Twinning is usually asymptomatic and is associated with poor esthetics, caries, malocclusions, arch-length discrepancies, periodontal disease, hyperdontia or hypodontia of the permanent successors, and eruption abnormalities. The present case report describes the management of a carious necrotic twinned primary central incisor followed up for one year. Twinning anomaly is characterized by the presence of mirror image teeth.
