title: [Vertical root fractures in endodontically treated teeth part I: clinical and radiographic diagnosis].
abstract: A correct and quick diagnosis of endodontically treated vertically fractured teeth is important for two main reasons: (1) the differential diagnosis between the clinical and radiographic appearance of periodontal disease and endodontic failures, and (2) the delay in making the correct diagnosis will result in rapid loss of supporting bone, especially on the buccal side. Typical clinical signs in the maxillary and mandibular premolars and mesial root of the mandibular molars, which are the most susceptible roots and teeth, for fracture are a highly located sinus tract and a deep bony defect along the root facing the fracture line. In the maxillary and mandibular premolars and the mesial root of mandibular molars, typical bony radiolucencies are the halo, vertical and periodontal types. Radiolucency in the bifurcation was typical in vertical root fractures of mandibular molars.
