摘要
目的探讨根管治疗(root canal therapy,RCT)牙髓病及根尖周病的临床疗效。方法 989例(1 008颗患牙)牙髓病及根尖周病患者均行RCT治疗。分析根管充填质量,随访2年,观察RCT治疗失败的情况。结果①1 008颗患牙中,恰填783颗患牙,恰填率为77.68%;欠填177颗患牙,欠填率为17.56%;超填48颗患牙,超填率为4.76%。②前牙根管欠填率明显低于磨牙(P<0.01)。③随访2年,第1年RCT失败率为12.28%,第2年RCT失败率为15.29%。结论RCT治疗牙髓病及根尖周病的疗效显著。RCT的成败与牙位(牙齿类型与牙齿位置)、根管弯曲度及钙化度等有关。
Objective To explore the clinical curative effect of root canal therapy(RCT) to pulpitis and apical periodontitis.Methods Nine hundred ninety eight patients(1 008 teeth)with pulpitis and apical periodontitis were treated with RCT.Root canal filling quality and treatment period of these teeth were evaluated.Teeth of the total were followed up 2 years and 2-year success rate were evaluated.And to observe the failure factors in RCT.Results ①In 1 008 teeth,the number of adequate filling,underfilling,and overfilling were 783,177 and 48.The ratios of adequate filling,underfilling,and overfilling were 77.68%,17.56% and 4.76%,receptively.②Before the root canal filling was significantly less than molar(P〈0.01).③Following up 2 years,the failure rate is 12.28% in 1-year,the failure rate is 15.29% until 2-year.Conclusion The clinical curative effect of RCT to pulpitis and apical periodontitis is excellent.The numbers and morphological difference type of root canal,root curvature and calcification have significantly influenced outcome of RCT.
