摘要/Abstract

摘要： 目的: 研究Nd:YAG根管荡洗技术对纤维桩粘接性能的影响。方法: 20颗单根离体牙样本根管机械预备后按照终末荡洗技术分为两组:2.5%次氯酸钠针头冲洗组,2.5%次氯酸钠Nd:YAG根管荡洗组。常规根充以及纤维桩粘接后,对样本纤维桩部分片切并进行推出实验,同时观察和分析其断裂模式。结果: Nd:YAG结合次氯酸钠荡洗组纤维桩粘接强度明显高于次氯酸钠针头冲洗对照组;主要的断裂模式为混合断裂模式。结论: Nd:YAG辅助荡洗技术能够提高纤维桩粘接强度。

Abstract: Objective: To study the effect of Nd:YAG laser-activated root canal irrigation on fiber post bonding.Method: Twenty single-rooted teeth were collected and divided into two groups according to the final irrigant activation protocols after root canal preparation: conventional syringe irrigation with 2.5% NaOCl and Nd:YAG laser irrigation with 2.5%NaOCl.After root canal obturation and fiber post bonding, the specimens were sectioned and subjected to push-out test.The fractured mode was observed.Results: The bonding strength of Nd:YAG laser-activated irrigation group was higher than that of control group.Analysis indicated that the predominant failure mode was the mixed type.Conclusion: Nd:YAG laser-activated irrigation can improve the bonding strength of fiber posts.

Key words: Nd:YAG, Laser-activated irrigation, Fiber post, Bonding strength
