Hyperdontia is an odontostomatologic anomaly characterized by an excess in tooth number, both erupted and no nerupted. It can be described as “real” if determined by an increased number of teeth, otherwise it is “false” if caused by a delay in shedding of deciduous teeth beyond the transition period 1, 2, 3, 5. In one of his studies, Tomes suggested a no-menclature for teeth in excess3: they were defined as “supplementary” if they present a normal morphology and as “supernumerary” if they present morphologic and volumetric anomalies. Supernumeraries are classified according to morphology 3 into conical,
