ProTaper锉预备S形模拟根管偏移产生的连续观察
Continuous observation of canal transportation in S-shaped simulated root canal prepared by hand-used ProTaper
摘要
目的连续观察在ProTaper各号锉成形S形树脂模拟根管中根管偏移的形成过程。方法选用15个S形树脂模拟根管分别用手用ProTaper的各号锉按使用说明书进行预备,采集并储存Sl、S2、Fl、F2和F3预备完后的根管图像。结果 ProTaper各号锉对根管弯曲的凹侧壁过度切削,而对弯曲凸侧壁仅Sl、S2号器械有切削。结论手用Pro-Taper锉预备S形树脂模拟根管,对根管内侧壁的切削非常不均匀。
