【摘要】：目的:研究不同方法去除直根管和弯曲根管内氢氧化钙封药的差异。方法:建立直根管、弯曲根管的体外标准化模型,用根管锉、超声冲洗器械、EndoActivator配合注射器冲洗去除根管内氢氧化钙封药,随后打开模型,体视显微镜下拍照,软件测量,计算氢氧化钙残余量并进行统计分析。结果:不同方法去除氢氧化钙能力:直根管中K锉≈EndoActivator≈P5直接冲洗;弯曲根管中EndoActivator≈预弯P5P5预弯K锉K锉直接冲洗。弯曲根管与直根管之间,K锉组、P5组、EndoActivaor组之间均有显著差异(P0.05)。结论:3种方法均不能完全去除根管内氢氧化钙,EndoActivaor是去除根管内氢氧化钙的较好方法。
[Abstract]:Objective: to study the difference of calcium hydroxide seal between straight root canal and curved root canal by different methods. Methods: to establish a standardized model of straight root canal and curved root canal in vitro, and to use root canal file. Endo Activator combined with syringe to remove calcium hydroxide seal in root canal, then opened the model, photographed under stereoscopic microscope, and measured by software. The residual amount of calcium hydroxide was calculated and analyzed. Results: the ability of removing calcium hydroxide by different methods: K file 鈮，
