answered a self-administered questionnaire regarding sociodemographic, lifestyle and health variables. The statistical analysis used univariate and bivariate analyses with Pearson’s chi-square test (P-value < 0.05). ­Multivariate analyses were used to estimate odds ratios (OR) and their respective 95% confidence intervals. The SPSS software, version 20.0, was used. RESULTS: The prevalence of use of psychoactive substances among the students was 24.7%. Among these students, high frequencies of psychoactive drugs had been prescribed by physicians (95.8%) and for the purpose of relaxation or stress relief (73.2%). Women, medical students (compared with dental students) and participants with lower academic performance were more likely to use psychoactive drugs. After the multivariate adjustment, the “course” and “academic performance” remained associated with use of psychoactive drugs. CONCLUSION: There was high prevalence of psychoactive drug use among the students at the higher education institution investigated. Some variables (female sex, medical students and low academic performance) were associated with the outcome.

Context: Anxiety is defined as an emotion produced by a set of feelings and physical changes. Many patients are afraid of some procedures involved in dental therapy. Aim: The objective of this study was to verify the anxiety of patients regarding the visits to dental clinics of a higher education institution, as well as to observe the moment of greatest anxiety. Settings and Design: It is a cross-sectional observational study including 94 patients from the dental clinics of an educational institution in a city of southern Brazil. Materials and Methods: The Corah Dental Anxiety Scale, composed of four questions, was used to evaluate the dental anxiety levels of all patients. The sample universe included registered patients under treatment in the clinics of the studied institution, from August to November of 2016. We included only healthy patients over 18-year old who were subjected to surgical and nonsurgical procedures. Statistical Analysis: The data were analyzed through descriptive statistic to verify the frequency distribution of all variables. Pearson's Chi-square test, at 5% significance level and 95% confidence interval, was used to evaluate the association between the dependent variable (dental treatment anxiety) and the independent variables (demographics), aided by the SPSS software 20.0. Results: It was found that most of the participants were not anxious (69.1%) and the moment of greatest anxiety reported was before local anesthesia. In addition, statistics showed no correlation among gender, age group, and type of procedure performed. It was possible to conclude that the level of anxiety of the patients regarding the dental care performed in the clinics of the studied institution was low for both surgical and nonsurgical procedures. Conclusion: This survey revealed that the moment of greatest anxiety for the patients was before the anesthetic procedure, and gender, age, and type of procedure did not influence the level of anxiety felt by the patient.

Violence against women is a hot topic in the spotlight of contemporary science. In the academy, most of the courses are structured in a hierarchical system, in which students-especially female-become potentially vulnerable to emotional, physical and even sexual harm. This study aimed to describe the prevalence and the study-associated factors of emotional, physical and sexual violence against female students in medical, dental and psychological courses in South Brazil. A questionnaire-based survey was performed combining two previously validated tools for the investigation of workplace violence. The questionnaires were digitally provided to women undergoing medicine, dentistry and psychology courses in South Brazil. The study was conducted between April and July, 2018. The final sample consisted of 241 students (57 medical students; 91 dental students and 93 psychology students). Reports of general violence reached a prevalence rate of 45.2%. In particular, emotional violence reached 78.9% of the cases, whilst physical and sexual violence reached 4.6% and 8.3%, respectively. Amongst the identified offenders, professors figured as the most prevalent (18.4%). Alarming rates of violence against women were detected in this study. Institutional preventive strategies must be designed to protect female students in their study/workplace and enable a safe routine of academic activities.

Objective To perform a systematic search in the literature in order to verify whether the dentists are able to identify and manage cases elder physical abuse. Background Dentists may play an important legal role contributing to the management of abused patients through the identification of injuries in their face, head and neck. Materials and methods The present systematic review was performed following the PRISMA Statement and was registered in the PROSPERO database. A search was conducted in the following electronic databases: PubMed, LILACS, SciELO, Embase, Web of Science, OpenGrey, Google Scholar. Specifically, the last two databases were used to search the ‘grey literature’. The research question was based on the PVO strategy for systematic exploratory review. Two examiners determined the eligibility criteria for selecting the studies and performed all the research steps. Results The initial search resulted in 842 studies, from which eight were considered eligible. Six studies used questionnaires to assess the perception, knowledge and attitudes of dentists towards the identification and management of cases of elder abuse, while two studies assessed this information through personal interviews. Two studies were rated as high quality, while six studies reached moderate quality. Male and female dentists were assessed separately in six studies. Only three studies specified the aggressor. Conclusion The dentists revealed insufficient knowledge on elder abuse. Most of the dentists are not able to identify and manage these cases in the clinical routine.

The domestic violence against children (DVAC) interferes in the psychological development leading to sequels that manifest and persist up to the adulthood. The physical evidences of domestic violence are more easily observed in the orofacial complex, becoming eventually detected by dentists. The present systematic literature review aimed to investigate the perception, knowledge and attitude of dentists towards the detection and management of DVAC cases. A systematic search was performed in 6 databases: PubMed, ScienceDirect, LILACS, SciELO, GoogleScholar, and OpenGrey. Cross-sectional articles assessing the perception, knowledge, and attitude of dentists facing potential cases of DVAC were selected. No restriction of language, time, and publication status was considered. The search resulted in 1.024 articles, of which 18 fit the eligibility criteria. The knowledge for detecting cases of DVAC obtained during the undergraduation course was classified by the dentists (in 39% of the articles) as "insufficient". When suspecting of cases involving domestic violence, most of the dentists (in 77.75% of the articles) considered reporting to the competent authorities. However, the dentists are not sure about who these authorities are (in 31.25% of the articles). More attention must be given to the Forensic education in Dentistry. Specifically, proper training is necessary to support the dentists on the detection and management of pediatric patients under domestic violence. Systematic Review Registration Number: PROSPERO CRD42015026747 (http://www.crd.york.ac.uk/PROSPERO).

This study aims to assess the awareness and attitude of students and professors regarding child physical abuse (CPA) in the routine dental practice. A cross-sectional study has been designed with 117 dentistry students and 29 dentistry professors. A questionnaire was administered to assess their knowledge regarding CPA and their attitude toward the same. It was determined that less than 40.0% of the participants received formal education about CPA during the undergraduate course in dentistry. Most of the students (94.0%) and professors (75.9%) reported that they could identify clinical signs of CPA, including those listed as minor and common injuries among children (i.e., bruising, abrasions, and lacerations). Almost half of the students (47.0%) reported that in cases of CPA, the head and neck were the most affected body parts, while 44.8% of the professors indicated that the arms also could indicate signs of CPA. In the case of suspected CPA, 76.9% of the students, and 79.3% of the professors stated that they would report it to official child protective services. In general, it can be stated that dentistry students and professors are aware of the basic aspects of CPA, especially when it comes to identifying and reporting cases. However, there is still a gap in terms of formal education and training at the undergraduate level regarding the adequate attitude to deal with CPA.

Objective To check knowledge of undergraduate dental students to make diagnosis of dental fluorosis with varying degrees of severity and choose its appropriate treatment. Methods Data were collected using a semi-structured questionnaire addressing knowledge of undergraduates based on ten images of mouths presenting enamel changes. Results Only three images were correctly diagnosed by most undergraduates; the major difficulty was in establishing dental fluorosis severity degree. Conclusion Despite much information about fluorosis conveyed during the Dentistry training, as defined in the course syllabus, a significant part of the students was not able to differentiate it from other lesions; they did not demonstrate expertise as to defining severity of fluorosis and indications for treatment, and could not make the correct diagnosis of enamel surface changes. RESUMO Objetivo Verificar o conhecimento de discentes de um curso de graduação em Odontologia ao diagnosticar casos de fluorose dentária nos diversos graus de severidade, bem como escolher seu tratamento adequado. Métodos O levantamento dos dados foi realizado por meio um questionário semiestruturado, que abordou o conhecimento dos acadêmicos sobre as imagens de bocas contendo alterações do esmalte dentário. Resultados Apenas três imagens foram diagnosticadas corretamente pela maioria dos acadêmicos; a maior dificuldade foi o diagnóstico da severidade da fluorose dentária. Conclusão Apesar das informações sobre fluorose repassadas no decorrer do curso de Odontologia, definidas pelos conteúdos abordados na matriz curricular, expressiva parte dos alunos ainda não soube diferenciá-la de outras lesões, não demonstrando domínio sobre a severidade e as indicações de tratamento, o que indicou desconhecimento no diagnóstico correto das alterações de superfície de esmalte.

Objetivo: O aparelho fotopolimerizador e um instrumento que emite luz capaz de ativar componentes da resina composta e demais produtos odontologicos, polimerizando-os, garantindo a qualidade da restauracao e sua longevidade. Para a efetivacao da fotopolimerizacao as principais fontes emitentes de luz sao as fontes de luz halogenas e os diodos emitentes de luz (LEDs). Todos os aparelhos fotopo­limerizadores sao unidades capazes de perda de rentabilidade de acordo com o tempo de uso. Para que o aparelho fotopolimerizador permaneca com sua intensidade de luz ideal, e importante realizar a manutencao periodica dos aparelhos para garantir a adequada polimerizacao das resinas compostas. O presente estudo teve por objetivo avaliar a potencia dos fotopolimerizadores presentes nas Clinicas Odontologicas do curso de Odontologia da Faculdade Meridional de Passo Fundo – RS, comparando a intensidade de luz de aparelhos novos e usados e verificando a media da potencia de tres afericoes em tempos diferentes. Metodologia: a potencia foi aferida atraves do uso de um radiometro. Foram avaliados 26 aparelhos fotopolimerizadores caracterizados em novos e usados. Resultados: conforme os resultados obtidos houve diferenca estatisticamente significativa, sendo que os aparelhos fotopo­limerizadores usados sao mais potentes que os aparelhos novos. Entre as tres afericoes distintas, a terceira afericao foi a que apresentou a maior media de potencia tanto para os aparelhos novos, como para os usados. Conclusao: desse modo, pode-se concluir que os aparelhos usados sao mais potentes que os novos e dentre as tres afericoes, a que obteve maior media de potencia foi a terceira, tanto para novos como para os usados.

This study aimed to identify the quality-of-life scores of schoolchildren in a city in southern Brazil and to verify the associated factors. This cross-sectional study included the population of all 207 students enrolled, aged between 9 and 15 years. Clinical examinations were performed using the DMFT index for dental caries. Information was also collected from a self-applied questionnaire composed of questions on the quality of life (QOL) and the perception and satisfaction with oral health. The assessment was performed with the short form of the Child Perceptions Questionnaire (CPQ11–14) distributed in domains: oral symptoms, functional limitations, emotional well-being, and social well-being. Descriptive analyses and univariate and multivariate regressions were performed for data analysis, estimating odds ratios and their respective 95% confidence intervals in a logistic regression model. Toothache influenced the lowest QOL scores (63.5%). It was observed that the schoolchildren with toothache over the last six months had 2.9 (95% CI 1.61–4.62) times more likely to present low QOL scores. The findings of the present study showed that toothache affected QOL negatively.

This study aimed to assess the adequacy of prenatal care in Brazil associated with sociodemographic determinants. The study included a data analysis from the National Health Research performed in Brazil in 2013. Two outcomes on the adequacy of prenatal care were assessed: the Kessner index modified by Takeda index that, in addition to the former, assessed whether blood pressure and weight were measured in all appointments, as well as the performance of blood and urine tests and ultrasound. Both quality indicators were assessed for Brazil and for its macro-regions. According to Outcome 1, 80.6% of women received adequate prenatal care. When adding the performance of tests (Outcome 2), the rate dropped to 71.4%. Adequate prenatal care was more frequent among white women who performed prenatal care in the private health sector. The northern region had the lowest rate of adequate prenatal care, while the southeast region showed the highest rates. Despite the extensive coverage, prenatal care in Brazil still presents inequities and low service quality, especially for women from the poorest regions of the country.O objetivo deste estudo foi avaliar a adequação do cuidado pré-natal no Brasil associado a determinantes sociodemográficos. A pesquisa consistiu em uma análise dos dados da Pesquisa Nacional de Saúde realizada no Brasil em 2013. Foram avaliados dois desfechos sobre a adequação do pré-natal, o índice de Kessner modificado por Takeda que, além de levar em consideração esse índice, avaliou se houve aferição da pressão arterial e do peso em todas as consultas, realização de algum exame de sangue e urina e ultrassom. Ambos indicadores de qualidade foram avaliados para o Brasil e também pelas macrorregiões do país. De acordo com o desfecho 1, 80,6% das mulheres realizaram o pré-natal adequado. Ao adicionarmos a realização de exames (Desfecho 2) o percentual foi 71,4%. O pré-natal adequado foi mais frequente entre as mulheres de cor branca e que realizaram o pré-natal na rede privada. A região norte apresentou as menores frequências de pré-natal adequado, enquanto a região sudeste as maiores. Apesar da ampla cobertura, o pré-natal no Brasil ainda apresenta iniquidades e baixa qualidade no atendimento, especialmente entre mulheres das regiões mais pobre do país.

OBJECTIVE: The objective of this study was to verify from a school-based epidemiological survey, the prevalence of anterior open bite, analyzing the influence of pacifier habit in the school. METHODS: The first step was a questionnaire for the parents, and later clinical examinations in 237 school children, 3-14 years old, in the city of Santo Expedito do Sul/RS, Brazil. RESULTS: The population gender distribution was 50.3% boys and 49.4% girls with a mean age of 8.63 years, and 16% had primary dentition, 50.2% mixed dentition and 33.8 % permanent dentition. There was a 22.8% prevalence of anterior open bite, obtaining a significant association between anterior open bite and the pacifier sucking habit on the three dentitions. CONCLUSION: The duration and frequency of the habit were strongly associated with anterior open bite malocclusion in the deciduous and mixed dentitions.

Introdução e objetivo: O objetivo deste trabalho foi verificar a influência de diferentes materiais usados na confecção de infraestruturas no resultado estético de restaurações com recobrimento cerâmico. Material e métodos: Foi selecionado um paciente que necessitava de coroa protética unitária nos incisivos centrais superiores, sendo uma convencional (elemento 11) e outra sobre implante (elemento 21). Para cada elemento dentário, uma coroa livre de metal (sistema Cubo) e uma metalocerâmica (MC) foram confeccionadas e submetidas a avaliação cega por 11 cirurgiões-dentistas. Para isso, os profissionais responderam a um questionário sobre proporções de opacidade e translucidez das coroas na cavidade bucal do paciente, e cada resposta correspondia a uma pontuação. Os dados obtidos foram submetidos ao teste de Wilcoxon (α = 0,05). Resultados: Não houve diferença estatisticamente significante entre as coroas metalocerâmicas e as do sistema Cubo (elemento 11: p = 0,107; elemento 21: p = 0,739). A análise dos escores ainda evidenciou que para um mesmo tipo de infraestrutura não se observou diferença estatisticamente significante entre os elementos 11 e 21 (Cubo: p = 0,206; MC: p = 0,102). Conclusão: Dentro das limitações do presente estudo, foi possível concluir que, de acordo com a percepção visual dos avaliadores, as coroas protéticas confeccionadas com infraestrutura metálica e com infraestrutura cerâmica se apresentaram esteticamente semelhantes e satisfatórias.

Introdução e objetivo: O objetivo deste trabalho foi estudar a prevalência e a severidade da cárie dentária, analisando a influência de alguns fatores socioeconômicos e a fluoretação das águas de abastecimento público. Material e métodos: O delineamento da pesquisa foi transversal de base escolar realizado mediante informações do Levantamento Epidemiológico do Rio Grande do Sul e abrangeu 571 escolares de 12 anos da região norte do Rio Grande do Sul, Brasil. Os resultados foram analisados por intermédio do teste de regressão logística binária. Resultados: Após o ajuste dos dados, os escolares residentes em municípios de pequeno porte tiveram três vezes mais chances de apresentar cárie do que os moradores de cidades de médio e grande porte (RC = 2,94; IC95% = 1,86-4,64). Conclusão:O porte demográfico do município foi o principal fator associado à experiência de cárie dentária nos escolares da região norte do Rio Grande do Sul.

Introdução: O tecido que recobre a coroa dos dentes é o esmalte dentário, que promove proteção e revestimento. Trata-se de tecido mineralizado e sensível às variações do ambiente em sua formação, sendo que não sofre remodelação ao longo de seu ciclo de vida. Objetivo: Avaliar a escolha mais adequada do diagnóstico e opções de tratamento de lesões de esmalte dentário pelos docentes e discentes do curso de Odontologia. Método: Estudo quantitativo descritivo, cuja amostra foi composta por 98 discentes matriculados nas disciplinas de Clínicas Odontológicas do IV ao VIII nível e por 23 docentes. O instrumento de coleta dos dados foi um questionário composto por fotografias de quatro casos clínicos, cujos dentes apresentavam diferentes lesões em esmalte dentário: hipoplasia do esmalte dentário, fluorose dentária, amelogênese imperfeita e cárie dentária. Resultados: Dos 98 discentes, o acerto predominante foi o da fluorose dentária, onde 93,9% acertaram o diagnóstico. Enquanto o acerto predominante em relação ao tratamento foi o das lesões de cárie, onde 86,7% optaram por restauração direta. Dos 23 docentes, o acerto predominante frente ao diagnóstico foi de lesão de cárie, 100% acertaram o diagnóstico, enquanto o tratamento foi o de restauração direta no caso de hipoplasia, onde 95,7% fizeram essa opção de tratamento.Conclusão: Ambos os grupos apesentaram dificuldade na tomada de decisão de tratamento nos dentes com amelogênese imperfeita e com fluorose dentária leve. Os discentes relataram possuir dificuldade no diagnóstico diferencial na prática clínica frente às diferentes lesões que acometem os tecidos dentários, além de terem pouco conhecimento sobre o diagnóstico das lesões abordadas.

Introduction: Biomarkers indicate levels of a particular chemical agent in the environment studied, which may be useful for monitoring health status, and nails may be major indicators of fluoride. Objective: To evaluate fluoride concentration in the fingernails of children as a biomarker for fluoride exposure. Methods: Twenty students were selected, aged 4-5 years old. Their nails were cut at 15 and 45 days (two collections), and the fluoride concentration in the nails was analyzed with the ion-specific electrode (Orion 9409) after rapid diffusion with HDMS. Results: The total fluoride mean of the samples was 3.68 μg F/g (sd 1.44), ranging from 1.39 μg F/g to 7.81 μg F/g. Eleven children (55%) brush their teeth three times a day, but only three children (15%) swallow toothpaste. Conclusion: There is a high prevalence of fluoride exposure in the fingernails of the children studied, presenting risk of developing dental fluorosis in permanent teeth.

Objective: This study aimed to verify the prevalence of psychoactive substances consumed by dentistry students, as well as to analyze the influence of sociodemographic variables and identify the level of life satisfaction among Dentistry students. Methods: It is a cross-sectional observational study including 159 students of an educational institution in a city of southern Brazil enrolled in the eight course periods. They were anonymously asked to a self-administered questionnaire regarding sociodemographic variables and use of psychoactive substances (PAS), questions were adapted by the validated instrument called Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), and the assessment of level of life satisfaction by the Satisfaction With Life Scale (SWLS). Results: The use of PAS at some point in life had prevalence of 90.6%. Alcohol was the most used PAS by students, followed by cannabis. The use of drugs for depression showed association with alcohol and cannabis consumption, cannabis was predominately consumed by male . The majority of students reported dissatisfaction with life. Conclusion: The prevalence of PAS use is high among the Dentistry students interviewed. The PAS most consumed by students was alcohol, followed by cannabis, psychoactive drugs, and tobacco.

The scope of this article is to analyze the relationship between satisfaction with quality of life, self-perception of oral health and experience with dental surgeons. The study is cross-sectional epidemiological in structure with a sample of 326 elderly individuals over 60 years of age living in a city in the north of the State of Rio Grande do Sul, Brazil. The instrument for data collection was a self-administered questionnaire with queries relating to self-perception in oral health (OHIP - Oral Health Impact Profile), Quality of Life Satisfaction scale and sociodemographic issues. The findings showed that the elderly with higher levels of quality of life satisfaction manifested an enhanced perception of their own oral health as well as a better perceived image of dental surgeons and less anxiety about their experiences with the dentist. It was proven that both the self-perception that the elderly have about oral health as well as their experience with dentists is associated with the quality of life satisfaction of the elderly. The results have important implications for decision-makers and formulators of public policy.

The objective of this article is to determine the frequency and severity of dental fluorosis, as well as to verify possible associations with dental caries, gender, age, ethnicity and geographic location of schools in schoolchildren of 12 years old and from 15 to 19 years in the city of Passo Fundo, Rio Grande do Sul State, Brazil. A total of 633 schoolchildren of both genders at the cited ages, enrolled in 26 public schools of fundamental teaching were involved in the epidemiological study. The inspection was performed by three examiners previously trained to apply Dean's Index. The prevalence of dental fluorosis in the studied group was of 32.8%. Predominant degree was the very light (78.4%), followed by light (11.1%), questionable (8.7%) and moderate (1.9%). The prevalence of dental fluorosis was expressive in this population, however, with a low degree of severity. Factors such as age and dental caries index showed to be related to the variable response.
