The purpose of this study was to compare AH Plus Bioceramic Sealer (AHPB), AH Plus (AHP), MTA Fillapex (MTAF), and Sure-Seal (SS) sealers for dentinal tubular penetration ability.
Forty extracted human mandibular premolars were instrumented and divided into 4 groups based on the sealer used for filling (n = 10): AHPB, AHP, MTAF, SS. After filling the root canals, the roots were entombed in acrylic resin blocks and cut vertically in the long axis to obtain 1-mm-thick disks from 3 mm (at apical third), 8 mm (at middle third) and 13 mm (at coronal third) away the apical foramen. The images of 120 samples (30 for each group) were scanned by using confocal laser scanning microscopy and analyzed with the ImageJ software. Total penetration area and the root canal area were measured, and the ratio of these values were recorded as sealer penetration ratio. The data were evaluated for each third and in total using one-way ANOVA with post-hoc Tukey's test. The significance level was set to P < 0.05.
In the apical, middle and coronal thirds and in total, MTAF and AHP, and SS and AHPB had statistically significant identical penetration ratio values. Both SS and AHPB demonstrated statistically considerably greater penetration % as compared to MTAF and AHP in all thirds (P < 0.05), and in total (P < 0.05).
AHPB and SS provided a higher penetration % than AHP and MTAF in apical, middle and coronal thirds, and in total.
本研究的目的是比较AH Plus生物陶瓷封闭剂（AHPB）、AH Plus封闭剂（AHP）、MTA Fillapex封闭剂（MTAF）和Sure-Seal封闭剂（SS）的牙本质小管渗透能力。
选取40颗拔除的人下颌前磨牙进行根管预备，并根据用于充填的封闭剂分为4组（n = 10）：AHPB组、AHP组、MTAF组、SS组。根管充填后，将牙根包埋在丙烯酸树脂块中，沿长轴垂直切割，从距根尖孔3 mm（根尖三分之一处）、8 mm（根中三分之一处）和13 mm（根冠三分之一处）获取1 mm厚的切片。使用共聚焦激光扫描显微镜对120个样本（每组30个）的图像进行扫描，并使用ImageJ软件进行分析。测量总渗透面积和根管面积，将这些值的比值记录为封闭剂渗透比。使用单因素方差分析和事后Tukey检验对每个三分之一部分和总体数据进行评估。显著性水平设定为P < 0.05。
在根尖、根中、根冠三分之一部分及总体上，MTAF与AHP、SS与AHPB的渗透比值具有统计学意义上的相同性。在所有三分之一部分及总体上，SS和AHPB的渗透百分比均显著高于MTAF和AHP（P < 0.05）。
在根尖、根中、根冠三分之一部分及总体上，AHPB和SS的渗透百分比高于AHP和MTAF。
