Resorption of Condyloid Process of Mandible

Abstract

Roentgenographic evidence of bone disease in patients with chronic renal failure is being observed with increasing frequency as the lives of such patients are prolonged with maintenance hemodialysis. 1 The type and severity of bone disease in patients with renal failure are probably related to the degree and duration of renal insufficiency and may be influenced by the dietary habits of the patients. 1-4 Although both the genesis and pathological lesions of renal osteodystrophy are complex, the predominant osseous abnormality in patients treated with maintenance hemodialysis is markedly enhanced bone resorption 5 induced by the high levels of circulating parathyroid hormone. 6 The roentgenographic manifestations of secondary hyperparathyroidism are granularity and mottling of the skull, subperiosteal bone resorption of the phalanges, distal end of ulna and femur, and upper end of tibia, and resorption of the lateral ends of the clavicles. 7 Occasionally, brown tumors and cysts may be seen.
