摘要

目的研究在存在和不存在表面活性剂“苯扎氯铵”的情况下,根管冲洗对Wave One Gold Primary (WOG)、Reciproc Blue R25 (RB)和Protaper Next X2 (PTN)根管旋转器械在模拟根管预备过程中最大操作扭矩和垂直力的影响。材料与方法采用自制的自动灌洗及扭矩/力分析装置,与内源性马达连接。采用模拟根管弯曲度为35°的丙烯酸树脂块,每个锉随机分为6组。在模拟根管预备过程中,使用连续旋转或往复运动的灌洗剂:5% NaOCl和5% NaOCl加0.84%苯扎氯铵。在制备过程中记录了锉的最大扭矩和垂直力值。结果BAC加入NaOCl对仪器最大扭矩值无显著影响(p < 0.05)。与PTN和RCB相比,两组WOG产生的扭矩值最低(p<0。05)。NaOCl+BAC组RB产生的垂直力高于WOG和PTN组。表面改性剂降低WOG器械的最大受力值(p<0.05)。讨论NaOCl中加入表面活性剂对仪器的最大扭矩和力没有负面影响。

Effect of Sodium Hypochlorite Irrigation with and Without Surfactant on Maximum Operative Torque and Vertical Force of Nickel-Titanium Endodontic Instruments
Objectives This study aimed to evaluate the effects of root canal irrigation on maximum operative torque and vertical force of Wave One Gold Primary (WOG), Reciproc Blue R25 (RB) and Protaper Next X2 (PTN) endodontic rotary instruments during simulated root canal preparation in the presence and absence of a surfactant “benzalkonium chloride”. Material and Methods A custom-made automated irrigation and torque/force analyzing device connected with endomotor was used for the study. Acrylic resin blocks with simulated curved root canals of 35° were randomly assigned to 6 groups for each file. The following irrigants were used during simulated root canal preparation with continuous rotation or reciprocation motion with pecking mode: 5% NaOCl and 5% NaOCl with 0.84% benzalkonium chloride. Maximum torque and vertical force values of files were recorded during preparation. Results BAC addition to NaOCl did not significantly affect maximum torque values of instruments (p>0.05). WOG generated lowest torque value compared with PTN and RCB in both groups (p<0. 05). RB generated higher vertical force compared with WOG and PTN instruments in NaOCl+BAC group. The surface modifier decreased the maximum force value of WOG instrument (p<0.05). Discussion Surfactan addition to NaOCl had no negative effects on maximum torque and force of the instruments.
