Increased uptake of Tc-99m-methylene diphosphonate in the area of jaw is a common finding on the whole body bone scan. To study its incidence, causes and clinical significance, we performed static anterior and bilateral head views on 52 consecutive patients, followed by a dental examination and a panoramic radiograph. We demonstrated that increased uptake of bone tracer in the area of jaw was observed at a high incidence, as well as its characteristic distribution. The mainly causes are some common dental diseases. These findings would better guide the diagnosis and treatment for patients.
