Abstract

AIM: This study aimed to calculate the percentage of touched surfaces and changes in the cross-sectional area of oval-shaped root canals after preparation using (XP-endo Shaper, IRace, and HyFlex CM) rotary systems using AutoCAD software. MATERIALS AND METHODS: Sixty extracted single-rooted mandibular premolars were collected and divided into three main groups according to the rotary system used (n = 20). Each tooth was impeded in a resin block, coded, sectioned, and photographed under a stereomicroscope, before and after instrumentation. Microphotographs were analyzed using AutoCAD software. Two-way ANOVA was used to evaluate the mean percentage of the touched surface and mean cross- sectional area between the groups and tooth segments, followed by Tukey’s post hoc test for pair-wise comparisons. RESULTS: The percentage of touched canal walls was significantly different between IRace group and each of XP-endo Shaper and HyFlex CM groups (p < 0.001). A statistically significant difference was recorded for the mean change in the cross-sectional areas of the root canal between IRace group and both HyFlex CM and XP-endo Shaper groups, respectively (p < 0.001). For all groups, there was a significant difference in the change in the cross- sectional area between all segments (coronal, middle, and apical). CONCLUSIONS: Within the limitations of this study, the XP-endo Shaper and HyFlex CM files had a higher cutting efficiency and maintained better root stability than the IRaCe system by preserving the dentin of the oval root canal. This was observed at all the canal levels in the coronal, middle, and apical segments.

使用AutoCAD软件评估XP-endo Shaper、IRaCe和HyFlex CM器械后椭圆形根管接触表面百分比和截面积变化

目的:本研究旨在利用AutoCAD软件计算使用(XP-endo Shaper、IRace和HyFlex CM)旋转系统预备后的椭圆形根管接触面百分比和截面积变化。材料与方法:收集60颗拔除的单根下颌前磨牙，根据所使用的旋转系统分为三组(n = 20)。每颗牙齿在树脂块中被阻挡，编码，切片，并在体视显微镜下拍照，在仪器之前和之后。用AutoCAD软件对显微照片进行分析。采用双因素方差分析(Two-way ANOVA)评估各组和牙节之间的平均接触表面百分比和平均横截面积，然后采用Tukey事后检验进行两两比较。结果:IRace组与XP-endo Shaper组和HyFlex CM组的管壁接触率差异有统计学意义(p <0.001)。IRace组与HyFlex CM组和XP-endo Shaper组根管截面积的平均变化差异有统计学意义(p <0.001)。在所有组中，所有节段(冠状、中间和根尖)的横截面积变化均有显著差异。结论:在本研究的限制范围内，XP-endo Shaper和HyFlex CM锉比IRaCe系统具有更高的切削效率，并通过保留椭圆形根管的牙本质来保持更好的根稳定性。在冠状段、中段和根尖段的所有根管水平均观察到这种情况。

期刊介绍： Open Access Macedonian Journal of Medical Sciences (OAMJMS) [formerly known as Macedonian Journal of Medical Sciences] is a top-tier open access medical science journal published by the ID Design 2012/DOOEL Skopje, Rajko Zhinzifov No 48, 1000 Skopje, Republic of Macedonia. OAMJMS is an international, modern, general medical journal covering all areas in the medical sciences, from basic studies to large clinical trials and cost-effectiveness analyses. We publish mostly human studies that substantially enhance our understanding of disease epidemiology, etiology, and physiology; the development of prognostic and diagnostic technologies; trials that test the efficacy of specific interventions and those that compare different treatments; and systematic reviews. We aim to promote translation of basic research into clinical investigation, and of clinical evidence into practice. We publish occasional studies in animal models when they report outstanding research findings that are highly clinically relevant. Our audience is the international medical community as well as educators, policy makers, patient advocacy groups, and interested members of the public around the world. OAMJMS is published quarterly online version. The Open Access Macedonian Journal of Medical Sciences (OAMJMS) publishes Medical Informatics, Basic Science, Clinical Science, Case Report, Brief Communication, Public Health, Public Policy, and Review Article from all fields of medicine and related fields. This journal also publishes, continuously or occasionally, the bibliographies of the members of the Society, medical history, medical publications, thesis abstracts, book reviews, reports on meetings, information on future meetings, important events and dates, and various headings which contribute to the development of the corresponding scientific field.
