Terapia fotodinâmica associada ao tratamento endodôntico: revisão de literatura

Abstract

The complex anatomy of the root canals makes it difficult or even impossible to disinfect in some regions of this network of channels. It is within this context, from the impossibility of disinfection, that new approaches have been proposed with the aim of enhancing disinfection. Among these approaches, the photodynamic therapy emerges as a promising technique and is the object of extensive research in dentistry, in order to eliminate microorganisms resistant to mechanical chemical preparation. This technique is based on the following triad: light source with specific length, photosensitizer and oxygen, generating harmful phototoxic products to the target cells. It is considered a quick technique, easy to apply, painless and can be used in single or multiple sessions, with the advantage of not inducing bacterial resistance as well as not causing systemic effects. The present study aimed to evaluate, through a literature review, the effectiveness of the association of photodynamic therapy with conventional endodontic treatment. At the end, it was possible to obtain the following conclusions: there is a disinfection difficulty in the endodontic treatment due to the complexity of the root canal system, with the possibility that photodynamic therapy, when associated with conventional treatment, will promote increased success rates of this.
