Past studies in humans have demonstrated horizontal and vertical bone loss after six months following tooth extraction. Many biomaterials have been developed to preserve bone volume after tooth extraction. Type I collagen serves as an excellent delivery system for growth factors and promotes angiogenesis. Calcium phosphate ceramics have also been investigated because their mineral chemistry res...

Body weight is positively associated with bone mineral density but the relationship between obesity and bone mineral density is unclear. Leptin and adiponectin are potential independent contributors to bone mineral density. We assessed the correlations of body composition, leptin and adiponectin with bone mineral density, and whether leptin, adiponectin and body composition determine bone miner...

Background: Total bone mass acquired during childhood is known to be the most important determinant and base of lifelong skeletal health. The present study investigated the prevalence of low bone mass for chronological age (LBM) in lumbar and femoral areas of leukemic children in the south of Iran and evaluated the association of anthropometric, clinical and laboratory data of these children ...

Background: The purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. Patients and Methods: This was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the ...

background: osteoporosis (op) is a common complication of inflammatory arthritis such as rheumatoid arthritis (ra). in this study we evaluated osteoporosis and its related factors in ra patients. methods: this cross - sectional study was carried out from 2010 to 2011 on 121 women with ra aged 45-75 years. these patients were selected and divided in two groups according to their bone mineral den...

background: low bone mass is a major health problem in postmenopausal women.there is no general agreement regarding relationship between serum level of lipidsand bone mineral density.objective: this study was carried out to investigate the association between lipidprofile and bone mineral density (bmd) in postmenopausal women in yazd, iran.materials and methods: this cross-sectional study was p...

background and aims. the aim of this study was to evaluate the sealing ability of kryptonite bone cement (doctors research group inc, southbury, ct, usa) in retrograde cavities by comparing with mineral trioxide aggregate (mta) (dentsply tulsa dental specialties, tulsa, ok, usa), amalgam and intermediate restorative material (irm) (dentsply caulk, milford, de, usa) using ultrasonic retrograde p...

bone disorders have emerged as a worrisome complication in hiv-infected patients in recent years. it is not clear that hiv infection itself or antiretroviral treatment or both are causes of bone loss. however, most studies have found a high prevalence of osteopenia and osteoporosis in hiv/aids patients. the objectives of this study were to determine the prevalence of osteopenia and osteoporosis...
