Abstract

Objective: To investigate the efficacy of different obturation techniques on sealer penetration in teeth with internal root resorption using confocal laser microscopy.

Methods: An artificial internal resorption cavity (3 mm deep and 1.2 mm in diameter) was formed in the round-shaped root canals of 45 single-rooted teeth at a distance of 7 mm from the apex, then roots were instrumented (size 40/.06). The samples were divided into three groups (n = 15) according to the obturation technique: lateral compaction (LC), warm vertical compaction (WVC) and carrier-based (CB).

Results: In the resorption regions, the sealer penetration depth in the CB and LC groups was significantly higher than that in the WVC group (P < 0.05).

Conclusion: Within the limitations of this study, the penetration depth of the sealer in the resorption region was higher in the CB and LC groups as compared to that in the WVC group.

不同封闭技术对人工内根吸收牙体中封闭剂渗透的影响:共聚焦激光显微镜分析。

目的:用激光共聚焦显微镜观察不同封闭方法对牙体内根吸收的影响。方法:选取45颗单根牙，在距根尖7 mm的圆形根管内形成人工内吸收腔(深3 mm，直径1.2 mm)，并固定根管(尺寸40/ 0.06)。根据封闭技术将样品分为3组(n = 15):侧向压实(LC)、温垂直压实(WVC)和载体压实(CB)。结果:在吸收区，CB组和LC组的密封剂穿透深度显著高于WVC组(P < 0.05)。结论:在本研究的限制范围内，CB组和LC组封闭剂在吸收区的渗透深度高于WVC组。
