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.
