Abstract

This study evaluated the impact of canal irrigation using surfactants associated to NaOCl on the percentage of voids of root canal filling through micro-computed tomographic (micro-CT) analysis. 27 mandibular mesial roots with Vertucci type II canal configuration with isthmus were selected and scanned in a micro-CT device. The specimens were assigned to three groups (n = 9), according to the irrigation solution during instrumentation: 2.5% NaOCl without additives (control), 2.5% NaOCl with 0.1% Benzalkonium Chloride and 2.5% NaOCl with 0.1% Tween 80. After obturation, the specimens were rescanned, and the percentage of voids were calculated. Data were analysed using one-way ANOVA with a significance level of 5%. The percentage of voids were similar among the groups (p > 0.05). None of the specimens showed completely voids-free areas. The addition of surfactants to NaOCl irrigation did not improve the quality of root canal filling of mandibular mesial root canals.

在 NaOCl 灌溉中添加表面活性剂是否会影响根管充填的空隙百分比？

本研究通过微型计算机断层扫描（micro-CT）分析，评估了使用与 NaOCl 相关的表面活性剂灌洗根管对根管填充空隙百分比的影响。研究选取了 27 个具有峡部 Vertucci II 型根管结构的下颌中牙根，并用微型计算机断层扫描装置进行了扫描。根据器械操作时的冲洗溶液，将标本分为三组（n = 9）：不含添加剂的 2.5% NaOCl（对照组）、含 0.1% 苯扎氯铵的 2.5% NaOCl 和含 0.1% 吐温 80 的 2.5% NaOCl。封固后，重新扫描试样并计算空隙百分比。数据采用单因素方差分析，显著性水平为 5%。各组的空隙百分比相似（P > 0.05）。没有一个试样显示出完全无空隙区域。在 NaOCl 冲洗中添加表面活性剂并不能改善下颌中根管的根管充填质量。

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.
