Developmentally missing teeth may also be the result of numerous independent pathological mechanisms that can affect the orderly formation of the dental lamina, failure of a tooth germ to develop at the optimal time, the lack of necessary space imposed by a malformed jaw, and a genetically determined disproportion between the tooth mass and the jaw size. Clinically, hypodontia in the permanent dentition, excluding the third molars, is found in 3-10% of the population. Hypodontia is more frequently found in Asians and Native Americans. One of the commonest forms of localized microdontia is that which affects the maxillary lateral incisor, a condition called Peg laterals. The next tooth which can be affected is the third molars. Few cases of microdontia in canines have been reported. The following article throws light on the Concomitant occurrence of hypodontia and microdontia in a single case.
