Primary double teeth in siblings: A report

Abstract

Double teeth are developmental malformations affecting both primary and permanent dentition. This article describes primary double teeth in both the siblings of a family. A 5-year-old boy had a bilateral distribution of anomaly involving lower lateral incisor and canine. Radiographic analysis revealed that his right mandibular permanent lateral incisor was missing. His sister, a 3½-year-old girl, also had double teeth affecting mandibular left lateral incisor and canine. She displayed no other dental anomaly. The boy presented shovel-shaped maxillary permanent central incisors. Family involvement of double teeth is very rare. Double teeth in siblings and simultaneous occurrence of multiple dental anomalies probably show a hereditary etiology.
