摘要/Abstract

摘要： 目的:筛选出应用亚甲基蓝光动力疗法辅助根管消毒效果最优的根管预备程度。方法:体外孔板内构建粪肠球菌生物膜,以证实亚甲基蓝光动力疗法对粪肠球菌有杀菌作用。在离体牙根管中构建粪肠球菌生物膜,比较光动力疗法对于不同预备程度根管内粪肠球菌的清理效果。结果:体外建模证实光动力疗法可杀灭粪肠球菌。根管预备0.04锥度下,20号和25号根管组杀菌效果不如30号根管组;在25号根管组中,0.04锥度组杀菌结果不如0.06锥度组和0.08锥度组。结论:光动力疗法对根管中的粪肠球菌有明显杀菌作用,配合亚甲基蓝光动力疗法对根管内粪肠球菌进行清理的相对优化预备程度为0.04锥度30号和0.06锥度25号。

Abstract: Objective: To screen out the optimal degree of root canal preparation assisted by methylene blue light dynamic therapy for root canal disinfection. Methods: Enterococcus faecalis biofilm was constructed in external orifice plate to confirm the bactericidal effect of methylate blue light power on enterococcus faecalis. The photodynamic cleaning efficiency of enterococcus faecalis biofilms was compared in the in vitro root canals with different preparation levels. Results: Photodynamic therapy could kill enterococcus faecalis. At 0.04 taper of root canal preparation, the sterilization results of No. 20 and 25 root canal groups were inferior to that of No. 30 root canal group. In No. 25 root canal group, the sterilization results of 0.04 taper group were inferior to those of 0.06 taper group and 0.08 taper group. Conclusion: Photodynamic can kill the enterococcus faecalis in the root canal, and the preparation of the root canal to 0.04 taper 30 and 0.06 taper 25 is a relatively good preparation for the cleaning of enterococcus faecalis in the root canal with methyblue.
