Objectives:
The objective of the study is to compare the fracture resistance of endodontic treated tooth restored with GIC, amalgam, and composite cements.
Materials And Methods:
Forty 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 (P > 0.05).
Conclusion:
Composite resin possesses highest fractures resistance as compared to GIC and silver amalgam.
