摘要
目的:比较手用不锈钢K型锉根管预备方法和机用镍钛P rofile根管预备方法对单根管前磨牙根管清洁能力的差异。方法:将5颗离体单根管前磨牙开髓、拔髓后分为5组,1组作为对照,不做任何处置,其余4组分别采用手用K型锉根管预备;手用K型锉根管预备并去除涂层;机用P rofile根管预备;机用P rofile根管预备并去除涂层。然后做扫描电镜观察并拍照记录结果。结果:机用镍钛P rofile比手用不锈钢K型锉的根管清理效果强,与辅助性的化学性根管预备相结合可达到最佳清洁效果。结论:机用镍钛P rofile加用EDTA对根管清洁能力最高。
Objective;To compare the cleanliness of the single root canal premolar walls prepared by stainless steel K file and profile rotatory device. Methods: Five extracted single canal premolars were randomly divided into five groups. One group was used as control. The rest four groups were prepared with K file and profile rotatory device with or without 15%AEDTA ,respectively. After that, the root canal was processed for SEM observation and photos were taken for the record results. Results: Profile rotatory device could produce cleaner root canal walls than the K file and would get the best cleaning effect combined with EDTA. Conclusions :The profile rotatory device added 15%EDTA gets the cleanest effect.
