Osteoporosis risk group: Screening for osteoporosis in dental clinics using panoramic radiographs.

Osteoporosis is a specific condition which is characterized by low bone mineral density (BMD) and deterioration of bone structure resulting in an increased susceptibility to fractures. It contributes to a great deal of morbidity and mortality, and is a large burden to the healthcare system, especially in the case of the elderly population. In the last four decades, a plethora of studies have reported characteristic oral radiographic findings in the early stages of osteoporosis, suggesting the possible use of oral radiographic signs for the early detection of the condition. Digital orthopantomographs (OPGs) are usually taken for the screening of dental patients during routine dental evaluations. These radiographs and the characteristic changes seen on them may have a significant role in the screening for initial osteoporotic changes. A number of precise radiomorphometric indices of the mandible have also been developed to allow quantification of the mandibular bone mass for identification of the initial signs of osteoporosis. The present review focuses on the possible role of panoramic radiographs in the initial screening for osteoporosis in dental clinics in high-risk groups.
