Abstract

Objectives: Activation of sodium hypochlorite (NaOCl) to remove biofilm from lateral canal is important for the success of endodontic treatment. This study aimed to compare the biofilm dissolving capacity of different irrigation techniques in resin blocks with two lateral canals manufactured with 3D printers.  Materials and methods: Biofilm-mimicking hydrogel was placed in the upper and lower lateral canals of 75 resin blocks. Main canals of the blocks were irrigated with 5% NaOCl. Then, the blocks were randomly divided into five groups: sonic activation (SA), passive ultrasonic irrigation (PUI), intracanal heating (ICH), self-adjusting file (SAF) and control. The amount of hydrogel removed was measured by weighing the blocks before and after the treatment and further visually scored. Data were analyzed using Kruskall Wallis H, Wilcoxon, Tukey Post-hoc HSD (Honestly Significant Difference) and one-way ANOVA tests.

Results: The SAF group showed the highest hydrogel scores compared to other groups (p < 0.05). The hydrogel dissolution capacity of the SA group was lower compared to SAF, PUI and ICH techniques (p < 0.05). Based on visual scoring, SAF group was superior to other activation methods (p < 0.05) which are similar to each other (p > 0.05) in both upper and lower lateral canals.  Conclusion: All activation methods were superior than the control group. The SAF system demonstrated superior hydrogel dissolving ability, while SA, PUI, and ICH groups showed similar effectiveness.

不同ırrigation激活方法对侧管生物膜去除效果的比较- ın体外研究。
目的:激活次氯酸钠(NaOCl)去除根管外根管生物膜是根管治疗成功的重要因素。本研究旨在比较用3D打印机制造的具有两个侧管的树脂块中不同灌溉技术的生物膜溶解能力。材料和方法:将模拟生物膜的水凝胶放置在75个树脂块的上、下外侧管中。块体主渠用5% NaOCl灌水。然后,将block随机分为5组:超声激活(SA)组、被动超声灌洗(PUI)组、管内加热(ICH)组、自调节锉(SAF)组和对照组。通过对治疗前后的块进行称重来测量去除的水凝胶量,并进一步进行视觉评分。数据分析采用Kruskall Wallis H、Wilcoxon、Tukey事后HSD(诚实显著差异)和单因素方差分析检验。结果:与其他各组相比,SAF组水凝胶评分最高(p < 0.05)。与SAF、PUI和ICH技术相比,SA组的水凝胶溶解能力较低(p < 0.05)。根据视觉评分,SAF组在上、下外侧管上均优于其他相似的激活方法(p < 0.05)。结论:各激活方法均优于对照组。SAF系统表现出优异的水凝胶溶解能力,而SA、PUI和ICH组表现出相似的效果。
