Severe hypodontia or even adontia in children are very rare conditions, most often associated with congenital syndromes such as Down syndrome (trisomy 21) [46] or ectodermal dysplasia [53].
This adontia has so far been confined or noted only in some members of the subfamily Mylodontinae; specifically in the Plio-Pleistocene genera of Mylodon from South America and Paramylodon from North America (McAfee, 2007, 2009).
There was partial adontia with only one conical incisor tooth.
