摘要 目的研究老年人慢性根尖周炎的疗效及该病评定指标的应用。方法对46例患慢性根尖周炎的老年人在接受根管治疗或牙髓塑化治疗2~9年后的58颗牙进行了复查;以同期治疗的40例青年人的50颗同类牙作为对照复查。采用根尖周指数(periapicalindex,PAI)评定X线片并结合临床检查,对其疗效进行评价。结果两组总疗效间差异无显著性(P>005),但治疗后4年以上的治愈率相比,老年组(580%)却明显低于青年组(871%)(P<005)。结论老年组慢性根尖周炎的远期疗效较青年组为差。作者认为PAI系统对评定根尖周病疗效具有良好的准确性、可重复性和对不同病情人群之间的分辨能力,值得推广应用。 Objective To study of the curative effect of teeth with chronic apical periodontitis in elderly people and the usage of assessment index. Methods Fifty eight teeth from 49 elderly and 50 teeth from 40 young patients were reexamined, which had received root canal therapy or resinifying therapy 2 to 9 years ago. The curative effects were evaluated based on clinical examination and radiographic assessment using periapical index (PAI).Results Statistically no significant difference for the overall healing rates between the two groups. But when the reexamination period was longer than 4 years, the healing rates in clderly people (58.0%) were significantly lower than those of the young people (87.1%). The treatment method and the size of the periapical lesion had significant influence on the results of the elderly people, whereas no influence on the young patients. According to our data, deep periodontal pocket and occlusal trauma were the main reasons of failure. Conclusion The long term curative effects of teeth with chronic apical periodotitis in elderly is lower than that of the young people. The PAI system is worth of utilizing popularly in the clinical dentistry.
