Abstract
The development of tooth is a highly complex procedure and mastered by specific genetic
programs. Genetic alterations, environmental factors, and developmental timing can
disturb the execution of these programs, and result in various dental anomalies like
hypodontia/oligodontia, and supernumerary teeth, which are commonly seen in our clinical
practice. Advances in molecular research enabled the identification of various genes
involved in the pathogenesis of dental anomalies. In the near future, it will help
provide a more accurate diagnosis and biological-based treatment for these anomalies.
In this article, we present the molecular phenomenon of tooth development and the
genetics of various dental anomalies.
