Cleidocranial dysplasia is an inherited skeletal anomaly that affects primarily the skull, clavicle, and dentition, which can occur spontaneously, but most are inherited in autosomal dominant mode. The skull findings are brachycephaly, delayed or failed closure of the fontanelles, presence of open skull sutures and multiple wormian bones with pronounced frontal bossing. The syndrome is notable for aplasia or hypoplasia of the clavicles. The neck appears long and narrow and the shoulders markedly droop. Oral manifestations exhibit a hypoplastic maxilla with high-arched palate. Crowding of teeth is produced by retention of deciduous teeth, delayed eruption of permanent teeth, and the presence of a large number of unerupted supernumerary teeth. We report a case of CCD in a 12-year-old girl who presented with an unaesthetic facial appearance, unerupted permanent dentition with hearing loss.

Keywords: Cleidocranial dysostosis, delayed tooth eruption, hearing loss, hypoplastic clavicle, supernumerary teeth.
