Abstract

Objective: Biomechanical root canal preparation involves both mechanical instrumentation and endodontic irrigation, aiming to reduce bacterial levels to promote periradicular healing. However, complete removal of biofilm and debris, especially in complex canal morphologies, remains difficult. This study aimed to evaluate, through microcomputed tomography (micro-CT), the use of the XP-Endo Finisher and Tornado Disinfection Kit (TDK) systems during the final agitation of the irrigating solution for the final debridement of oval-shaped canals of lower incisors.

Methods: Thirty-nine extracted human mandibular incisors were instrumented up to size #25/.05 and divided into three groups (n=13) based on the final irrigation system: Conventional irrigation with syringe and needle (CI), XP-Endo Finisher (XPF), and TDK. 40 mL of 2.5% NaOCl was used for each group. Teeth were scanned ex vivo using a micro-CT before instrumentation, after instrumentation, and after irrigation. Three-dimensional root canal models were evaluated for volume, untouched surfaces, and dentin removal. Data were analyzed using repeated-measures ANOVA, t-test, and Tukey tests (p<0.05).

Results: TDK showed a significant difference in total and cervical third compared to CI and XPF regarding volume and dentin removal analysis (p<0.05), with no significant difference in the apical third compared to XPF (p>0.05). TDK had a lower percentage of untouched volume compared to the other systems in the overall analysis (p<0.05) and at all thirds compared to CI (p<0.05).

Conclusion: Supplementary instruments improve root canal debridement compared to conventional irrigation, particularly in smaller apical diameters and oval-shaped canals of lower incisors. TDK offers enhanced wall contact after root canal preparation and is a viable alternative for complementing debridement. (EEJ-2024-10-158).

磨料扩张系统对椭圆管清创能力的微ct分析:实验室研究。
目的:生物力学根管准备包括机械器械和根管灌洗,旨在减少细菌水平,促进根周愈合。然而,完全去除生物膜和碎屑,特别是在复杂的管道形态中,仍然很困难。本研究旨在通过微型计算机断层扫描(micro-CT)评估XP-Endo Finisher和Tornado消毒套件(TDK)系统在冲洗液最后搅拌期间用于下门牙椭圆形管的最终清创。方法:将39颗拔除的人下颌骨切牙固定至25号。根据最终灌洗方式分为常规针筒灌洗(CI)、XP-Endo Finisher (XPF)和TDK三组(n=13)。每组取2.5% NaOCl 40 mL。在器械前、器械后和冲洗后使用micro-CT对牙齿进行离体扫描。评估三维根管模型的体积、未触及表面和牙本质去除。使用重复测量方差分析、t检验和Tukey检验对数据进行分析(结果:TDK在体积和牙本质去除分析方面显示,与CI和XPF相比,TDK在总和宫颈三分之一方面存在显著差异(p0.05)。与其他系统相比,TDK的未触及体积百分比较低(结论:与传统灌洗相比,辅助器械改善了根管清创,特别是在较小的根尖直径和椭圆形的下门牙根管中。TDK在根管准备后提供增强的管壁接触,是补充清创的可行选择。(eej - 2024 - 10 - 158)。
