PHOTODYNAMIC THERAPY ASSOCIATED WITH ROOT CANAL TREATMENT

Abstract

Photodynamic therapy (PDT) associated with root canal treatment has been considered a promising approach in modern endodontics. However, complete disinfection of root canals has remained a challenge, even with the use of conventional antimicrobial agents. In this context, the problematic of this article consisted of the following question: What were the limitations of conventional endodontic disinfection techniques and how could PDT overcome them? The main objective was to analyze the effectiveness of PDT in the endodontic disinfection process. The specific objectives included understanding the principles and mechanisms of action of PDT, evaluating studies on its application and identifying the need and requirements for an effective application in endodontics. This literature review was carried out with a qualitative and descriptive approach, using renowned databases such as Lilacs, Medline through the virtual health library, PubMed and Scielo. Although empirical results were not available at the time due to the prospective nature of this research, considerations based on the theoretical framework and the adopted approach provided a solid basis for inferring the potential positive implications of the application of Photodynamic Therapy (PDT) in endodontics. Thus, the analysis contributed significantly to an updated understanding of PDT as a promising tool in root canal treatment, highlighting its potential to improve clinical outcomes and reduce the incidence of persistent infections.
