Globodontia in the Otodental Syndrome: A Rare Defect of Tooth Morphology Occurring with Hearing Loss in an Eight-Year-Old

Dent Update. 2015 Dec;42(10):927-30, 932. doi: 10.12968/denu.2015.42.10.927.

Abstract

Otodental syndrome is a hereditary disorder comprising globodontia and sensorineural hearing loss. Globodontia is characterized by distinctively bulbous, enlarged crowns of molar and primary canine teeth. Anomalies including taurodontism and hypodontia also occur. We report on the dental treatment and multidisciplinary management of an eight-year-old girl with this rare condition. Referral to Clinical Genetics and Oral Pathology was instrumental in establishing a diagnosis of otodental syndrome for this young patient and her mother, who had similar dental defects. CPD/Clinical Relevance: To increase awareness among practitioners of this rare dental disorder and highlight the need for multidisciplinary management of such cases.
