Endodontia regenerativa em dentes maduros

Abstract

Conventional endodontic treatment is the standard therapy for teeth with irreversible pulp infection or inflammation, allowing previously condemned teeth to remain in function. As an alternative, regenerative endodontic treatments (RET) have been used successfully in the therapy of immature permanent teeth for years and currently also in mature teeth. RET is based on tissue engineering principles, being able to promote periapical lesion healing, continued root development and pulp sensitivity. The technique has disadvantages, such as the risk of staining the dental crown and the diversity of protocols for use, many of which are still being studied. A major advantage of RET over TEC in mature teeth is the filling of the canal with vital tissue, as well as overcoming old limitations of conventional endodontics. As a disinfectant, NaOCl is the most used solution, in concentrations between 0.5 and 6%, associated or not with EDTA. For the formation of the scaffold, BC cells were the most cited among others. There are several reports of successful cases using the technique that basically consists of partial or total removal of the inflamed or necrotic pulp, application of antimicrobials, stimulation of bleeding with the construction of a matrix (scaffold) and sealing with cement, preferably bioceramic. However, the number of professionals who know, master and perform this treatment modality is still limited, which could be changed in the face of more defined treatment protocols and greater scientific evidence of the success of this method.
