Introduction: Effective decontamination of the root canal system is key to the success of endodontic treatment. Photodynamic Therapy (PDT) may be an important tool in the reduction of root canal pathogens. Objectives: This study aimed to review the literature on the use of this therapy in Endodontics, and which clinical protocol has been used. Methods: A literature search was carried out using the following databases: PubMed and Scielo, and the following key-words: endodontics; photodynamic therapy; photodynamic therapy endodontics; light-activated disinfection root canal; light activated disinfection endodontics; photo-activated disinfection endodontics; photo-activated disinfection. Results: We selected 18 articles which fit the inclusion criteria: original and relevant articles, clinical and laboratory research, in permanent human teeth, as well as articles reporting the use of photodynamic therapy as a single or adjunct treatment to root canal disinfection, in addition to its efficacy in bacterial reduction. Conclusions: PDT has been shown to be an effective method in microbial reduction of root canals; however, it should be used as an additional method to conventional treatment.
