Abstract：
UNASSIGNED: Smear layer clearance and sealer penetration into dentinal tubules play a crucial role in root canal treatment. Hence, efficient irrigation is a crucial component of the root canal debridement. This in vitro study\'s objective was to assess the effectiveness of passive ultrasonic activation and Erbium: yttrium-aluminum-garnet (Er: YAG) laser-activated irrigation on irrigation solution penetration and sealer penetration into dentinal tubules.
UNASSIGNED: The aim of this study was to evaluate and compare the dentinal tubule penetration of epoxy resin-based sealer and bioceramic sealer after ultrasonic agitation and Er: YAG laser activation of the irrigant.
UNASSIGNED: This was an in vitro study.
UNASSIGNED: Extracted tooth samples (n = 42) into 06 groups (Group A-F) with 7 samples in each group. Postobturation transverse section was made and assessed under a confocal laser scanning microscope for the total dentinal tubule penetration area and recorded as the mean apical, middle, and coronal penetration.
UNASSIGNED: One-way analysis of variance test, followed by post hoc was used.
UNASSIGNED: The intergroup comparison showed that Group E and Group F have significantly more penetration as compared to the controls and ultrasonic irrigation, P < 0.001 and P < 0.01, respectively.
UNASSIGNED: Er: YAG laser with AH plus sealer has the highest penetration in all the sections of tooth, followed by CeraSeal sealer.

摘要：
■涂抹层清除和密封剂渗入牙本质小管在根管治疗中起着至关重要的作用。因此，有效的冲洗是根管清创的重要组成部分。这项体外研究的目的是评估被动超声激活和铒：钇铝石榴石（Er：YAG）激光激活冲洗对冲洗溶液渗透和密封剂渗透进入牙本质小管的有效性。
■这项研究的目的是评估和比较基于环氧树脂的密封剂和生物陶瓷密封剂在超声搅拌和Er：YAG激光激活冲洗剂后的牙本质小管渗透。
■这是一项体外研究。
■将牙齿样本（n=42）提取到06组（A-F组）中，每组7个样本。制作闭塞后横切面，并在共聚焦激光扫描显微镜下评估总牙本质小管穿透面积，并记录为平均根尖，中间,和日冕穿透。
■方差检验的单向分析，其次是事后使用。
■组间比较显示，与对照组和超声灌洗相比，E组和F组的穿透率明显更高，P<0.001和P<0.01。
■带有AH加密封剂的Er：YAG激光器在牙齿的所有部分中具有最高的穿透性，其次是CeraSeal密封剂。
