Abstract

The aim of this study was to assess by confocal laser microscope the depth of dentinal tubule penetration of two tricalcium silicate-based sealers promoted by two obturation techniques in curved canals compared with AHPlus. One hundred and twenty canals were divided into six groups (n = 20): BCSC-Bio-C Sealer (BC) and single-cone technique (SC); BCCW-BC and continuous condensation wave (CW); TFSC-Total Fill (TF) and SC; TFCW-TF and CW; AHSC-AH Plus (AH) and SC; AHCW-AH and CW. Data were analysed using the three-way ANOVA and Tukey's test (α = 5%). Penetration depth was significantly greater for TFCW than TFSC and greater for AHCW than AHSC (p < 0.05). There was no significant difference between BCCW and BCSC (p > 0.05). The penetration of TF was significantly greater (p < 0.05). The CW technique promoted greater intratubular penetration, except for the BC sealer.

封闭技术对两种硅酸三钙封闭剂牙本质小管渗透的影响：体外研究。

本研究的目的是通过激光共聚焦显微镜评估两种硅酸三钙基封闭剂的牙本质小管穿透深度，与 AHPlus 相比，两种封闭技术在弯曲根管中促进了硅酸三钙基封闭剂的穿透。120 根根管被分为六组（n = 20）：BCSC-Bio-C封闭剂（BC）和单锥技术（SC）；BCCW-BC和连续冷凝波（CW）；TFSC-全填充（TF）和SC；TFCW-TF和CW；AHSC-AH Plus（AH）和SC；AHCW-AH和CW。数据分析采用三方方差分析和 Tukey 检验（α = 5%）。渗透深度 TFCW 明显大于 TFSC，AHCW 大于 AHSC（p 0.05）。TF 的穿透深度明显大于 AHSC（p 0.05）。

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.
