Roentgenographic manifestations of maxillomandibular renal osteodystrophy

We examined 30 male chronic hemodialysis patients and 18 male controls without known bone or renal disease to determine the utility of maxillomandibular, non-dominant hand, shoulder and pelvis films in the evaluation of renal osteodystrophy. We used panoramic periapical radiographs to examine the maxilla and mandible and sensitive rapid processing films for the hand, shoulder and pelvis. Films were evaluated by experienced personnel without knowledge of the patients. There were significant differences between patients and controls in creatinine, urea nitrogen, total protein, albumin, alkaline phosphatase and phosphorus. Twenty-three patients had abnormal hand radiographs and 22 patients had abnormal jaw radiographs (p less than 0.05 vs. controls). Four patients had changes in the hands, but not in the jaw; 4 had opposite findings. Changes in the jaw tended to be more severe than in the hands in those with involvement of both. We concluded that dental and hand radiography are good screening techniques for evaluating bone disease. They may be useful in evaluating treatment for renal osteodystrophy.
