Pyle's disease: an incidental finding in a routine dental patient.

Pyle's disease (PD) or metaphyseal dysplasia is an extremely rare genetic disorder, transmitted as an autosomal recessive trait. The peculiarity of the disease is that the striking radiographic manifestations contrast with the relatively normal clinical features. The oral findings and radiographic features of the disease are not well documented. The present paper describes the radiographic features of Pyle's disease in a 17-year-old girl and draws attention to the findings in the jaw bones.
