Amelogenesis imperfecta with growth hormone deficiency in a 12 year-old boy.
Amelogenesis imperfecta (AI) is a diverse group of hereditary disorders that are characterized by a defect in the formation of the tooth enamel and a high degree of clinical diversity. X-linked, autosomal dominant and recessive inheritance have been demonstrated. Growth hormone (GH) has an effect on bone and soft tissue development. Dental and facial abnormalities associated with pituitary dwarfism have been reported, but GH deficiency with AI is very rare. We describe a 12 year-old pre-pubertal boy who was referred to our hospital with teeth deformities and growth retardation. His teeth had brown-yellow pigmented surfaces, and dental examination showed extensive enamel deficiency in his permanent teeth. He also had severe growth retardation; height SDS was -3.6. Laboratory examinations showed reduced GH levels, and he was diagnosed as having idiopathic isolated GH deficiency and AI.
