A definitive diagnosis of vertical root fracture (VRF) is often a challenging task for clinicians. This is because two dimensional periapical radiographs are usually unable to detect the fracture line due to the direction of the X-ray beam. This report presents a set of 3 cases of endodontically treated teeth that were diagnosed with VRFs based on findings from clinical, radiographic, and cone-beam computerized tomographic (CBCT) examinations. After extraction, VRFs were confirmed in all cases. The presence of periodontal pockets or other signs which would compromise the correct diagnosis could not be detected in all three cases. Fracture lines were only visible with the aid of CBCT which provided useful information for the diagnosis and management of VRF. However, the clinical and radiographic data should not be discarded, but used in conjunction with CBCT.
对于临床医生而言，明确诊断垂直根折（VRF）往往是一项具有挑战性的任务。这是因为由于X射线束的方向，二维根尖片通常无法检测到骨折线。本报告介绍了一组3例经牙髓治疗的牙齿，这些牙齿根据临床、影像学和锥形束计算机断层扫描（CBCT）检查结果被诊断为垂直根折。拔牙后，所有病例均确诊为垂直根折。在所有三例病例中均未检测到会影响正确诊断的牙周袋或其他迹象。骨折线仅在CBCT的帮助下可见，CBCT为垂直根折的诊断和治疗提供了有用信息。然而，临床和影像学数据不应被丢弃，而应与CBCT结合使用。
