USE OF PHOTODYNAMIC THERAPY IN ENDODONTICS: A SYSTEMATIC REVIEW OF THE LITERATURE

Abstract

Endodontics has evolved, but challenges persist, such as bacterial resistance in the preparation. Eliminating microorganisms is crucial, but complex. Traditional methods raise concerns, driving the exploration of Photodynamic Therapy (PDT) as an alternative. The objective of this work is to analyze the use of photodynamic therapy (PDT) in endodontics. A search was carried out using the descriptors "photodynamic therapy" and "endodontics" using the DeCS search platform, applying a 5-year filter to consider more recent studies. Using the PubMed and Bvs databases (virtual health library). Current studies on photodynamic therapy (PDT) in endodontics differ in their results. Some show the effect of the photosensitizer on the adhesion of posts to dentin; others indicate the usefulness of PDT, but without isolated efficacy against certain microorganisms. In view of the research carried out, it is concluded that studies on photodynamic therapy show varied results in endodontics. Some reveal effectiveness in disinfecting root canals, while others point out limitations, such as lack of influence in certain aspects. Standardization of studies and more comparative research are needed to fully understand their role.
