摘要
目的探讨残根残冠经根管治疗与冠修复后的临床治疗效果。方法选择2001~2005年在门诊收治的137颗残根残冠为研究对象,经根管治疗后行桩核冠修复,随访观察6个月~4年,分析其临床疗效。结果经6个月~4年随访,137颗患牙中122颗修复成功,8颗牙根出现不同程度的松动,4颗出现龈瘘,1例核桩因继发龋脱落;2例因牙周炎拔牙。结论在严格选择适应证的前提下,残根残冠经完善根管治疗与冠修复后可达到满意的临床治疗效果。
Objective To evaluate the clinical effects of residual crowns and roots restored with post-core crowns after root canal treatment. Methods A total of 137 residual crowns and roots were included in this study. Root canal treatment was first conducted and then post-core crowns were fabricated in all the cases. The follow- up period was from 6 months to 4 years , and clinical effects were evaluated. Results 122 cases succeeded. The roots were loose in 8 cases; apical infection appeared in 4 cases ; 1 post-core was lost because of secondary caries ; 2 roots were extracted due to serious periodontal disease.
