Endodontic retreatment in case of failure. Case report.

Abstract

In medical practice, clinicians come across an increased number of endodontic treatments, which, like other dental treatments, can fail. The increase in the number of endodontic treatment resulted in an increased number of failures, their management raising complex and serious endodontic problems. The endodontic retreatment of a failure is required by the increased desire to preserve the tooth on the dental arch, thus preventing the need for dental extraction that may have adverse consequences in terms of functional and psychological effect on patients. This article presents two clinical cases that required endodontic retreatment in order to avoid the complications that could ultimately require tooth extraction. The teeth in question (a mandibular first molar and an upper central incisor) having a special importance, and a physiognomic role, the endodontic retreatment consisted in covering them in porcelain fused to the metal crowns.
