摘要/Abstract

摘要： 目的: 比较新一代往复运动单支锉WaveOne Gold和Reciproc Blue与上一代WaveOne和Reciproc在根管预备后产生牙本质微裂的差异。方法: 将90颗离体下颌单根前磨牙随机分为6组（n=15）,分别为手用K锉组、WaveOne组、Reciproc组、WaveOne Gold组、Reciproc Blue组和空白对照组。将实验组根管预备至25#,空白对照组不作预备。利用硬组织切片机在距根尖孔3、6和9 mm处水平切割牙根,体视显微镜下放大25倍,观察不同横截面牙本质微裂情况。采用SPSS 17.0软件包对数据进行统计学分析。结果: 手用K锉组和空白对照组未发现牙本质微裂;实验组中,WaveOne、WaveOne Gold、Reciproc和Reciproc Blue在根管预备后均产生了牙本质微裂,其中,WaveOne和手用K锉组产生的牙本质微裂纹数目差异有统计学意义（P<0.05）,裂纹主要集中于根管根中段;Reciproc和Reciproc Blue 2种往复运动单支锉造成的牙本质微裂数目相同,与对照组相比无统计学差异。结论: 使用新一代往复运动单支锉WaveOne Gold和Reciproc Blue不会增加根管预备后牙本质微裂纹发生的风险。

Abstract: PURPOSE: To compare the incidence of dentinal microcracks after root canal preparation by new generation of nickel-titanium instrument WaveOne Gold, Reciproc Blue with previous WaveOne and Reciproc. METHODS: Ninety extracted single-rooted mandibular premolars were randomly divided into 6 groups(n=15). The root canals were instrumented by using Hand K files, WaveOne, Reciproc, WaveOne Gold and Reciproc Blue. Fifteen teeth were left unprepared and served as negative controls. The root canals were all prepared to 25#. The roots were then sectioned at 3 mm, 6 mm and 9 mm from the apical orifice using a hard tissue slicer. The slices were observed under stereoscopic microscope at ×25 magnification. SPSS 17.0 software package was used for statistical analysis. RESULTS: No dentinal microcrack was found in the hand K files group and negative control group. The reciprocating single files WaveOne, WaveOne Gold, Reciproc and Reciproc Blue all produced dentinal microcracks after root canal preparation. The WaveOne generated the most dentinal microcracks than the hand K files(P<0.05), and the microcracks were mainly concentrated in the middle part of the root. The number of dentinal microcracks caused by Reciproc and Reciproc Blue was the same, with no significant difference(P>0.05). CONCLUSIONS: The new generation of reciprocating files of WaveOne Gold and Reciproc Blue may not increase the incidence of dentinal microcracks after root canal preparation.
