Abstract

The aim of this study was to compare three delivery methods of a hydraulic calcium silicate cement-based sealer by quantifying voids using the single-cone technique. Forty-eight human mandibular molars were instrumented and scanned using micro-computed tomography. The specimen's aspect ratio, shape, and volume were analysed to allow even distribution across three experimental groups (n = 16): sealer injection with a syringe, coating of the master cone and sealer injection followed by sonic agitation. Post-filling micro-computed scanning was used to quantify void volumes in each specimen. Statistical analysis using Kruskal-Wallis and Dunn's post hoc tests (α = 0.05) revealed no significant difference in void volume among the delivery methods (p = 0.120). However, canal shape was a significant factor; round canals exhibited significantly fewer voids than any other shape (p < 0.001). In conclusion, the delivery method did not influence the density of the root canal filling; canal anatomy was the more critical determinant factor for void formation.

水力硅酸钙水泥基封口剂输送方式对孔隙形成的影响：微计算机断层扫描研究。

本研究的目的是通过使用单锥技术定量孔隙来比较液压硅酸钙水泥基密封剂的三种输送方法。对48颗人类下颌磨牙进行了显微计算机断层扫描。对标本的纵横比、形状和体积进行了分析，以使其均匀分布在三个实验组（n = 16）：用注射器注射密封剂、涂覆主锥和注射密封剂，然后进行声波搅拌。填充后的微计算机扫描用于量化每个标本的空隙体积。采用Kruskal-Wallis和Dunn事后检验（α = 0.05）进行统计学分析，不同给药方式的空腔容量差异无统计学意义（p = 0.120）。然而，运河形状是重要的因素；圆形管道比任何其他形状的管道显示出更少的空隙

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.
