Osteoporosis affects almost 15% of Western women in their fifties, 22% in their sixties, and 38.5% in their seventies. As many as 70% of women over 80 are at risk, and the condition carries a high risk of bone fractures, with over a third of adult women falling victim at least once in their lifetime. Wide-scale screening for the disease is not currently viable, largely due to the cost and scarcity of specialist equipment and staff.
The team has therefore developed an innovative software-based approach to detecting osteoporosis using routine dental x-rays, by automatically analyzing specific characteristics of the radiographic trabecular bone pattern. These features include, among others, the thickness, the amount of fragmentation, and the main orientation of the structure of the trabecular bone.
In four clinical centers, 671 women with an average age of 55 years were recruited. To obtain the “gold standard? the team measured bone thickness at the femur, hip, and spine, using the technique that is common for this kind of expensive examination (Bone Mass Density, BMD). In addition, one panoramic and two intra-oral radiographs were made.
X-rays are used widely in dental practice for several reasons. Using the image information from these radiographs to detect patients at risk for osteoporosis involves no extra radiation and almost no extra cost, while undetected osteoporotic patients can incur bone fractures and suffer from other pr
