[Dentomaxillary destructions in oxalosis].

Oxalosis, a rare metabolic disorder, leads to excessive formation of oxalate and deposition of calcium oxalate crystals in the tissue. This leads to renal insufficiency with resulting secondary hyperparathyroidism and myelofibrosis. In a 27 year old female patient, extensive destruction of the maxilla, mandible and teeth was observed which has not yet been described and which led to the loss of all teeth.
