Abstract: 目的 探讨玻璃纤维桩在年轻恒牙冠折再接中的的应用价值. 方法 采用随机数字表将83例(103牙)年轻恒牙冠折患者分为两组,均行永久性根充和桩核冠系统修复.其中对照组41例(53牙)采用传统铸造镍铬合金桩核系统,观察组42例(50牙)采用高强度锥形玻璃纤维桩核系统. 结果 对照组和观察组的最终随访时间分别为(18.3±3.2)个月和(18.5±3.0)个月,差异无统计学意义(P>0.05).至末次随访,观察组成功率94.0%,对照组成功率81.1%,观察组明显高于对照组(P<0.05);此外,观察组在牙体形态、颜色和咬合功能方面的满意度均高于对照组(P<0.05). 结论 玻璃纤维桩在年轻恒牙冠折再接中的应用价值优于传统铸造金属桩.
