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 This prospective study was conducted to demonstrate the role of bone mineral density (BMD) and bone scan in the management of adult Saudi female patients with established diagnosis of osteomalacia. METHODS Bone scan using Tc99m methylene diphosphonate (MDP) and BMD of the lumbar spine and femoral neck using dual x-ray absorptiometry (DXA) were performed at the time of diagnosis 6 mo...
OBJECTIVE The objective of this study was to investigate the effect of mechanical strain by mapping physicochemical properties at periodontal ligament (PDL)-bone and PDL-cementum attachment sites and within the tissues per se. DESIGN Accentuated mechanical strain was induced by applying a unidirectional force of 0.06N for 14 days on molars in a rat model. The associated changes in functional ...
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 ...
Bone substitutes are nowadays largely used in orthopedic surgery but they lack osteoinductive properties. Poly (2-hydroxyethyl methacrylate) (pHEMA) has numerous biomedical applications. Alkaline phosphatase (AlkP), an ectoenzyme elaborated by osteoblasts, initiates bone mineralization by hydrolyzing organic phosphates before calcium-phosphorus deposition. We have immobilized AlkP in pHEMA in a...
Mortality in swine herds is often associated with lameness, and trace minerals are implicated in maintaining integrity of skeletal tissues. The objectives of this study were to determine if prolifi c sows displayed evidence of trace mineral depletion with age and to determine the prevalence of osteochondrosis (OC) lesions. Reduced mineral concentrations with age would support recommendations fo...
