Cone-beam computed tomography (CBCT) provides accurate anatomical details in three-dimensional and multiplanar reformation images for diagnosis and treatment planning. We examined one surgical specimen of medication-related osteonecrosis of the jaw (MRONJ) by CBCT. CBCT images of the surgical specimen of MRONJ showed osteolytic changes in the jaws, sclerotic lesion, and sequestrum separation. Furthermore, high-resolution mode (tube voltage, 90.0 kV; tube current, 4.00 mA; rotation time,16.8 s; field of view, 56 mm × 56 mm; thickness, 0.099 mm) was sharper than standard mode (tube voltage, 90.0 kV; tube current, 4.00 mA; rotation time, 16.8 s; field of view, 81 mm × 81 mm; thickness, 0.144 mm) and high-density mode (tube voltage, 90.0 kV; tube current, 4.00 mA; rotation time, 33.5 s; field of view, 81 mm × 81 mm; thickness, 0.144 mm). We showed that CBCT, especially the high-resolution mode, is useful for the evaluation of surgical specimen of the jaw, such as MRONJ. This report can be used for reference in future studies and in clinical settings.
