无机三氧化物聚合物根尖段根管充填与倒充填治疗慢性根尖周炎的疗效比较

Efficacy Comparison of Retrograde Filling and Apical Root Canal Filling with Mineral Trioxide Aggregate for Chronic Apical Periodontitis

目的:比较应用无机三氧化物聚合物(mineral trioxide aggregate,MTA)在显微镜下进行根尖段根管充填与倒充填治疗慢性根尖周炎的疗效。方法:对慢性根尖周炎患者107例共130颗患牙进行治疗,根据MTA在根尖段充填方式的不同将其分为2组:根尖段根管充填MTA组(n=58)和根尖倒充填MTA组(n=72)。随访2年,通过临床症状和X线片检查评价疗效。结果:根尖段根管充填MTA组成功率为82.76%,根尖倒充填MTA组成功率为90.28%,2组成功率无显著差异(P>0.05)。结论:采用MTA根尖段根管充填与倒充填的方法治疗慢性根尖周炎均能获得较好的疗效。

Objective： To compare the effects of apical root canal filling and retrograde filling with mineral trioxide aggregate（MTA） for chronic apical periodontitis. Methods： A total of 130 teeth from 107 patients with chronic apical periodontitis were divided into two groups： Group A, apical root canal filling with MTA （n = 58） ; Group B, retrograde filling with MTA （n = 72）. The effects were e valuated by clinical and radiographic check-up after two years. Results： There was no significant difference between the success rate of Group A（82. 76 % ） and Group B （90.28 %）. Conclusions.. Both apical root canal filling and retrograde filling with MTA have good cura rive effects for chronic apical periodontitis.
