Summary

The purpose of the 12-month clinical study was to evaluate and compare preheated, sonic-activated, and flowable composite resins used in Class V restorations.

Detailed description

Because of their superior aesthetics, minimal preparation needs, and capacity to adhere to tooth structure, resin composite materials are now frequently utilized in restorative dentistry. Materials with superior mechanical qualities, better handling qualities, and improved clinical performance have been developed as a result of ongoing advancements in composite technology. Viscosity-modulated composite resins have drawn a lot of interest among these developments because they seek to maximize cavity wall adaptability while preserving adequate strength and wear resistance. To enhance the therapeutic performance of composite resins, various methods have been developed to alter their viscosity. One method for improving flow and adaptability to cavity walls prior to polymerization is preheating composite resins, which momentarily lowers viscosity. Sonic-activated composite methods reduce viscosity during installation by using sonic energy, which makes cavity adaption and handling easier. Moreover, highly filled flowable composite resins have been created to increase their mechanical strength in comparison to traditional flowable composites by combining the better flow properties of flowable materials with increased filler content. Thus, the goal of this study was to assess the clinical performance of flowable composite resins that are warmed, sonic-activated, and highly filled when employed in Class V cavities.
