Terapia fotodinâmica e sua viabilidade como coadjuvante no retratamento endodôntico: revisão de literatura

Abstract

The endodontic treatment is a dental procedure that aims to keep a pulpless dental element functioning in the oral cavity. It is a complex treatment made up of several steps, and its correct execution aims at the treatment's success. However, there are instances in which, due to certain factors, such treatment may not result in the expected parameter, thus configuring failure and requiring endodontic retreatment. Among several options found in the literature for the resolution of cases of failure, there is a discussion about the antimicrobial photodynamic therapy being a viable method when used as an adjunct to the conventional treatment of chemical-mechanical preparation. To construct this article, a search was carried out for papers available in the Scielo (Scientific Electronic Library Online), MEDLINE (Medical Literature Analysis and Retrieval System Online) and LILACS (Latin American and Caribbean Literature in Health Sciences) databases. The objective of this research is to evaluate the antimicrobial Photodynamic therapy’s efficacy as an adjuvant to the conventional endodontic treatment and retreatment protocols. It was observed that the antimicrobial photodynamic therapy is effective in eliminating the main bacteria responsible for the failure of endodontic treatment, Enterococcus faecalis, without causing bacterial resistance. The antimicrobial photodynamic therapy is viable in its use as an adjunct in cases of endodontic retreatment.
