Horizontal root fractures (HRF) usually affect anterior teeth of male patients as a result of trauma. The consequences can be complex because of combined damage to different tissues, but it has been reported that root fractures undergo healing in majority cases. Diagnosis of HRF must be based on clinical findings, sensibility tests, and radiographic examination. The cone-beam computed tomography (CBCT) has already been proven to be superior among other radiographic modalities for diagnostic imaging of root fractures. However, CBCT in these cases needs to be used in a careful manner, and only when the radiation exposure should be justified by the potential diagnostic benefits and improvement of the treatment results. This case report describes a case of spontaneously healed horizontal root fracture with displacement of the fragments and discusses the usefulness of CBCT in the follow-up of root fractures cases.
水平根折(HRF)通常因外伤而累及男性患者的前牙。由于不同组织的联合损伤,其后果可能很复杂,但据报道,大多数情况下根折可自行愈合。HRF的诊断必须基于临床检查结果、敏感性测试和影像学检查。锥形束计算机断层扫描(CBCT)已被证明在根折的诊断成像方面优于其他影像学检查方法。然而,在这些病例中使用CBCT时需要谨慎,只有当潜在的诊断益处和治疗效果的改善能够证明辐射暴露合理时才可使用。本病例报告描述了一例碎片移位的水平根折自发愈合病例,并讨论了CBCT在根折病例随访中的作用。
