The presence of the mesiodens in the permanent dentition is well documented. Mesiodens in the permanent dentition show great variation and are classified accordingly.
Possible explanation for the less frequent reporting of deciduous supernumerary teeth includes infrequent detection by parents, as the spacing frequently encountered in the deciduous dentition may be utilized to allow the supernumerary tooth or teeth to erupt with reasonable alignment. Also, many children have an initial dental examination following the eruption of the permanent anterior teeth so anterior deciduous teeth which have erupted and exfoliated normally would not be detected [9].
Numerous classifications have been proposed in the literature to classify supernumerary with varied acceptance. No single classification is adequate and is used according to the convenience.
The classifications are based on location; morphology, axial inclination, and other criterion are used for classification of such teeth. Sometimes the presence of supernumerary teeth is seen in developmental syndromic cases such as cleft lip, and palate, cleidocranial dysostosis, Down’s syndrome and Gardener’s syndrome. Other cases where syndromic involvement is seen are enumerated in Box
