Introduction Pit and fissure caries account for about 90% of caries in children and adolescents. Sealant application may be a preventive conservative approach. But it's still challenging to bolster the retention of the filled sealant and to chop back the microleakage. Aim Aim is to evaluate and compare the microleakage and shear bond strength (SBS) of three filled pit and fissure sealants (PFS) using a subpressure and adhesive system: an experimental analysis. Materials and methods A total of 90 orthodontically extracted premolars were prepared for microleakage and SBS and divided according to materials and subgroups. Group I: resin-based filled PFS, group II: resin-modified glass ionomer-based filled PFS, and group III: giomer-based filled PFS. Subgroup 1: only sealant application, subgroup 2: subpressure application, and subgroup 3: adhesive system + subpressure application. Samples were subjected to thermocycling. Microleakage was assessed with a dye penetration method under a stereomicroscope, and SBS was assessed with a universal testing machine. Statistical analysis and results Unpaired t -test and one-way analysis of variance (ANOVA) test were used for analysis. Significant when p < 0.05. The SBS showed significant results for subpressure application and giomer-based filled PFS with p < 0.05. The microleakages score differed significantly for the subpressure application group with p < 0.05. Giomer-based filled PFS showed the least microleakage score. Conclusion This study concluded that giomer-based filled PFS showed statistically significant results. The subpressure technique significantly reduces microleakage and increases SBS.

Background: Pit and fissure caries account for about 90% of the caries of permanent posterior teeth and 44% of caries within the first teeth in children and adolescents. Sealant application may be a preventive conservative approach. However, it is still challenging to bolster the retention of the filled sealant and to chop back the microleakage. Aims and Objectives: To evaluate and compare the depth of resin tags of three filled pit and fissure sealants (PFS) using subpressure and adhesive system under scanning electron microscope (SEM). Materials and Methods: This study was in vitro experimental study. Forty-five orthodontically extracted premolars were prepared for resin tag depth measurement and divided according to materials and subgroups. Group A- Resin-based filled PFS, Group B- Resin modified glass ionomer-based filled PFS, Group C- Giomer based filled PFS. Subgroup 1- Only sealant application, Subgroup 2- Subpressure application, Subgroup 3-Adhesive system + Subpressure application. Samples were subjected to thermocycling. The sectioned tooth fragments were polished using a carbide stone and then mounted under SEM for analysis. Photographs of the sections were obtained and the resin tag lengths were measured. Unpaired t-test and one-way analysis of variance test used for analysis. Results were considered significant when P<0.05. Results: The depth of resin tags of the tested materials differed significantly for Giomer-based and resin-modified glass ionomer-based filled PFS group with P<0.05. Whereas Resin-based filled PFS group was not found significant P>0.05 for the depth of resin tags. Conclusion: This study concludes that Giomer based filled PFS group and Resin-modified glass ionomer-based filled PFSs showed the highest Resin tag depth respectively when compared with Resin-based filled PFSs. The Subpressure application group was more effective followed by Adhesive+subpressure application group and Control group.

Aim Composite restorations often have gingival margins near the cemento-enamel junction (CEJ), where the microleakage of these margins can significantly contribute to the restoration failure, especially in the cervical lesions. It is important to determine the microleakage is crucial, as it typically occurs through the interfacial gap between the tooth and the restoration. Various resin composites and techniques have been developed to minimize this gap and reduce the risk of microleakage. The aim of this in vitro study was to evaluate the levels of microleakage of different modes of a universal adhesive and two novel resin composites in restoring class V cavities in the central incisors. Methods Sixty-six freshly extracted sound human central incisors of the similar size were randomly assigned to 2 groups ( n = 33 per group) according to the brand of resin composite. Each group was further divided into 3 subgroups based on the Scotch Bond Universal (3 M ESPE, Saint Paul, MN, USA) application protocol used: (a) total etch, (b) self-etch and (c) selective etch. After composite restoration completed with Omnichroma (Tokuyama Dental Corp., Tokyo, Japan) and Filtek Universal Restorative (3 M ESPE, Saint Paul, MN, USA), each tooth was immersed in a 0.5% basic fuchsin dye solution at 37C 0 for 24 h. After dye penetration, teeth were sectioned and evaluated with conventional (scoring) and digital methods (ImageJ). The intra- and inter-examiner agreement was estimated according to the Kappa statistics and the results were analyzed with the one-way ANNOVA and the Kruskal–Wallis test ( p < 0.05). Results The rates of microleakage of the gingival and incisal margins are statistically similar, regardless of the composite brand and the method of application of the universal adhesive. Conclusion The microleakage exhibited by current adhesives and resins is independent of the adhesive application mode and measurement method.
