摘要 目的评价几种根管充填技术对根管再治疗术的影响。方法在该院进行根管再治疗术的152例患者的204颗单根管患牙作为研究对象,将204颗患牙的根管充填物完全去除后,按随机数字表法分为热垂直加压技术组(VC组)、常温流动牙胶充填技术组(GF组)、冷牙胶侧压技术组(LC组),分析根管再治疗术的2年治愈率和根尖周指数(PAI)情况。结果(1)2年治愈率:VC组为64%(46/72),显著高于GF组[56%(45/80)]和LC组[41%(21/52)]。(2)PAI为2~5级,2级112颗,3级44颗,4级21颗;5级27颗。2级以VC组和GF组居多(81%);3级以GF组和LC组居多(72%);5级以LC组居多(48%)。结论采用热垂直加压技术,根管再治疗的2年治愈率高,PAI高,其次可用常温流动牙胶充填技术。
