光动力疗法应用于根管消毒研究进展

摘要/Abstract

摘要：

光动力疗法主要依靠光敏剂活化产生的活性氧来杀伤细菌细胞，可作为一种安全、有效的消毒方法应用于根管治疗。光动力疗法的杀菌效果受到光敏剂及其浓度、光源与照射参数、暗处理时间、光纤的使用、细菌的种类与状态、组织抑制因子等多方面影响。而光动力疗法对细菌生物膜的消毒效果也有望得到提高。

Abstract:

Abstract：As a safe and effective strategy of root canal disinfection，photodynamic therapy mainly relies on the reactive oxygen species generated by excited photosensitizer to kill cells of bacteria. The antibacterial efficacy of photodynamic therapy is affected by many variables and parameters，while the antibiofilm efficacy of it remains to be improved.

Key words: photodynamic therapy, photosensitizer, reactive oxygen species, biofilms
