摘要： ［摘要］口腔种植体周围炎是发生在种植体周围的炎症过程，特征为软组织炎症及支持骨的丢失。光动力疗法是利用可见光、近红外或紫外光驱动，通过光敏剂退激产生激发态单线态氧导致多种生物分子氧化产生光动力，对于致病菌具有强烈的杀灭作用。近年来，光动力疗法在口腔种植体周围炎控制中有所应用。本文从种植体周围炎治疗中应用激光，光敏剂分类，及光动力作用机制作一综述。

Abstract: Peri-implantitis is a chronic infectious disease that can affect peri-implant tissues such as gingiva and supporting bone, compromising the osseointegration prognosis. Photodynamic therapy is based on the principle that a photosensitizer can be activated by light of a suitable wavelength, producing singlet oxygen and other reactive agents which are extremely toxic to certain cells and bacteria. This article mainly elucidates light sources, photosensitizers and molecular mechanism involved in peri-implantitis treatment.
Key words: photodynamic therapy, photosensitizer, peri-implantitis
