Conventional radiographs provide important information for dental disease diagnosis. However, they represent 2-D images of 3-D objects with significant structure superimposition and unpredictable magnification. Cone beam computed tomography, however, allows true 3-D visualization of the dentoalveolar structures, avoiding major limitations of conventional radiographs. Cone beam computed tomography images offer great advantages in disease detection for selected patients. The authors discuss cone beam computed tomography applications in dental disease diagnosis, reviewing the pertinent literature when available.
传统的X光片为牙科疾病诊断提供了重要信息。然而，它们呈现的是三维物体的二维图像，存在显著的结构重叠和不可预测的放大率。而锥形束计算机断层扫描能够实现牙槽结构的真实三维可视化，避免了传统X光片的主要局限性。锥形束计算机断层扫描图像在特定患者的疾病检测中具有很大优势。作者讨论了锥形束计算机断层扫描在牙科疾病诊断中的应用，并在有相关文献时进行了综述。
