Background: A better understanding of how bone mineral density and vitamin D levels are associated with femoralneck and intertrochanteric hip fractures may help inform healthcare providers. We asked: 1) In patients age ≥ 55 years,is there a difference in quantitative ultrasound of the heel (QUS) t-score between patients with fractures of the femoralneck and those with fractures of the intertroc...

background: plasma rich in growth factors (prgf) and freeze‑dried bone allograft (fdba) are shown to promote bone healing. this study was aimed to histologically and histomorphometrically investigate the effect of combined use of prgf and fdba on bone formation, and compare it to fdba alone and control group. materials and methods: the distal roots of the lower premolars were extracted bilatera...

objective: to determine the prevalence of fractures and associated risk factors in healthy iranian children and adolescents. methods: in this cross sectional population based study, 478 healthy iranian children and adolescents aged 9–18 years old participated. baseline data and bone mineral content and density have been determined. one questionnaire was completed for all individuals including p...

introduction: thalassemia is the most common genetic disorder, affecting around 200 million people worldwide. the etiology of this bone disease is multifactorial. seemingly, in the setting of increased bone turnover which manifests by increased bone resorption and remodeling; bone density decreases. in this research, thalassaemia patients with osteoporosis were placed on oral alendronate therap...

Introduction: The aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (BMD) in male rats. Materials and methods: In this experimental study, 24 Wistar male rats, aged between 15 and 20 days, were selected. The rats were randomly divided into 3 groups: immune system supplement (ISS), ...

statement of problem: the goal of bone regenerative therapy is to reconstruct the damaged tissues to initial condition, which seems so important in periodontoiogy and implantology. in such therapies, different biomaterials, with some advantages and disadvantages, may by use.purpose: the aim of this research was to evaluate the quality, bone trabecular density and thickness of newly forming bone...
