A case of oromandibular-digital hypogenesis syndrome

The oromandibular-digital hypogenesis syndrome is characterized by failure of development of the intraoral region and the distal extremities. A 12 year old female with an anomaly of the lingual fraenum, hypodontia of the lower incisors and defective fingers and toes was referred to our clinic. The aetiology of the disorder is still obscure. The author has reviewed the literature and discusses the morphological variation of the lingual fraenum.
