conclusions abnormal dexa was highly prevalent among patients with cirrhosis. the risk of this finding was increased by lower vitamin d levels, advanced disease, and impaired renal function. objectives we aimed to investigate bone loss in patients with cirrhosis at different anatomical sites and key factors that might affect it. patients and methods in this cross-sectional study, 97 patients wi...
background: osteoporosis is a major public health concern around the world. it has been shown that bone mineral density is correlated to anthropometric measures like height and weight, but this association may vary depending on ethnic and environmental factors. the aim of this study was to identify probable relations between anthropometric measures and bone mineral density. methods: in this po...
osteoporosis is a silent epidemy of today's world, and is also a prevalent problem of health in iran. the role of nutrients such as ascorbic acid, a key antioxidant vitamin, in this disease has recently attracted researchers' attention. in this study, we studied the relation between plasma ascorbic acid concentration and bone mineral density (bmd) in women referring to jami clinic, te...
background: tea consumption is common in our country and consumes more than coffee and other drinks. many studies investigated the association between coffee and bone mass density (bmd) but there is few study about association between tea and bmd. according to high prevalence of osteoporosis in country and change in demographic patterns that is associated with increasing middle-aged and older a...
objective: to assess the stability changes as a reflection of early healing around roughened- surface implants in human by resonance frequency analysis (rfa). materials and methods: one hundred and fifty one iti sla implants were placed in either maxilla or mandible of 68 patients. bone type was classified into 4 groups according to lekholm and zarb index. rfa was used for direct implant stabil...
osteoporosis is a skeletal disease characterized by reduction in bone mass and micro architectural changes in the bone, which leads to increased bone fragility. the gold standard for the diagnosis of osteoporosis is the measurement of bone mineral density (bmd) by dual energy x-ray absorptiometry (dxa). periodontal disease is a chronic destructive disease which can occur in adults, young people...
context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...
Abstract Background: The aim of this study was to examine the effect of isometric training on prevention of bone density reduction of limbs during an immobilization period. Methods: In this quasi-experimental study, 60 men with fractures of the femoral bone, needing at least one month immobilization period, were selected and randomly assigned in control and experimental groups, the latter u...
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...
objective(s): the aim of this study was to observe the influence of phytoestrogen α-zearalanol on ovariectomy-induced postmenopausal osteoporosis in rats. materials and methods:40 sd female rats were randomly divided into four groups: sham group, ovx group (ovariectomized and fed estrogen), α-zearalanol group (ovariectomized and fed α-zearalanol) and untreated group (ovariectomized). three week...
