Nowadays, cone beam computed tomography (CBCT) are commonly used in dentistry with an advantage about significantly lower dose comparing with CT-Scanner. Utilizing CBCT images which are indicated in dentistry like orthodontics can help diagnose diseases beyond dentistry field. One rare phenomenon can be seen in maxillary sinus, which is often overlooked by dentists, is ectopic teeth.
This article describes one orthodontic case found accidentally an ectopic tooth in maxillary sinus by inspecting CBCT images.
Dentists and oral radiologists should carefully inspect non-dental structures, like maxillary sinus, even its distance from the dentoalveolar region, especially in asymptomatic patients.
如今，锥形束计算机断层扫描（CBCT）在牙科领域被广泛应用，其优势在于与CT扫描仪相比剂量显著更低。利用牙科领域如正畸治疗中所使用的CBCT图像有助于诊断牙科领域以外的疾病。在上颌窦中可以看到一种罕见现象，即异位牙，这一现象常被牙医忽视。
本文描述了一例正畸病例，通过检查CBCT图像意外发现上颌窦中有一颗异位牙。
牙医和口腔放射科医生应仔细检查非牙齿结构，如上颌窦，即使其距离牙槽区域较远，尤其是对于无症状患者。
