一次性根管治疗173颗患牙临床疗效观察

The observation of clinical therapeutic effect of one-time root canal therapy 173 diseased teeth

目的观察急慢性牙髓炎、无根尖症状的慢性根尖周炎行一次性根管治疗的临床疗效。方法选择2000—2005年于大连大学附属中山医院口腔科门诊就诊的急慢性牙髓炎、慢性根尖周炎患者患牙173颗,随机分成两组,分别进行一次性根管治疗与多次治疗,并于2年后复诊。通过X线和临床检查评价两组患牙愈合情况以及疗效上的差异。结果一次性根管治疗组的治愈率为92.86%,多次治疗组的治愈率为89.89%,χ2检验结果显示P>0.05,两组疗效差异无统计学意义。结论一次性根管治疗组的治愈率与多次治疗组差异并无统计学意义,可以认为一次性根管治疗与多次治疗的疗效相同,临床上可以广泛应用。

Objective To study the clinical therapeutic effect of one-time root canal therapy for acute,chronic pulpitis and periapical periodontitis which have no symptom of root tip.Methods Choose 173 teeth from the year of 2000 to 2005,with acute,chronic pulpitis and periapical periodontitis.These teeth were divided into two groups randomly.Group 1 was treated by one-time root canal therapy and Group 2 was treated by multi-visit root canal therapy.Then they were follow-up visited at 2 years and were evaluated according to X-ray film and clinical examination to reveal the difference of the two groups on their healing and curative effect.Results The curative ratio in group 1 was 92.86%,groups 2,89.89%.By χ2 test,P>0.05;there was no significant difference between the two groups.Conclusion There is no significant difference between the two groups on curative ratio,so there is no difference on treatment effect between two kinds of treatment methods.That shows one-time root canal therapy can be adopted extensively.
