Teeth are housed in mandible and maxilla and are known to undergo variations in clinical presentation depending on the degree of abnormality during growth and development. It is essential to identify these variations in normal anatomy so that appropriate treatment can be initiated to address the anomaly. Some normal anatomic variations are harmless and best left alone, whereas others require intervention. Radiology plays a vital role in identification of such anomalies. This article focuses on the diagnostic radiographic interpretation and strategies to include pertinent differential diagnosis. Also discussed is the importance of advanced imaging and its appropriateness in the diagnosis and interpretation.
牙齿位于下颌骨和上颌骨中，已知其临床表现会因生长发育过程中的异常程度而有所不同。识别正常解剖结构中的这些变异非常重要，以便能够启动适当的治疗来处理异常情况。一些正常的解剖变异是无害的，最好不予处理，而其他一些则需要干预。放射学在识别此类异常中起着至关重要的作用。本文重点关注诊断性放射学解读以及包括相关鉴别诊断在内的策略。还讨论了高级成像的重要性及其在诊断和解读中的适用性。
