| Summary: | Aim:
The primary objective of this study was to compare and evaluate the fracture resistance of class V composite restorations under multiaxial loading that were reinforced with Ribbond, Interlig, and GC everX Flow.
Materials and Methods:
Thirty-two freshly extracted maxillary premolars were randomly assigned to four groups of eight teeth each. Cavities were prepared in the cervical region. Group 1 received Ribbond, Group 2 received Interlig™, and Group 3 received GC EverX Flow™ in the cavity floor, followed by composite restoration. Group 4 had regular resin composites with no reinforcement. The teeth were then tested under multiaxial loading in a universal testing machine, and fracture values were recorded.
Results:
Statistical analysis was done using one-way ANOVA and Tuckey’s post hoc test. Statistical significance was set at P value < 0.05. GC everX Flow showed the highest fracture resistance, followed by other groups.
Conclusion:
Within the limitations of this study, it can be concluded that the class V cavities restored with reinforced composites considerably increased the fracture resistance of the restored teeth. In a descending order, GC everX flow, Ribbond, and Interlig are effective in reinforcing the class V cavities restored with composites. |
