Most of the reported data on dental anomalies in Indian populations are case reports of supernumerary teeth, supernumerary root, hypodontia, double teeth, and talon cusps.
Supernumerary root in deciduous dentition is very rare and occurs most commonly in mandibular molars and in canines.
Supernumerary root is a developmental condition and may involve any tooth.
In the permanent dentition supernumerary roots are not uncommon; with normally single-rooted permanent premolars and canines being particularly affected.
Other researchers have suggested that fusion or gemination may be related to the clinical presentation of supernumerary roots.
The findings of Morrow and Hylin, whose primary central incisors all demonstrated bifurcation only in the apical fourth of the roots, suggest that the potential for developing supernumerary roots is present throughout the course of root elongation.
Also supernumerary root in primary teeth may have potential of interference with eruption of the succedanuous teeth.
6 If during dental development the epithelial sheath of Hertwig is disrupted or folded, supernumerary roots and accessory root canals may be formed.
