An uncommon tooth fusion of mandibular primary lateral incisor with canine

Abstract

Fusion is a congenital disturbance affecting primary dentition mostly during morpho differentiation of the primary tooth germs. Fusion leads to the union of two or more primary teeth by the enamel and dentin while the pulp and roots remain separate. These abnormalities may be unilateral or bilateral. Prompt diagnosis and a treatment plan in such anomalies may help to overcome problems concerning aesthetics, caries susceptibility and space management. This report describes a case of unilateral fusion of the primary mandibular lateral incisor and canine and aims to evaluate any associated pathology.
