Original Group

The aim of this study was to evaluate retention and efficacy of polyacid-modified composite resin used as fissure sealant (Variglass V.L.C.) after six years. Three-hundred and seventy permanent first molars were sealed. After six years, 42.0% of the original group was re-examined and the sealant was found to be totally present in 3.4%, partially present in 16.2% and absent in 70.4% of the previously sealed occlusal surfaces. During the 6 years period, 9.5% of the sealed surfaces became carious, 25.0% were filled and 65.5% remained sound. Although the retention rate of the material has been very low, it appears to have prevented dental caries in 2/3 of the teeth evaluated after six years of placement.

Pit And Fissure Sealant

Introdution: The occlusal surface of the molars are more susceptible to dental caries because of their anatomy, so in some cases, the sealants are indicated. Objective: The objective of this study was to evaluate the efficacy, retention, presence of caries and marginal discoloration of resinous sealants (Fluoroshield and Prevent) in first permanent molars. Methods: Ninety - one children aged 7 to 9 years were selected from a municipal institution Regente Feijó, SP, Brazil, for the application of resinous sealants to first permanent lower first molars. The application of Fluoroshield and Prevent resin sealants was performed according to the manufacturer's recommendations. The evaluation was performed after 6 and 12 months by double-blind examiners and followed the criteria: alpha (total sealant, absence of caries and absence of pigmentation) charlie (partial sealing, superficial caries and light pigmentation) charlie complete sealing, presence of cavitation and pigmentation) after 12 months of application by two previously calibrated examiners. Results: Using Fischer's exact test, no significant difference (p 0.05) was observed between the resin-based sealant groups. In the evaluated criteria, both sealants after three years were similar, and may therefore be suitable materials for sealing grooves and fissures in permanent molars.Descriptors: Pit and Fissure Sealants; Dental Caries; Dentition, Permanent; Oral Health.ReferencesPalma-Dibb RG, Chinelatti MA, Souza-Zaroni WC.

Abstract Background Dental caries is a significant public health problem in Iran. Teaching  minimally invasive interventions in paediatric dentistry may facilitate the provision of treatment for untreated dental caries in children. We evaluated the teaching of such interventions in both undergraduate dental curriculum and Paediatric Dentistry Specialty Training Programme (PDSTP) in Iran. Methods This was a cross-sectional questionnaire-based survey. Participants in this study were the directors of 40 undergraduate programmes and 15 PDSTPs in all Iranian dental schools (response rate = 100%). Descriptive statistics were reported. Results The most commonly taught methods were preventive fissure sealant and preventive resin restoration (PRR), which were taught ‘both didactically and clinically’ in all undergraduate dental programmes. The least commonly taught methods were silver diamine fluoride (SDF), the Hall technique and resin infiltration, which were taught ‘both didactically and clinically’ in less than 5% of dental schools. The same three methods were the least commonly approaches taught in PDSTP, further, they were less often perceived to be ‘essential’. Conclusions There was a notable variation in the teaching of the management of dental caries in Iran’s dental education. Some minimally invasive approaches including SDF, the Hall technique and resin infiltration are not being commonly taught in Iranian dental schools despite the evidence base for these techniques.

Resin Restorations

Background: Dental caries is a hard tissue disease caused by bacterial metabolic activity that causes demineralization, teeth that have caries should be filled in order to function again. One of the restorative materials closer to natural teeth is composite resin because it is the same colour as natural teeth and is easy to shape. As for the placement technique, bulkfill is also used because it is more time-efficient, and irradiation is accompanied by applying the restoration material in one batch. However, the bulkfill technique often causes micro-leakage of dental caries deposition. The intermediate layer is an intermediate layer used to prevent micro-leakage at the edges of the restoration as a base layer for restoration to create a good adaptation before applying packable composite resin. Therefore, bulkfill coating technique with the intermediate layer can reduce the risk of microleakage. Purpose: To describe the bulkfill technique with an intermediate layer against marginal adaptation with class II composite resin restorations. Review: The literature sources used in the preparation of the articles through several databases with descriptions. More journals say that micro-leakage in class II cavity deposition with the intermediate layer technique is better than the bulkfill technique because the intermediate layer technique has better bond strength than the bulkfill technique. If the Bulkfill technique is modified with the Intermediate layer technique, it can show good correlation and internal adaptation. Conclusion: Bulkfill technique with an intermediate layer against marginal adaptation with class II composite resin restorations can reduce the microleakage rate by reducing the polymerization's shrinkage strain.

The objective of this study was to evaluate the effects of an alcohol diet on Streptococcus of the mutans group and on dental caries in the oral cavity of rats. Forty animals were divided into 3 groups according to the following liquid diets: 20% ethanol solution (Alcohol Group, AG), 27% sucrose solution (Isocaloric Group, IG), and water (Control Group, CG). After 56 days, samples were collected and plated on Mitis Salivarius Bacitracin agar to assess the number of colony forming units (CFU/mL) of Streptococcus of the mutans group. The animals were sacrificed and the jaws were removed in order to assess the occurrence of dental caries on the smooth and occlusal surfaces using stereomicroscopy. The data were submitted to ANOVA and Tukey test. The average numbers of CFU/mL (10³) were: 8.17 (AG), 9.78 (IG), and 5.63 (CG). There was no significant difference among the groups for the occurrence of occlusal caries. Regarding smooth surface caries, in the upper jaw, the caries number in the IG (1.58) was similar to that in the AG (2.06) and in the CG (1.14), and the number of caries in the AG was higher than in the CG; in the lower jaw there was significant difference among the 3 groups: AG (1.14), IG (2.00) and CG (0.43). The diets with the alcohol and sucrose solutions presented a tendency of increasing the colonization by Streptococcus of the mutans group and of increasing the occurrence of smooth surface dental caries in rat molars when compared to the control diet.
