摘要

摘要:次氯酸钠(NaOCl)被动微容量灌洗(PMI)是一种新的根管消毒方法。它是基于这样的概念,即根管器械不规则的表面特性可以在不施加任何压力的情况下,将NaOCl携带到管腔中,并控制液体量。目的:比较和评价3%和5% NaOCl PMI、生理盐水PMI和3% NaOCl标准冲洗(SI)去除单根牙颈、中、尖三分之一根管壁涂片层(SL)的效果。材料和方法:本研究在印度安得拉邦Vishnu牙科学院保守牙科和牙髓学部门进行。该研究于2018年2月进行。收集40个上颌中切牙,在研究后3个月内拔出。根据冲洗方法将牙齿分为4组(n=10):组1 (3.0% NaOCl SI)、组2 (3.0% NaOCl PMI)、组3 (5.0% NaOCl PMI)、组4(生理盐水PMI)。所有样品都用Protaper旋转锉测量到F4尺寸,最后用17%乙二胺四乙酸(EDTA)冲洗。扫描电镜(SEM)观察SL去除情况。使用SPSS 21.0软件对数据进行分析。统计检验采用Kruskal Wallis检验和Mann-Whitney-U检验。p值为<0.05被认为在所有比较中具有统计学意义。结果:3.0% NaOCl SI、3.0% NaOCl PMI和5.0% NaOCl PMI在根管中部和根尖三分之一处的SL拔除效果无显著差异(p>0.05)。然而,与其他组相比,5.0% NaOCl PMI在颈椎第三段的SL清除效率显著提高(p<0.05)。结论:3%和5% NaOCl与3%次氯酸盐SI在根管中部和根尖三分之一处的被动微容量灌洗效果相当。

Evaluation of Intracanal Smear Layer Removal after Passive Microvolume Irrigation with Sodium Hypochlorite and Rotary NickelTitanium Instruments: An In-vitro Study
Introduction: Passive Microvolume Irrigation (PMI) with Sodium Hypochlorite (NaOCl) has been proposed as a new method for root canal disinfection. It is based on the concept that irregular surface characteristics of endodontic instruments can carry NaOCl into the canal space with controlled fluid volume, without applying any pressure. Aim: To compare and evaluate the efficacy of 3% and 5% NaOCl PMI, Saline PMI, and 3% NaOCl Standard Irrigation (SI) in removing the Smear Layer (SL) from the root canal walls at the cervical, middle, and apical thirds of single-rooted teeth. Materials and Methods: This study was conducted in the Department of Conservative Dentistry and Endodontics at Vishnu Dental College, Andhra Pradesh, India. The study was conducted in February 2018. Forty maxillary central incisors with a single canal, extracted within three months of the study, were collected. The teeth were divided into four groups (n=10) based on the irrigation method: Group-1 (3.0% NaOCl SI), Group-2 (3.0% NaOCl PMI), Group-3 (5.0% NaOCl PMI), and Group-4 (Saline PMI). All samples were instrumented upto F4 size with Protaper rotary files, and a final rinse of 17% Ethylenediaminetetraacetic Acid (EDTA) was used. SL removal was evaluated using Scanning Electron Microscope (SEM). The data were analysed using Statistical Package for Social Sciences (SPSS) 21.0. Statistical tests used were Kruskal Wallis and Mann-Whitney-U tests. A p-value of <0.05 was considered statistically significant for all comparisons. Results: There was no significant difference (p>0.05) in SL removal between 3.0% NaOCl SI, 3.0% NaOCl PMI, and 5.0% NaOCl PMI in the middle and apical thirds of the root canals. However, 5.0% NaOCl PMI showed significantly higher efficiency in SL removal at the cervical third compared to the other groups (p<0.05). Conclusion: Passive microvolume irrigation with 3% and 5% NaOCl showed comparable efficacy to 3% hypochlorite SI in the middle and apical thirds of the root canal.
