OBJECTIVE
To evaluate the apical sealing ability and adaptation of three resin-based sealers to the dentine.
MATERIALS AND METHODS
A total of 66 recently extracted human maxillary anterior teeth were subjected for the study. The teeth were prepared and obturated with gutta-percha by a lateral condensation using AH Plus, Endorez and Epiphany sealers. Fifteen teeth from each group were used for the apical leakage test and the remaining five teeth from each group were used for examination under the scanning electron microscope. Data were analyzed using one-way ANOVA and the Student Newman-Keuls test.
RESULTS
Epiphany sealer showed better sealing ability and adaptation to dentine.
CONCLUSION
The Epiphany sealer has a better apical sealing ability and adaptation to dentine than the AH Plus and Endorez sealers.
目的
评估三种树脂类封闭剂对牙本质的根尖封闭能力及适应性。
材料与方法
选取66颗近期拔除的人类上颌前牙用于本研究。对牙齿进行预备，采用侧向加压法用牙胶尖充填，分别使用AH Plus、Endorez和Epiphany封闭剂。每组15颗牙齿用于根尖渗漏试验，每组其余5颗牙齿用于扫描电子显微镜检查。数据采用单因素方差分析和Student Newman-Keuls检验进行分析。
结果
Epiphany封闭剂显示出更好的封闭能力及对牙本质的适应性。
结论
与AH Plus和Endorez封闭剂相比，Epiphany封闭剂具有更好的根尖封闭能力及对牙本质的适应性。
