老年人磨牙根管治疗变异法的临床疗效分析

目的 :研究老年人变异根管治疗法治疗慢性根尖周炎的疗效。方法 :对 83例慢性根尖周炎的老年病例在接受常规根管治疗、变异法根管治疗或牙髓塑化治疗 2年后的 85个磨牙进行复查 ;并以同期治疗的 79例青年病例 82个同类牙作对照。采用根尖周指数 (periapicalindex ,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 .0 5 ) ,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 .0 5 )。结论 :变异根管治疗法治疗老年人慢性根尖周炎的远期疗效是肯定的。对老年人磨牙按照不同的根管形态采用不同的方法充填是合理的。

Analysis on clinical curative effects of molar teeth in elderly people after variation root canal treatment

Objective:To study the curative effects of molar teeth in elderly people after using variation root canal treatment. Method:85 teeth from 83 elderly and 82 teeth from 79 young patients were reexamined, which had 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). Result:There are no statistically significant difference for the overall healing rates between the first two groups (P>0.05). Statistically significant difference 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 variation root canal treatment to teeth with chronic apical periodontitis in elderly people were decided. Using different treatment according to root morphology in elderly molar teeth was reasonable.
