Regression of chronic apical periodontitis after six months of control

Abstract

This study aims to describe the repair through a clinical case of an extensive periapical lesion with a diagnosis suggestive of chronic apical periodontitis.  A 28-year-old female patient was referred to the Integrated Clinic III of the Pernambuco School of Dentistry for endodontic treatment of tooth 11. Cervical and middle canal preparation was performed with manual instruments using the Crown Down technique. %.  Electronic odontometry was performed with the apical locator (Romiapex® and confirmed by radiographic odontometry. Apical preparation was done with a third-grade file and root canal filling was performed using the rolled cone technique, associated with the active lateral condensation technique and Bio-C Sealer bioceramic endodontic cement. It was verified by radiographic images in the treatment performed, that during the consultations there was a significant reduction in the periapic lesion six months after the root canal filling. It is concluded that conservative endodontic treatment is capable of determining the success of the therapy.
