目的:探讨注射式热塑牙胶根管充填技术治疗根尖周病效果。方法:对我科收治的166例(248颗牙)根尖牙髓周病患者随机分为Ⅰ组与Ⅱ组,Ⅰ组82例(113颗牙)采取热牙胶垂直加压治疗,Ⅱ组84例(135颗牙)采取注射式热塑牙胶根管充填技术,观察并分析两组治疗效果。结果:对166例患者展开随访,Ⅰ组成功率达92.92%,ⅠI组成功率高达99.26%。结论:热牙胶垂直加压技术与注射式热塑牙胶根管充填技术对治疗牙髓根尖周病具有显著效果。相对来说,注射式热塑牙胶根管充填技术效果更加,成功率更高。
Objective: To investigate the effect of injectable thermoplastic gel root canal filling technique on periapical periodontal disease. Methods: A total of 166 patients (248 teeth) with periapical periodontitis treated in our department were randomly divided into group Ⅰ and group Ⅱ, group Ⅰ (82 teeth (113 teeth) Eighty-four cases (135 teeth) were treated with injection-type thermoplastic gel root canal filling technique. The therapeutic effects were observed and analyzed. Results: A total of 166 patients were followed up. The success rate of group Ⅰ was 92.92%, and the success rate of group ⅠI was as high as 99.26%. Conclusion: The application of hot teethers vertical compression technology and injection-type thermoplastic gel root canal filling technology have significant effect on the treatment of apical periodontal disease. In contrast, injection-type thermoplastic resin root canal filling technology more effective, higher success rate.
