Diagnosis of root fractures is generally based on clinical and radiographic presentations. This case report aims to detect horizontal/oblique root fractures in posterior teeth using a combination of conventional radiographs and cone-beam computed tomography (CBCT). Three maxillary first molars with horizontal/oblique root fractures in the palatal roots are presented. More detailed information on root fractures can be obtained using CBCT compared with conventional radiography. As such, CBCT might be a useful complementary diagnostic method to conventional radiography in cases of suspected horizontal/oblique root fractures.
根折的诊断通常基于临床和影像学表现。本病例报告旨在使用常规 X 线片和锥形束 CT（CBCT）联合检测后牙的水平/斜向根折。介绍了 3 例上颌第一磨牙腭根的水平/斜向根折。与常规 X 线片相比，CBCT 可提供关于根折的更详细信息。因此，在疑似水平/斜向根折的情况下，CBCT 可能是常规 X 线片的一种有用的补充诊断方法。
