Unilateral Connation of Primary Mandibular Lateral Incisor and Canine Associated with Missing Succedaneous Teeth: Report of a Rare Case in Siblings

Abstract

Connation is one of the developmental anomalies of the dental hard tissue. The terms such as double formation, double teeth, twinned teeth, synodontia, joined teeth, or fused teeth are often used to describe connation. Connation can be defined as union of two normally separated tooth germs typically leading to one tooth less than normal in the affected arch. It may be complete or incomplete. Connation in siblings are rare and probably show a hereditary aetiology. Here, we report two cases of unilateral connation of primary mandibular incisor and canine associated with missing succedaneous permanent lateral incisor in siblings along with their diagnosis and management.
