Antimicrobial photodynamic therapy for the treatment of peri-implantitis: A literature review

Aim: The aim of this article is to describe the existing scientific literature on photodynamic therapy (PDT) effectiveness for peri-implantitis treatment. Materials and Methods: A date-restricted electronic search strategy was performed in PubMed and Scopus databases. The following words were used: 'peri-implant photodynamic therapy,' 'photodynamic therapy in implantology,' 'effectives of photodynamic therapy in peri-implantitis,' 'Antimicrobial Photodynamic Therapy,' 'Photodynamic Therapy for the treatment of peri-implantitis,' and 'Mechanical debridement and photodynamic therapy in implantology.'Results: Of the 15 articles, 13 articles were selected, of which 11 were prospective and experimental studies and 2 were longitudinal. The PDT effectiveness of peri-implantitis inflammation treatment was the most reported and investigated. Conclusion: There is scientific evidence that may support the use of PDT for peri-implantitis treatments. However, even more studies would still be needed to have solid evidence.
