Partial bifurcation and webbed root of mandibular second premolar--an uncommon variation.

ABSTRACT

An eleven year old girl reported to J. S. S. Dental College with spontaneous pain in the left mandibular region. On examination, left mandibular second premolar was found to be hypoplastic and grossly destroyed. On radiographic evaluation, an uncommon variation of bifurcation at the apical one third of the root was seen while the contralateral tooth was normal. Treatment planning included extraction of the tooth and evaluation of the morphodifferentiation which showed a webbed appearance in the bifurcated root contrary to the radiographic finding. This webbed appearance could be due to hypomineralisation due to trauma to the developing roots from the infection of its predecessors.
