SUPERNUMERARY TEETH
Channel: DENTISTRY ’N MORE
Date: 25/07/2021

A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch.

Etiology

The etiology of supernumerary teeth is not completely understood. Various theories exist for the different types of supernumerary. One theory suggests that the supernumerary tooth is created as a result of a dichotomy of the tooth bud.
 Another theory, well supported in the literature, is the hyperactivity theory, which suggests that supernumeraries are formed as a result of local, independent, conditioned hyperactivity of the dental lamina. Heredity may also play a role in the occurrence of this anomaly, as supernumeraries are more common in the relatives of affected children than in the general population. However, the anomaly does not follow a simple Mendelian pattern
