Localized Microdontia: Unilateral Peg Shaped Mandibular Central Incisor

Diverse morphological, structural and tooth number aberrations can occur within human dentition secondary to genetic and epigenetic influences which can be manifested as microdontia, macrodontia, hypodontia, oligodontia etc. Microdontia is much more common than macrodontia. Non-syndromic microdontia is not often noted, especially in the permanent mandibular incisors. This is a detailed description of a case of a non-syndromic peg shaped permanent mandibular central incisor in a 9 year old male. Early detection of dental development anomalies is very important, as they may lead to many complications. Documentation of these discrepancies helps in assessing the evolutionary structural and morphological changes in human dentition.
