Aim of study was to compare the clinical visual and radiographic diagnostic technique with histological analysis of early proximal carious lesions. Materials and method. Study group included 96 proximal surfaces (48 teeth obtained from dental extractions for orthodontic or periodontal reasons). The proximal surfaces were examined by visual clinical examen and radiographic examen. A histological assessment was performed as gold standard. The sensivity and specificity values were calculated for clinical and radiographic examen. The values were analysed using McNemar test, with significance threshold p < 0.05. Results. Significant statistical differences were obtained when comparing both the sensitivity and specificity of the radiological detection method compared to the clinical method (p=0.0001

Aims of study. The aims of study were as follows: assessment of esthetic, functional and biological FDI indices of posterior composite restorations; assessment of decisions for non-intervention vs. repair/replacement of the posterior composite restorations. Materials and method. The retrospective study was performed on a study group of 69 patients (mean age: 25.31± 4,45 yrs; gender: 36 males, 33 females) that were treated for various dental pathologies in Odontology-Periodontology, Fixed Restorations of Clinical Learning Base of Faculty of Dental Medicine, U.M.F. Grigore T.Popa Iași (Romania) with a total number of 309 posterior composite restorations (class I and II Black) aged 3-5 yrs. The composite restorations were clinically evaluated using visual-tactile method. The evaluations were carried out during the recall session by an independent examiner, according to the FDI criteria (esthetic, functional, biological). The frequency of non-intervention versus repair/replacement decision was assessed globally and related to the parameters of the study group (gender, cariogenic risk, cavity design, arch/dental group location). Statistical analysis was performed in SPSS 29.0. Quantitative variables were characterized by descriptive statistics (means and standard deviations). Results. In the study group, 38,8% of all composite resin restorations required repair or replacement (FDI scores 4-5). The decisions of repair/replacement related to the assessed variables were as follows: 22,4% (Class I) vs 54,2% (Class II); 30,6% (males) vs 31% (females); 42,9% (high cariogenic risk) vs 20,4% (low cariogenic risk); 29,7% (Mx location) vs 31,5% (Md location); 41,4% (premolars) vs 49,5% (molars). Conclusions. 31% of posterior composite restorations aged 3-5 years require repair or replacement. Surface condition and margin discoloration are most frequent esthetic scores related to decisions of repair or replacement. Significantly higher percentages of Class II composite restorations (versus Class I) and molars restorations (versus premolars) were associated to requires repair or replacement. The most frequent biological score related to replacement decisions is the presence of secondary caries, mostly in Class II restorations.

Resin composites are the first choice for direct restoration of posterior teeth in the treatment of dental caries. This article reviews factors that influence the clinical performance of composite restorations and the results of clinical trials assessing longevity of posterior resin composite restorations. Materials and method. PubMed, and Web of Science electronic databases were searched for articles investigating the clinical performance of direct resin composite restorations placed in posterior teeth. Results and discussions. Factors with significant influence on longevity of posterior composite restorations include patient-related factors (age, carious risk, periodontal disease, bruxism), dental group, cavity size and volume, cervical margin extension, root-filled teeth, oclusal stress. Conclusions. Dental resin composites are material of choice for use in direct minimal interventions in posterior teeth. For patients without bruxism, in medium size cavities, direct composite resins demonstrate similar clinical performance with amalgam restorations. The clinical performance of restorations depends on a number of factors including variables related to the restored tooth, the materials and techniques employed, the patient’s risks, and professional clinical decisions.

Tobacco smoke contains a variety of harmful chemicals such as tar, benzopyrene, formaldehyde and hydrogen cyanide. These substances can affect both the quality and quantity of saliva, thus disrupting remineralization processes. Smoking can have a significant impact on the inorganic component of saliva and, consequently, can affect its viscosity and degree of mineralization.The aim of this study was to evaluate the impact of smoking and the correlations of some cariogenic risk parameters such as DMFT Index, resting and stimulated salivary flow rate, salivary pH and buffer capacity and micro-crystallization index in smokers using classic and electronic cigarettes. Material and method:The study was performed on 50 patients from the Clinical Base of the Faculty of Dental Medicine, “Grigore T. Popa” University of Iași, Romania with a medium number of carious lesions and a medium carious risk. The patients aged between 19 and 35 years, were divided into five groups (n=10): I – non-smokers, II – light smokers (1-10 classic cigarettes/day), III – moderate smokers (10-20 classic cigarettes/day), IV – high consumption (over 20 classic cigarettes/day) and V – electronic cigarette smokers. Results showed that the DMFT index values were very low in non-smokers while the highest values were reached by the electronic cigarettes users. Regarding the resting and stimulated salivary flow rate, the values decreased significantly in classic cigarettes medium and high consumers and in electronic cigarettes users when compared to non-smokers. When analyzing the pH and buffer capacity values it can be observed that smoking more than 10 cigarettes per day or the use electronic cigarettes can significantly reduce the values. The micro-crystallization index is also reduced in electronic cigarettes smokers or in medium or high classic cigarettes consumers. Conclusions: Consumption of more than 10 classic cigarettes per day or electronic cigarette affects the resting and stimulated salivary flow rate, the salivary pH value, the buffer capacity and the micro-crystallization index. E-cigarette users or smokers of more than 20 cigarettes per day are associated with an increased number of decayed, missing or filled teeth.

This article explores the impact of Sjögren's syndrome on saliva and its correlation with dental caries. Sjögren's syndrome is an autoimmune disease that affects saliva production and composition, increasing the risk of dental caries. The study found significant differences in dental and salivary health between patients with Sjögren's syndrome and a control group. It emphasizes the importance of oral hygiene and following dentist recommendations for caries prevention and treatment for individuals with Sjögren's syndrome. The document is a comprehensive list of references and citations related to Sjögren's syndrome and oral health, providing a thorough overview of current research on the topic.

The study aimed to determine prevalence of incipient occlusal caries related to different cariogenic risk categories as well as the distribution of incipient occlusal caries accordingly to ICDAS classification and results of laserfluorescence examen. Material and methods. The study group included patients classified in low cariogenic risk (18 patients, 320 occlusal surfaces), medium cariogenic risk (65 patients, 320 occlusal surfaces) and high cariogenic risk (32 patients, 527 occlusal surfaces). 1960 occlusal surfaces were assessed using clinical examen (ICDAS system) and laserfluorescence method (DIAGNODENT, Kavo). Results. For the category of low cariogenic risk patients, most incipient occlusal caries are classified as code ICDAS 02 (11.56%) and 13.43% are recorded in the range of values 10-20 (enamel caries) accordingly to laserfluorescence examen. The patients with medium cariogenic risk present similar rates of incipient occlusal caries with codes ICDAS 02 (13,74%) and 03 (13,56%), as well as 20,20% occlusal surfaces recorded with values 10-20 in laserfluorescence method. The patients with high cariogenic risk present similar rates of incipient occlusal caries with codes ICDAS 02 (15,55%) and 03 (13,66%), as well as 18,78% occlusal surfaces recorded with values 10-20 (enamel caries) and 14,23% (dentinal caries) with values over 30, in laserfluorescence method. Conclusions. The rates of incipient occlusal caries, accordingly to ICDAS system and laserfluorescence examen, are also influenced by cariogenic risk category.
