Abstract

The aim of this study is to evaluate the fracture resistance and failure mode of endodontically treated teeth (ETT) restored with different composite materials. A total of 40 mandibular first molars were selected and divided into four groups (n = 10). Group I was control group, Group II samples were restored with glass fiber post combined with convention Filtek Z 350, Group III samples were restored with bulk-fill composite resin, and Group IV samples were restored with polyethylene reinforced fiber with alternate layers of conventional composite. The samples were subjected to fracture strength testing until failure. The compressive strength and the failure mode were recorded. Statistical analysis was performed using one-way analysis of variance. A statistically significant difference was found in the fracture resistance between the four groups with the highest fracture resistance in the control group followed by Group II samples restored with bulk-fill composite, then Group III samples restored with glass fiber post and conventional composite, and then Group IV samples restored with alternate layers of polyethylene fiber reinforced composite and conventional composite. It can be concluded that the use of bulk-fill composite for the restoration of ETT may be an alternative treatment modality as it provokes a more conservative and cost-effective treatment.
