The aim of this study was to compare and evaluate the dentinal tubule penetration and adaptation of a premixed bioceramic sealer and an epoxy-resin based sealer in the three radicular thirds.
30 wide roots, with single straight canals and totally formed apexes, were endodontically prepared and divided into two groups (n=14) according to the sealer used for root canal filling: AH-Plus (AHP) and Bio-C Sealer (BIOC). Two samples were left as controls. After the canals were filled, the samples were cut and viewed under Scanning Electron Microscopy by taking images to analyse the tubular penetration and adaptation of the sealers. The results were statistically analysed with the Shapiro Wilk, Levene and Mann-Whitney tests (P<0.05).
BIOC showed significantly higher penetration in dentinal tubules than AHP in the cervical, middle and apical thirds of the root canal (P<0.05) and better adaptation to the dentinal tubule walls.
Under the parameters of this study, BIOC exhibits higher penetration and better adaptation to the dentinal tubules compared to AHP.
本研究旨在比较和评估预混生物陶瓷封闭剂和环氧树脂基封闭剂在根管三个根尖段的牙本质小管渗透及适应性。
选取30颗具有单一直根管且根尖完全形成的宽大牙根，进行根管预备，并根据用于根管充填的封闭剂分为两组（n = 14）：AH-Plus（AHP）组和Bio-C封闭剂（BIOC）组。留两个样本作为对照。根管充填后，将样本切开，在扫描电子显微镜下观察并拍照，以分析封闭剂的小管渗透及适应性。结果采用Shapiro Wilk、Levene和Mann-Whitney检验进行统计学分析（P<0.05）。
在根管的颈段、中段和根尖段，BIOC在牙本质小管中的渗透显著高于AHP（P<0.05），并且对牙本质小管壁的适应性更好。
在本研究参数下，与AHP相比，BIOC对牙本质小管具有更高的渗透性和更好的适应性。
