Abstract

This research examines canal transportation and centering ability of single-file systems when operated in continuous rotation or reciprocation. Sixty J-shaped resin blocks were used. The specimens were divided into two main groups (n = 30). Then, based on the motion used to operate the instruments, each group was subdivided into two subgroups (n = 15). Group A1: One Curve/rotation, Group A2: One Curve/clockwise reciprocation, Group B1: WaveOne Gold/Reciprocation, Group B2: WaveOne Gold/counter-clockwise rotation. Pre- and post-instrumentation images were obtained using digital microscope. Canal transportation was measured at five levels. A non-significant difference (p > 0.05) resulted between two motions at all levels. However, group A1 showed significantly less transportation at levels 3 and 4 (p ≤ 0.05), also more centered preparation at level 4 (p ≤ 0.05) than group B1. Within the limitations of this study, the apical transportation and centering ability of single-file systems are unaffected by different kinematics.

两种运动学对WaveOne Gold和One Curve文件的运河运输和定心能力的影响。

本研究考察了单文件系统在连续旋转或往复运动中运行时的运河运输和居中能力。使用了60个J形树脂块。标本分为两个主要组（n = 30）。然后，根据操作仪器的动作，每组被细分为两个亚组（n = 15）。A1组：一条曲线/旋转，A2组：一个曲线/顺时针往复，B1组：WaveOne Gold/往复，B2组：Wave One Gold/逆时针旋转。使用数字显微镜获得仪器前后的图像。运河运输在五个层面进行了测量。无显著性差异（p > 0.05）在所有水平的两个运动之间产生。然而，A1组在第3级和第4级的运输量显著减少（p ≤ 0.05），在第4级的准备也更集中（p ≤ 0.05）显著高于B1组。在本研究的限制范围内，单个文件系统的顶端传输和居中能力不受不同运动学的影响。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
