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...

OBJECTIVE To investigate the relationship between total and segmental body fat, bone mineral density and bone mineral content in undergraduate students stratified according to nutritional status. METHODS The study included 45 male undergraduate students aged between 20 and 30 years. Total and segmental body composition, bone mineral density and bone mineral content assessments were performed ...

BACKGROUND Preoperative periarticular bone quality is affected by joint loading. The purpose of this study was to determine the periarticular bone mineral density of the knee joint of patients undergoing total knee arthroplasty, and whether the location of the load-bearing axis correlates with the measured bone mineral density. MATERIALS AND METHODS The bone mineral densities of the medial an...

The purpose of this study was to examine associations among bone mineral density, osteopenia/osteoporosis, body mass index (BMI), and body composition in patients with heart failure (HF). A total of 119 patients (age = 61 ± 12 years, 65% male) underwent dual-energy X-ray absorptiometry scans to determine bone mineral density and body composition. In multivariable linear regressions, BMI, relati...

statement of problem: reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. platelet-rich plasma (prp) offers a new and potentially useful adjunct to bone substitute materials (e.g. xenografts) in oral and maxillofacial bone and implant reconstructive surgery. purpose: an animal study was carried out to investigate the influence of prp ...

BACKGROUND Recombinant human bone morphogenic protein-2 stimulates bone augmentation in animal models. The aim of this study was to evaluate the capacity of bovine bone mineral coated with synthetic oligopeptides to enhance guided bone regeneration in the beagle 3-wall defect model and the clinical implications. METHODS The second and fourth mandibular premolars of four adult beagle dogs were...
