Abstract

OBJECTIVE

The purpose of this study was to compare the depth of dentinal tubule sealer penetration in the apical thirds of severely curved root canals obturated with Resilon/Epiphany self-etch (SE) or gutta-percha/AH Plus using scanning electron microscopy.

MATERIALS AND METHODS

A total of 34 extracted human mandibular molars with 25-40° curvature of the mesial root canal were selected for this study. After preparation, the mesiobuccal canals were randomly obturated with gutta-percha and AH Plus sealer or Resilon and Epiphany SE sealer. Sealer penetration was evaluated in 2 mm sections of the apical thirds of roots using scanning electron microscopy. Data were analyzed using the independent t-test and Mann-Whitney U-test, with significance set at P < 0.05.

RESULTS

Mean tubular penetration depth did not differ significantly between Resilon SE (172.22 μm) and AH Plus (122.18 μm; P > 0.05). The density of sealer tags in the apical thirds of root canals was also equivalent (P > 0.05).

CONCLUSION

Average penetration into dentinal tubules in the apical thirds of severely curved roots did not differ significantly between Epiphany SE and AH Plus.

摘要

目的

本研究旨在使用扫描电子显微镜比较用Resilon/Epiphany自酸蚀（SE）或牙胶/AH Plus封闭的严重弯曲根管根尖三分之一处牙本质小管封闭剂的渗透深度。

材料与方法

本研究共选取34颗拔除的人类下颌磨牙，其近中根管弯曲度为25 - 40°。预备后，近中颊根管随机用牙胶和AH Plus封闭剂或Resilon和Epiphany SE封闭剂进行封闭。使用扫描电子显微镜在根尖三分之一处的2mm根段评估封闭剂的渗透情况。数据采用独立t检验和曼-惠特尼U检验进行分析，显著性设定为P < 0.05。
