Abstract

This study aimed to evaluate the influence of a new multifunctional single endodontic irrigant on the push-out bond strength and adhesive interface between gutta-percha and an epoxy resin-based sealer and root dentine. Forty-eight human maxillary canines were randomly assigned to four irrigation protocols (n = 12): NaOCl 2.5% + EDTA 17% + saline (SHE), Triton solution + saline (T), Triton solution + EDTA 17% + saline (TE) and NaOCl 2.5% + Triton solution + saline (SHT). Root canals were prepared with the WaveOne Gold Large system and obturated using a single WaveOne Large cone with AH Plus sealer. The SHE group showed the highest bond strength (4.87 ± 0.84 MPa), significantly higher than those of the other groups (p < 0.001). Scanning Electron Microscopy (SEM) revealed better adaptation in SHE, whereas T, TE and SHT exhibited gaps. The new irrigant resulted in lower bond strength and poorer adaptation of the adhesive interface.

一种新型的单一多功能根管冲洗液增强树脂基密封剂与根牙本质的结合强度和粘附界面。

本研究旨在评估一种新型多功能单一根管冲洗剂对杜仲胶与环氧树脂基密封剂和根本质之间的推出结合强度和粘附界面的影响。48只上颌犬随机分为4组（n = 12）： NaOCl 2.5% + EDTA 17% +生理盐水（SHE）、Triton溶液+生理盐水(T)、Triton溶液+ EDTA 17% +生理盐水（TE）和NaOCl 2.5% + Triton溶液+生理盐水（SHT）。使用WaveOne Gold Large系统准备根管，并使用带有AH Plus密封剂的单个WaveOne Large锥体进行封闭。SHE组黏结强度最高（4.87±0.84 MPa），显著高于其他各组(p

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.
