Abstract
OBJECTIVE: The purpose of this study was to evaluate the most frequent radiographic appearance of bony lesions associated with vertically fractured roots of endodontically treated maxillary premolars. STUDY DESIGN: The radiographic features of 102 endodontically treated teeth and their periradicular areas (51 with and 51 without vertically fractured roots) were evaluated and compared. RESULTS: The predominant appearance of the periradicular area in the teeth with vertically fractured roots was the "halo" lesion (57%); by contrast, in the non-vertically fractured roots group, a "periapical" radiolucent lesion was most frequently found (55%). Angular bone loss (14%) and periodontal radiolucency (14%) were also typical radiolucent lesions in the vertically fractured teeth. CONCLUSIONS: "Halo" lesion, perilateral radiolucency, and angular resorption of the crestal bone, combined with diffuse or defined but not corticated borders, indicated a high probability of vertical root fracture in maxillary premolars.
