background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

conclusions the outside diameter/inside diameter ratio at the metaphyseal/diaphyseal junction of the distal radius on ap radiographs is suitable for use as a predictor of distal-radius bone density. further studies should be performed, and clinical utility evaluated. results the mean bmd was 0.559 (sd = 0.236) g / cm2. the mean outside diameter/inside diameter ratio was 1.24 (sd = 0.013); the r...

Introduction: In this study, we intend to determine the correlation between the thickness of the cerebral cortex and the severity of the cognitive disorder in Alzheimer disease (AD). Methods: A total of 20 (14 women and 6 men) patients diagnosed with AD with a Mean age of 72.95 years, and 10 (7 women and 3 men) cognitively normal (CN) subjects with a Mean age of 70.50 years were included in th...

objective: implants are being used in orthodontics as a reliable mode of anchorage. among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. the objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. th...

Neuroimaging research indicates that human intellectual ability is associated to brain structure including the thickness of the cerebral cortex. Most studies show that general intelligence is positively associated with cortical thickness in areas of association cortex allocated throughout both brain hemispheres. Changes in cortical thickness over time have been related to intelligence, but whet...

Purpose: In this study, the main goal was to determine the correlation between the thickness of cerebral cortex and the severity of cognitive disorder in Alzheimer's disease Materials and method: Twenty patients diagnosed with Alzheimer’s disease with mean age of 72.95 year(14 women and 6 men) and Ten Cognitively normal (CN) subjects with mean age of 70.50 year( 7 women and 3 men) were include...

this study was aimed to investigate the use of panoramic radiography in patients with low bone mineral density (bmd) in order to diagnose and prevent osteoporotic fractures. panoramic radiographs of 60 patients  (20 men and 40 women) aged from 40 to 70 years with cortical thicknesses of less than 3 mm in the mandibular angle were selected from patients referred to a dentomaxillofacial radiology...
