title: Teeth erupted from the buccal mucosa: simple odontogenic choristoma or accessory teeth?
abstract: The eruption of developed teeth from the buccal mucosa is a rare phenomenon in the head and neck region. Such phenomena are possibly choristomas, tumorlike masses of histologically normal tissue occurring in an abnormal position. However, the accurate classification of this abnormality remains debatable. This report describes a case of a congenital, maldevelopmental, and noncystic lesion in a 4-year-old girl without other anomalies. To the authors' knowledge, this is the first case of multiple supernumerary teeth forming in the buccal and zygomatic regions.
