Benefícios e aplicabilidade clínica do uso de laser no processo de desinfecção intracanal – efeitos diretos frente a Enterococcus faecalis: revisão de literatura

Abstract

Introduction: Enterococcus faecalis is a potent microorganism involved in resistant endodontic infections and, in the face of such bacteria, the use of laser can be an efficient tool. Objective: The present study aims to evaluate the antimicrobial efficacy of laser-based therapy in the intracanal cleaning process, highlighting the fight against Enterococcus faecalis, through a literature review. Methodology: In this study, a survey of articles from 2013 to 2023 was carried out in four electronic databases (PUBMED/MEDLINE/SCIELO/LILACS), using the following descriptors: “Laser”, “Endodontics”, “Photodynamic Therapy” , and “Enterococcus faecalis”. Results: At the end of the survey, 20 articles were selected. Studies highlight that several protocols can be explored as an alternative to conventional manual irrigation, with promising results being obtained in terms of disinfectant power. However, laser application was more satisfactory as an additional modality, that is, in association with an irrigating solution, the most common being NaOCl in different concentrations. Points such as the elimination of endoxins and the increase in temperature were brought up by some authors as a way of assessing the risks and benefits of using such technology in endodontics, emphasizing the importance of establishing protocols to guarantee the safety and efficacy of the treatment. Conclusion: According to the literature review carried out, it is concluded that the laser is a promising alternative for endodontic treatment, highlighting its action against E. feacalis. However, more clinical studies are needed to confirm its efficacy as a single therapy.
