摘要
目的 研究老年人根管治疗疗效及其影响因素。方法 对 5 6例 6 5岁以上老年人在根管治疗后 2年以上的 12 6颗牙齿进行检查 ,按治疗年限分三组 ,2～ 3年组 ,4～ 5年组以及 6年以上组 ,应用根尖周指数 (Periapicalindex)评定X线片并综合临床检查 ,对其疗效进行评价。结果 老年人根管治疗成功率为 72 .2 % ;三组间根管治疗成功率无显著性差异。恰填根管治疗的成功率 ( 82 .2 % )比欠填和超填的的成功率 ( 4 7.2 % )要高 ;恰填病例中 ,冠方修复体质量好的患牙比质量差的患牙根尖周炎发病率低 ( 2 5 .7%和 5 8.4 % ) ;去除欠填和超填病例后 ,桩冠修复患牙的根管治疗成功率为 5 8.8% ,而未做桩冠修复的患牙成功率为 87.5 %。结论 根充质量、冠方修复体质量。
Objective To study the curative effect of root canal therapy in elderly people and the influence of the curative effect.Methods One hundred and twenty-six teeth from 56 elderly people were examined which had received root canal therapy over 2 years.The teeth were divided into 3 groups according to curing time,2～3 years group,4～5 years group and over 6 years group.The curative effects were evaluated based on radiographic assessment by using periapical index (PAI) and clinical examination.Results The successful rate of root canal therapy in elderly people was 72.2% .There were no significant difference among the 3 groups in the successful rate of root canal therapy .Root canal treated teeth with adequate root canal obturation had a higher successful rate than teeth with inadequate obturation ( 82.2% vs 47.2% P< 0.05 ).Adequate coronal restoration were associated with lower incidence of apical periodontitis than inadequate restorations ( 25.7% VS 58.4% P< 0.05 ) in adequate root canal obturation cases.The successful rate of root canal therapy in post crown teeth was 58.8% and 87.5% in the teeth without post crown treatment except the inadequate obturation cases (P< 0.05 ).Conclusion The quality of root filling?coronal restoration and post crown can influence the curative effect of root canal therapy in elderly people.
