However, the clinical and radiographic characteristics of VRFs are not completely known. Methods A total of 65 teeth with 68 vertical fractured roots in 58 Chinese patients were investigated. The clinical examination records and radiographic images were reviewed in detail. Results A total of 24 male (41.38%) and 34 female (58.62%) patients aged 25–90?years (average = 57?years) were included; 51 (87.93%) and 7 (12.07%) patients exhibited 1 tooth and 2 teeth with VRFs, respectively, in the dentition. VRFs occurred mainly in the mesial root (20 roots, 57.14%) of the mandibular molars (29 teeth, 44.62%). Clinically, teeth with VRFs usually presented a periodontal probing depth >5?mm (44 teeth, 91.67%, P?.001) with a prosthesis (55 teeth, 84.62%, P?.001) and a relatively intact dentition (42 patients exhibited <4 missing teeth in the dentition, 77.78%, P?.001). Most of the nonendodontically treated VRFs exhibited attrited occlusal surfaces. Radiographic characteristics of the teeth with VRFs were typically associated with prior root canal treatment (56 teeth, 86.15%, P?.001), periodontal bone loss (62 teeth, 95.38%, P?.001), apical bone loss (52 teeth, 80.00%, P?.001), and periodontal ligament widening (61 teeth, 93.85%, P?.001). The mesial roots of the mandibular molars were most susceptible to VRFs in both endodontically and nonendodontically treated teeth. Conclusions These results elucidated some clinical and radiographic and diagnostic features that facilitate VRF identification. ? 2016 American Association of Endodontists |
