Abstract

Background:  Endodontic teeth are more prone to get fractured. There are numerous restorative materials that possess different fracture resistance. The present study was conducted to compare the fracture resistance of endodontically treated teeth restored with Glass Ionomer Cement (GIC), amalgam and composite cements.  Materials & Methods: The present study was conducted on 40 freshly extracted mandibular premolars. All teeth were divided into 4 groups of 10 teeth each. Group I teeth were restored with silver amalgam. Group II teeth were restored with GIC. Group III teeth were restored with composite and group IV teeth were control in which no alteration was performed. Testing machine applied force on teeth to detect fracture resistance. Results: The mean fracture resistance was maximum in group IV (1050.2 N) followed by group III (956.2 N), group I (836.4 N) and group II (766.4 N). The difference was statistically significant (P< 0.05). The mean difference of fracture resistance was significant when all groups were compared (P< 0.05) except in group I and group II (P> 0.05).  Conclusion- Post restoration of endodontically treated teeth is essential to strengthen the teeth. Composite resin possesses highest fractures resistance as compared to GIC and silver amalgam.
