Dental x-rays could be first step in osteoporosis screening

01.12.2004


Panoramic dental x-rays can be used to help identify postmenopausal women with low skeletal bone mineral density (BMD), meaning that screening for spinal osteoporosis could begin in the dentist’s office a new study shows.



The study included 316 postmenopausal women who had no symptoms of osteoporosis. The women were divided into two groups: 159 had no history of hysterectomy, oophorectomy or estrogen use, the remaining 157 had one or more of these histories. All had panoramic dental x-rays, and the cortical shape and width of the jaw were estimated on the x-rays. "Women with eroded cortical shape need to be referred for further BMD testing," said Akira Taguchi, DDS, PhD, department of oral and maxillofacial radiology at Hiroshima University Hospital in Japan.

Currently, questionnaires are widely used as the first step in determining which women need to have further BMD testing. This study found that dental x-rays were just as sensitive as questionnaires in identifying those women. Dental x-rays, looking at cortical shape, were 87% sensitive in identifying women with spinal osteoporosis in the group with no history of hysterectomy, oophorectomy or estrogen use and 80% sensitive for the other group. The questionnaire was found to have an 87% sensitivity rate for the women with no history and 72% for those with the history of hysterectomy, oophorectomy or estrogen use, Dr. Taguchi said.


Dr. Taguchi noted that dental x-rays are not as specific as questionnaires, meaning that dental x-rays indicate disease when there isn’t any and can indicate there isn’t any disease and there is. However, since dental x-rays are already being done (about 15 million a year in the U.S.) they can be reviewed just as a first step in determining which women need additional testing, he said.

"The response rate for questionnaires may be relatively low if postmenopausal women have little information or no interest regarding osteoporosis," Dr. Taguchi said. On the other hand, "because dental panoramic x-rays are taken for the diagnosis of conditions affecting the teeth and jaws in clinical practice worldwide, the dentist could also look at the mandibular cortical shape and width and refer the appropriate women for further BMD testing," he said.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
