Radiographic patterns of multiple myeloma in the jawbones of patients treated with intravenous bisphosphonates.

Background: The purpose of this study was to evaluate whether intravenous (IV) bisphosphonate (BP) therapy can change the radiographic patterns of multiple myeloma (MM) in the jawbones.

Methods: The authors evaluated panoramic radiographs obtained from 188 patients with MM for the presence of solitary osteolytic lesions, multiple osteolytic lesions, diffuse osteoporosis, diffuse sclerosis, lamina dura abnormalities, nonhealing alveolar sockets, and bone sequestration. The authors compared results obtained from patients treated with IV BPs with those obtained from patients who had never been exposed to BPs.

Results: Multiple osteolytic lesions (P = .001), diffuse osteoporosis (P = .001), and diffuse sclerosis (P = .0036) occurred more often in the mandible in both groups. Solitary osteolytic lesions occurred less frequently in the BP group (P = .0078). Lamina dura abnormalities (P = .0006) and nonhealing alveolar sockets (P = .0021) were associated with BP treatment.

Conclusions: IV BP therapy changes the radiographic patterns of MM in the jawbones. Conclusions: The effect of BPs in the maxillofacial area is a matter of concern for health practitioners because this type of medication causes several alterations of the jawbones in patients with cancer.
