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 ( < 0.05). The mean difference of fracture resistance was significant ( > 0.05).
CONCLUSION
Composite resin possesses highest fractures resistance as compared to GIC and silver amalgam.
目的
本研究的目的是比较用玻璃离子水门汀、汞合金和复合树脂水门汀修复的根管治疗牙齿的抗折性。
材料与方法
40颗牙齿分为4组，每组10颗。第一组牙齿用银汞合金修复。第二组牙齿用玻璃离子水门汀修复。第三组牙齿用复合树脂修复，第四组牙齿为对照组，未进行任何处理。测试机对牙齿施加力以检测抗折性。
结果
第四组的平均抗折性最高（1050.2N），其次是第三组（956.2N）、第一组（836.4N）和第二组（766.4N）。差异具有统计学意义（<0.05）。抗折性的平均差异具有显著性（>0.05）。
结论
与玻璃离子水门汀和银汞合金相比，复合树脂具有最高的抗折性。
