Indices in dental image exams for bone mineral density evaluation of aromatase inhibitor users.

We evaluated the accuracy of radiomorphometric indices (RI) and fractal dimension (FD) for screening bone mineral density (BMD) in postmenopausal patients who had breast cancer and were using aromatase inhibitors (AI). The sample consisted of 40 participants. Digital panoramic radiography (DPR) and cone beam computed tomography (CBCT) were evaluated along with dual-energy X-ray absorptiometry (DXA), which is the gold standard for detecting low BMD.

Prevalence of primary osteoporosis and low bone mass in postmenopausal women and related risk factors.

Background: Globally, 30% of female over 50 years old have osteoporosis. This disease is one of the major causes of disability and death in the elderly. This research was aimed to determine the prevalence of primary osteoporosis and low bone density based on bone mineral density in postmenopausal women and its sociodemographic, obstetric, and life style risk factors.

Is the NHANES III femoral neck database discordant with the total hip and trochanteric region databases?

The results of dual-energy X-ray absorptiometry (DXA) testing frequently leads to a significant clinical treatment decision, based on T-score or Z-score results. Using the nearly universally accepted World Health Organization (WHO) criteria, which in turn are based on the validity of the population database, a flawed database may lead to an incorrect and deleterious clinical categorization. We have observed that the Hologic National Health and Nutrition Examination Survey III (NHANES III) femoral neck scores are frequently disproportionately low compared with scores in the other major hip regions and that the discordance is statistically significant.
