Summary

Endodontic treatment is performed frequently which often results in weakening of tooth structure. Coronal restoration is done to restore these endodontically treated teeth. Posts have been used to retain the coronal restoration and reinforce these teeth but unfortunately posts placement results in further weakening of tooth structure. Newer contemporary core buildup materials will be used to restore coronal part of tooth without using endodontic posts and then the fracture resistance of these teeth will be evaluated.

This study will be performed to evaluate the fracture resistance of endodontically treated teeth restored with newer contemporary core buildup materials.

80 recently extracted single rooted caries-free and unrestored premolars will be taken and mounted in acrylic resin blocks. Roots of teeth will be covered with light bodies of condensation silicone impression material to simulate periodontal ligaments. Class 1 and class 2 cavities will be prepared and endodontic treatment will be performed in these teeth specimens. Coronal restoration will be done with three core buildup materials (Cention-N, Zirconomer and Aristaloy Amalgam). Teeth specimens are then divided into group 1 and group 2 (class 1 cavity preparation and class 2 cavity preparation respectively) and each group is further divided into four subgroups: Subgroup A: Control group Subgroup B: Cavities restored with Zirconomer (Shofu) Subgroup C: Cavities restored with Cention-N (Ivoclar vivodent) Subgroup D: Cavities restored with Aristaloy Amalgam (Cookson) Fracture resistance of endodontically treated teeth restored with different core buildup materials will be tested by the Universal testing machine.
