Dental patients who have been alarmed or confused by recent news reports about how osteoporosis medications might affect their oral health now have a brochure to help them separate fact from fiction. The American Dental Association (ADA) collaborated with the National Osteoporosis Foundation to create the brochure, "Osteoporosis Medications and Your Dental Health," which will be available in dental offices this month.
The brochure explains that some patients who have taken bisphosphonates, a common class of drugs taken by those with osteoporosis or low-bone density, have developed bisphosphonate-associated osteonecrosis of the jaw. Osteonecrosis of the jaw is a rare but serious condition that can cause severe damage to the jawbone. This condition is diagnosed in patients who have an area of exposed bone in the jaw that persists for more than eight weeks, who have no history of radiation therapy to the head and neck and who are taking, or have taken, a bisphosphonate medication.
The chance of developing osteonecrosis of the jaw for patients who take bisphosphonates is unknown; however researchers agree that the chance appears to be very small. In fact, 94 percent of people diagnosed with osteonecrosis of the jaw are cancer patients who are or have received repeated high doses of bisphosphonates intravenously. The remaining 6 percent diagnosed with osteonecrosis of the jaw took oral bisphosphonates.
