Hypocalcemia due to increased phosphate retention and decreased calcium absorption. Body sees hypocalcemia and tries to raise serum calcium = secondary hyperparathyroidism and caclcium is removed from bone stores = renal osteodystrophy
Walk through OHI and dental management with a patient before they receive chemotherapy/radiotherapy.
Cancer
