Secondary hyperparathyroidism causing increased jaw bone density and mandibular pain: A case report

We present the case of a 32-year-old male patient complaining of recurrent mandibular pain for 3.5 years. Panoramic radiography showed increased cortical density of the mandibular lower border. Scintigraphy and SPECT-CT revealed metabolic hyperactivity in that region without pathological lymph nodes. A bone biopsy of the mandibular lower border did not show inflammation or cytological atypia. Endocrinologic investigation confirmed secondary hyperparathyroidism due to hypovitaminosis D. Several weeks after starting therapy with oral vitamin D supplements, the symptoms completely disappeared.
