Why is dental evaluation important before initiating high-dose bisphosphonates?

• A. To reduce osteonecrosis of the jaw risk; dental issues should be addressed prior to therapy.
• B. To check blood sugar.
• C. Dental evaluation unnecessary.
• D. To determine color of teeth.

Answer: (B)

Starting high-dose bisphosphonates requires careful dental assessment because these drugs suppress bone turnover and can impair healing in the jaw. A thorough dental evaluation helps identify active infections, cavities, periodontal disease, or teeth that are likely to fail and may need extraction or other treatment before therapy begins. By addressing these issues beforehand, you reduce the chance of osteonecrosis of the jaw, a serious complication where the jawbone can die and fail to heal after dental procedures or trauma. This risk is especially pertinent with high-dose regimens used in cancer settings, and the effects can persist for years because the medication stays in bone. So, the dental clearance acts as a preventive step to protect jaw health during and after treatment. Checking blood sugar or evaluating tooth color doesn’t address this specific risk, and a dental evaluation is not unnecessary.
