The aim is to evaluate the fracture resistance of endodontically treated teeth restored with posterior direct composite (PRC) resin, bulk-fill composite resin, dual-cure composite (DCC) resin, and short fiber-reinforced composite (SFC) resin material. Materials and methods: Ninety sound maxillary premolar teeth were divided into 6 groups which comprised 15 teeth each. Group I was a negative control group where neither cavity preparation nor root canal treatment was done on the specimen. Group II was named positive control group as it was left unrestored after mesio-occluso-distal (MOD) preparation and root canal treatment. Groups III to VI were filled with PRC, bulk-fill composite, DCC, and SFC, respectively, and subjected to fracture testing in a universal testing machine. Results: After statistical analysis, it was seen that group VI had increased mean fracture resistance as compared to other groups. Conclusion: It was concluded that short fiber-reinforced composite proved to have superior properties that other experimental groups and hence can be used as a core build-up material. Clinical significance: The core build-up is requisite as the residual tooth structure after endodontic procedure decreases and core build-up supplements the resistance and retention of the tooth structure.
