Dental X-rays could screen for osteoporosis: study

Dentists may be able to help screen women for osteoporosis by looking at X-rays that they are taking anyway, Japanese researchers reported on Tuesday.

Panoramic dental X-rays, which show the whole jaw, can also show the beginnings of low skeletal bone mineral density, they said. This is the first step towards osteoporosis.

Dr. Akira Taguchi of Hiroshima University Hospital and colleagues studied 316 postmenopausal women, without symptoms of osteoporosis, who had dental X-rays performed.

The X-rays were just as sensitive as questionnaires in identifying the women who were likely to have the beginnings of osteoporosis, Taguchi reported in the December issue of the American Journal of Roentgenology.

Women may be more likely to take a trip to the dentist’s office than to get checked for osteoporosis, Taguchi said.

“The response rate for questionnaires may be relatively low if post-menopausal women have little information or no interest regarding osteoporosis,” Taguchi said in a statement.

Women with a small frame, of Caucasian descent and who are poorly nourished have a higher risk of osteoporosis.

Worldwide, 30 to 40 percent of all women and one in five of all men will have osteoporosis in their lives, often severe enough to cause a bone fracture according to the International Osteoporosis Foundation.
