Comparative efficacy of orthopantomography and helical computed tomography in diagnosis of the jaw osteonecrosis in patients with myeloma disease
The purpose of the work was to investigate informativity and efficacy of radiation diagnosis of osteonecosis of jaw bones in patients with myeloma disease treated with bisphosphonates (BP), using orthopantomography and helical computed tomography (HCT) of the jaws. The study involved 53 patients with MD who together with chemotherapy were administered bisphosphonates (31 women, 58.5 % and 22 men, 41.5 %). Mean duration of therapy was from 6 to 57 months. The state of the lower jaw was investigated using orthopantomography and helical computed tomography. Orthopantomography allowed to reveal the foci of osteonecrosis in the lower jaw, HCT allowed visualizing various grade manifestations of osteonecrosis.
