摘要/Abstract

摘要： 目的:比较机用ProTaperNext和WaveOne在弯曲树脂模拟根管中的成形能力。方法:选取统一规格的透明树脂模拟根管40个,将其随机分为2组,分别使用ProTaperNext和WaveOne锉以冠向下技术预备两组树脂模拟根管。使用ImagePro Plus软件测量根管弯曲半径和弯曲度的变化以及各测量点去除树脂量,计算树脂去除总量和两组器械的中心定位力,同时记录和分析根管工作长度的变化和器械变形、分离等参数。结果:两种器械预备根管时,均能保持较好的工作长度,不易发生器械分离,能够较好的维持根管原始走形,但在根尖段,WaveOne预备后的根管较易发生偏移。结论:ProTaperNext与WaveOne相比,在预备重度弯曲根管时具有良好的根管成形能力。

Abstract: Objective: To compare the shaping ability of ProTaper Next and WaveOne in simulated resin root canals. Methods: Forty standard simulated resin root canals were randomly assigned to two groups, one group for ProTaper Next and the other group for WaveOne with crown-down techniques. After preparation, the change of root canal arch radius and curvature and the amount of resin removed at the inner and outer canal wall at different measuring points were measured with Image Pro Plus 5.0. The total amount of resin removed was also assessed. At the same time, change of working length and instruments failure were recorded. Results: Both instrument systems could well maintain the working length and original root canal shape. However, the canals prepared with WaveOne showed higher transportation at the apical part. Conclusion: Compared with WaveOne, ProTaper Next showed better shaping ability, especially in the apical part of severely curved canals.

Key words: ProTaper Next, WaveOne, Curved root canal, Shapingability
