2种机用镍钛器械磨牙根管预备效果的临床观察

Abstract

Abstract: Abstract：　Objective　 To compare the effects of molar root canal preparation using two kinds of rotary NiTi instrumrnts. Reciproc and Mtwo instruments. Methods　 A total of 62 patients were enrolled in this study. The patients' molars needed root canal treatment because of pulpitis or periapital periodontitis. And the patients were randomly divided into Group R[Reciproc group(32 cases)]and Group M[ Mtwo group(30 cases)].The above two groups were filled with warm qutta-percha vertical condensation technique. The fractured files and the operating time were recorded. The shaping abilities of two types of NiTi files were analyzed. Results No Reciproc was separated, whereas two pieces of Mtwo were separated. The preparation time of Group R averaged (15.45±3.16) minutes, and Group M averaged (20.31±2.32) minutes, and the difference was statistically significant(P<0.05)．No transportatio，apical blockage,ledge or perforation was found in the two groups. Conclusion Two types of NiTi instruments also show high performance when they are used to molar root canal preparation,but Mtwo instruments need more time and we should pay attention to prevent the fracture of it．

Key words: Reciproc, Mtwo, NiTi file, root canal preparation
