Associação entre clareamento interno e restaurações em resina composta na reabilitação estética de dentes escurecidos despolpados: relatos de casos clínicos

Abstract

Tooth discoloration in pulpless teeth is a common aesthetic alteration that can impact patients' self-esteem. Internal bleaching represents a minimally invasive approach to restoring the natural color of these teeth, performed using various techniques, including inside-out, walking bleach, and mixed techniques. Furthermore, composite resin restorations are frequently used to even out the color and restore aesthetic harmony to the smile. This study reports the clinical sequence of two cases of tooth discoloration in endodontically treated maxillary central incisors. In the first clinical case, the inside-out internal bleaching technique was used, while in the second, the mixed technique was chosen. In both cases, after bleaching, aesthetic composite resin restorations were created to achieve a satisfactory functional and aesthetic result. However, in case 1, a reinforcement technique with polyethylene fiber tape was necessary to optimize the tooth's structural strength. The results showed that internal bleaching is a minimally invasive and low-cost alternative, effective in the aesthetic recovery of devitalized teeth and, when associated with restorative techniques, is capable of satisfactorily meeting functional and aesthetic demands.
