Developmental Disorders Affecting Jaws

Dent Clin North Am. 2016 Jan;60(1):39-90. doi: 10.1016/j.cden.2015.08.002.


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.
