Aim: This study aims to identify the prevalence of the use of rubber dam (RD) for isolation during resin composite restorations in a clinical scenario. It also aims to evaluate restorations done with and without RD for radiolucencies present postoperatively. Methods: A total of 50 voluntarily participating dentists were asked to do posterior composite restorations for primary caries lesions affecting the occluso-proximal surfaces. The isolation protocols followed were noted, and postoperative bitewing radiographs were evaluated independently by two investigators. The presence of radiolucencies between the tooth-restorative interface and in the body of the restoration was assessed and statistically evaluated using Chi-square test at a significance level of P ≤ 0.05. Results: The results showed that 71.5% of the restorations were not done under RD isolation. There was a statistically significant difference in the number of radiolucent areas seen in restorations done with and without RD. Conclusion: This study shows a low percentage of clinicians use RD for isolation during composite restorations. It also indicates that radiolucent areas are more often associated with restorations done without RD isolation. This study stresses that there is a need to change the clinician's convictions about isolation protocols followed during composite restorations.
Aim: To compare the shear bond strength of microhybrid and BulkFill composite, when they are placed under three different incremental curing techniques: gingival-occlusal layering (horizontal), wedge-shaped layering (oblique), and bulk technique.
Materials and methods:A flat dentinal surface of 60 teeth was prepared by removing 1.5 to 2.0 mm of their occlusal surfaces with the help of single-sided diamond disk for testing. These samples were randomly divided into two groups of 30 samples each: group I for microhybrid composite (Filtek Z250,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
