摘　　要：目的通过对临床上感染根管的治疗,比较逐步深入法与逐步后退法的疗效,从而为临床上感染根管的治疗提供参考。方法将临床感染根管治疗病例368例,随机分为两组:试验组用逐步深入法预备根管;对照组组用逐步后退法预备根管。根管治疗完成后随访6～8个月,应用SAS6.12统计软件包对数据进行处理,统计方法为卡方检验。结果统计学分析表明:对于弯曲根管和狭窄根管,试验组治愈率明显高于对照组;对于普通根管,两组治愈率无差异;术后疼痛,试验组明显低于对照组。结论逐步深入法在感染根管治疗中优于传统逐步后退法。Objective To provide refrence for the treatment on the infected root canal through the comparison on the clinical effect between the step-down technique and step-back technique.Methods 368 cases were devided into two groups randomly.188 cases were prepared by the step-down technique(P group)while180 cases were prepared by the step-back technique(S group).The effects were recorded after the treatment for 6-8 months,chi-square test was used for data analysis;the results were assessed by SAS 6.12 software package.Results The curative rate of P group is higher than that of S group for the curving and strait root canals;There is no difference between the two groups for normal root canals;P group is significantly better than S group for the incidence and degree of the post-operative pain.Conclution The step-down technique is better than the step-back technique.
