摘　　要：目的:观察牙髓炎和根尖周炎根管治疗术中根充挡塑型预备对根管治疗术质量的影响。方法:根据根管治疗时常规预备和根尖区塑型预备随机分成对照组和实验组,查阅近年来门诊治疗的305颗牙临床记录资料和RVG数码成像系统中影像资料,将两组患牙根管预备的根充挡直径(根尖宽度)、恰填状况(根管工作长度和密度)及治疗后咬合疼痛各项指标进行对比分析。结果:牙髓炎和根尖周炎患牙根充挡直径经t检验,实验组大于对照组;经χ2检验,恰填率实验组高于对照组,治疗后咬合疼痛实验组低于对照组。两组比较均有统计学意义(P<0.05)。结论:预备根尖区时进一步塑型根充挡可以提高根管治疗质量,为良好预后奠定基础。评价根管治疗术的治疗质量还需结合远期随访中的客观检查包括咀嚼功能和影像学资料。Objective： To evaluate the association between the quality of the root canal therapy and root canal prep- aration of the apical width among patients with pulpitis and apical periodontitis. Methods： According to the routine preparation of root canal and cusp--shaping of root canal the experiment was randomized in experimental groups and control groups ,and recorded the clinical data and RVG digital imaging of out--patient of 305 teeth. Baseline charac- teristics of the apical width ,appropriate filling and occlusal pain were comparable in two groups. Results： There was a significant difference that apical width of experimental groups was higher than that one of control groups by t test. With chi square statistics, proper filling in experimental groups was higher than control groups , Oeclusal pain after treatment of experimental groups was lower than that one of the control groups. There were statistically significant difference between experimental groups and control groups（P〈0.05）. Conclusion： Further shaping the apical width of root canal maybe enhance RCT as well as good prognosis. The evaluation of quality of the root canal therapy re quire long--term follow--up including the masticatory function and imaging data by the objective examination.
