This study aimed to evaluate the effects of bisphosphonates on the mandibular bone. Bisphosphonates are drugs which are commonly used in the treatment of many diseases related to bone metabolism such as osteoporosis, breast cancer capable of bone metastasis, prostate and lung cancer and bone cancer such as multiple myeloma. Our study group consisted of a total of 100 panoramic radiographs which were obtained from the examinations of 50 individuals using bisphosphonate and 50 individuals in the control group who applied for routine dental examination to the Department of Oral and Maxillofacial Radiology of Akdeniz University Dentistry Faculty between years 2015 and 2016.The calculations of the mandibular cortical thickness (MCT), mandibular cortical index (MCI), panoramic mandibular index (PMI), condylar angle (CA), gonial angle (GA), antegonial angle (AGA), antegonial depth (AGD) and antegonial index (AGI) were made for each patient. It was found that both left and the right MCT and only the left PMI were affected by age. Only the left AGA and both the left and right MCT and AGD were affected by gender. The left and right AGI measurements of the patients using bisphosphonates were statistically lower than those of the individuals in the control group. Our results suggested that bisphosphonates had various effects on the jaw bones. However, further comprehensive studies need to be made to evaluate the long- term effect of bisphosphonates on bone metabolism.
