Comparative Evaluation of Fracture Resistance of Teeth with Different Techniques Using Composites

Abstract

Background and Aim: The most aesthetically pleasing direct tooth-colored restorative material is composite. The advancement of resin-based composite technology has enhanced dental professionals' acceptance of this material, particularly for posterior teeth. The composite must be strong enough to withstand bulk fracture. We examined the fracture resistance of bulk-fill composites with a flowable liner below the bulk-fill in this study.

Materials and Methods: Twenty teeth were separated into two groups of ten in this in vitro investigation. Ideal class II cavities were restored; Group A with bulk-fill, and Group B with flowable composite below bulk-fill. A Universal Testing Machine was used to assess the fracture resistance of the teeth.

Results: The fracture resistance of the two groups differed significantly (p = 0.05). The mean value for Group A was 0.4870 kN and Group B was 0.6110 kN.

Conclusion: Within the study's limitations, it is determined that flowable composite beneath bulk-fill enhances tooth fracture resistance when compared to solely bulk-fill..
