摘要
目的观察前牙残根玻璃纤维桩核修复的效果。方法选择120颗经过根管治疗的前牙残根,随机分为玻璃纤维桩修复组、预成合金桩修复组,各60颗患牙,随访3年,观察两组桩核脱落、折断及根折情况。结果玻璃纤维桩修复组桩核折断1例,桩核无脱落和根折;预成合金桩修复组桩核脱落6例,根折5例,两组桩核脱落率和根折率比较,差异有显著性(P=0.018、0.035)。结论玻璃纤维桩是一种较好的桩核修复体。
Obejctive To evaluate the clinical efficacy of glass fiber post in the restoration ot endodontically treated teeth. Methods This study consisted of 120 residual roots （canal therapy had been done before）, which were evenly randomized to fiber post group and alloy-dowel group. The falling off, fracture and root fracture of the teeth were investigated during three-year follow-up. Results Fracture of the core was noted in one case in fiber-post group, and six with core falling off, and five with root fracture were seen in alloy-dowel group, the differences between the two groups were significant （P = 0.018,0. 035）. Conclusion Glass-fiber post is a good dental prosthetic restoration for post and core.
