Abstract

This study evaluated the reliability of sealer penetration measurement methods used with confocal laser scanning microscopy in correlation with the percentage of residual root filling and examined the effect of residual root-filling material on dentine penetrability after retreatment. Extracted teeth were randomly divided into different groups according to the obturation sealer used (n = 6); BioRoot RCS; MTA Fillapex; Bio-C and AH Plus. Root-filling material was removed before the secondary chemo-mechanical preparation and obturation using fluorescein labelled AH Plus. Multiple micro-computed tomography scans were obtained followed by confocal laser scanning microscopy to measure the penetration of the labelled sealer into the dentinal tubules using four different methods. Measuring sealer penetration into radicular dentine using the penetration percentage method was found to be the most reliable. Dentine penetrability during retreatment did not seem to be affected by the type of residual root-filling material.

牙髓再治疗后封闭剂渗透性测量方法和牙本质渗透性评估的可靠性:相关体外研究
本研究评估了共聚焦激光扫描显微镜使用的封闭剂渗透性测量方法与残留根充百分比相关性的可靠性,并研究了残留根充材料对再治疗后牙本质渗透性的影响。拔牙后,根据所使用的钝化封闭剂(n = 6)、BioRoot RCS、MTA Fillapex、Bio-C 和 AH Plus,随机分为不同的组别。在使用荧光素标记的 AH Plus 进行二次化学机械预备和封闭之前,先去除根部填充材料。使用四种不同的方法测量标记的封闭剂渗入牙本质小管的情况,然后使用共聚焦激光扫描显微镜进行多次显微计算机断层扫描。结果发现,使用渗透百分比法测量封闭剂渗入根尖牙本质的情况最为可靠。再治疗过程中牙本质的渗透性似乎不受残留根充材料类型的影响。

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.
