Abstract
AIM
To compare the fracture resistance of teeth restored with fiber-reinforced composite (FRC) posts and experimental dentin posts milled from human root dentin.
MATERIALS AND METHODS
Thirty maxillary central incisors were divided into three groups of ten each. Twenty teeth were restored with FRC posts and solid dentin posts and numbered as Groups 2 and 3 respectively while Group 1 acted as the control, without any post. The teeth were loaded at 135° angle to their long axes after core build-up and the failure loads were recorded.
RESULTS
One-way Analysis of Variance (ANOVA) and Bonferroni multiple comparisons revealed a significant difference among test groups with the control group showing the highest fracture resistance, followed by the dentin post group and lastly the FRC post group.
CONCLUSIONS
Teeth restored with dentin posts exhibited better fracture resistance than those restored with FRC posts.
摘要
目的
比较用纤维增强复合材料（FRC）桩修复的牙齿与用人牙根质铣削而成的实验性牙本质桩修复的牙齿的抗折性。
材料与方法
30颗上颌中切牙分为三组，每组10颗。20颗牙齿分别用FRC桩和实心牙本质桩修复，分别编号为第2组和第3组，而第1组作为对照组，不使用任何桩。在核成形后，牙齿以与长轴成135°角加载，并记录破坏载荷。
结果
单因素方差分析（ANOVA）和Bonferroni多重比较显示，测试组之间存在显著差异，对照组的抗折性最高，其次是牙本质桩组，最后是FRC桩组。
结论
用牙本质桩修复的牙齿比用FRC桩修复的牙齿表现出更好的抗折性。
