老年人磨牙牙髓塑化治疗的临床疗效分析

目的评价老年人牙髓塑化治疗慢性根尖周炎的疗效。方法对76例(78颗磨牙)慢性根尖周炎的老年病例进行常规根管治疗、变异法根管治疗或牙髓塑化治疗,2年后进行复查;并以同期治疗的79例(80颗磨牙)青年病例同类治疗作对照。采用根尖周指数(periapical index,PAI)评定X线片并结合临床检查,对疗效进行评价。结果变异根管治疗法组与常规根管治疗组疗效差异无显著性(P>0.05),牙髓塑化治疗组与常规根管治疗组疗效差异有显著性(P<0.05)。结论牙髓塑化治疗用于治疗老年人慢性根尖周炎的远期疗效(70.83%)是肯定的。对老年人磨牙慢性根尖周炎按照不同的根管形态应采用不同的方法治疗。

Analysis of clinical curative effects of molar teeth in elderly people after resinifying therapy

Objective To study the curative effects of molar teeth in elderly people after using resinifying therapy.Method 78 teeth from 76 elderly and 80 teeth from 79 young patients were reexamined,which received root canal treatment,variation root canal treatment(rough canal:root canal treatment;fine canal:resinifying therapy) or resinifying therapy 2 years ago.The curative effects were evaluated based on clinical examination and radiographic assessment using periapical index(PAI).Results There were no statistically significant differences for the overall healing rates between the first two groups(P>0.05).Statistically significant differences were found for the overall healing rates between the first group and the last group(P<0.05).Conclusion The long-term curative effects of resinifying therapy on teeth with chronic apical periodontitis in elderly people were positive.Using different treatments according to root morphology in elderly molar teeth was reasonable.
