FREITAS, Pollyanna Queiroz; RABELO-JUNIOR, Paulo Maria Santos; ALVES, Claúdia Maria Coelho y SOUZA, Soraia de Fatima Carvalho. The diagnostic challenge of vertical root fracture in endodontically treated teeth: a case report. Rev. odonto ciênc. [online]. 2012, vol.27, n.1, pp. 82-86. ISSN 1980-6523. http://dx.doi.org/10.1590/S1980-65232012000100016.
PURPOSE: To present the diagnostic challenge of a clinical case of vertical root fracture (VRF) in an endodontically treated mandibular left lateral incisor and discuss the diagnostic methods employed to achieve the conclusive diagnosis. CASE DESCRIPTION: At 16 months after endodontic treatment, a 60-year-old female patient reported pain during mastication. Clinically, she presented with an active distolingual fistula and a probing depth of 9 mm on the distal aspect of tooth 32. A radiographic examination indicated pear-shaped distal bone loss. The fistula was mapped, which confirmed that the lesion had a periodontal origin. A diagnostic hypothesis of a VRF was established. Exploratory surgery revealed the VRF on the distolingual aspect of the root without separation of the root fragments. CONCLUSION: Knowledge of the diagnostic aspects and the correct interpretation of radiographic images was enough to establish the diagnostic hypothesis of a VRF. However, the conclusive diagnosis was only confirmed during exploratory surgery.
