maxillary central incisor with two roots: a case report

a 16 year old female was referred to an oral and maxillofacial radiologist for evaluation of a radiolucent area at mesial radicular aspect of right maxillary central incisor which was detected accidentally during pre-orthodontic treatment check ups. clinical examination showed no particular signs or symptoms except for slightly tenderness to lateral percussion. second radiograph with altered horizontal angulations showed a mesial supernumerary root which the radiolucency seemed to be associated with that. in order to treat the tooth, the composite filling was removed and canals were cleaned, shaped, and obturated by lateral condensation technique.
