background: the aim of the present study was to evaluate the relationship between the bone density of various regions of jaws and skeletal bones. materials and methods: a total of 110 patients with a mean age of 55.01 ± 10.77 years were selected for the purpose of the present descriptive study. dual x-ray energy absorptiometry (dxa) was carried out to determine bone mineral density (bmd) of the...

INTRODUCTION Osteoporosis and tooth loss have been linked with advancing age, but no clear relationship between these conditions has been proven. Several studies of bone mineral density measurements of the jaw and spine have shown similarities in their rate of age-related deterioration. Thus, measurements of jawbone density may predict lumbar vertebral bone density. Using jawbone density as a p...

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 all-...

BACKGROUND Determining bone mineral density (BMD) with dual-energy x-ray absorptiometry (DXA) is an established and widely used method that is also applied prior to biomechanical testing. However, DXA is affected by a number of factors. In order to delay decompositional processes, human specimens for biomechanical studies are usually stored at about -20 degrees C; similarly, bone mineral densit...

UNLABELLED We provide the first reference values for bone mineral content and bone mineral density according to age and sex in Iranian children and adolescents. The prevalence of hypovitaminosis D was high, and levels of physical activity were low in our sample. Multiple regression analyses showed age, BMI, and Tanner stage to be the main indicators of bone mineral apparent density. PURPOSE N...

Background: Failure to maintain bone mass density is a major complication in patients with cystic fibrosis (CF). This study was conducted to evaluate the prevalence of low bone mineral density (BMD) and also identifying associated risk factors in CF patients. Materials and Methods: Present study conducted on 59 CF patients aged 5-35 years referred to respiratory clinic of Masih Daneshvari Hospi...

Background DTG is a once-daily integrase inhibitor that in combination with ABC/3TC, demonstrated superior efficacy with favorable tolerability over TDF/FTC/EFV (SINGLE study) at 48 weeks. EFV is associated with reduced Vitamin D levels through CYP450 enzyme induction; TDF has been associated with decreased bone mineral density (BMD). Antiretroviral treatment (ART) initiation is characterized b...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

OBJECTIVE Prolonged immobilization in stroke is known to result in hypercalciuria, hypercalcemia, accelerated bone resorption, and osteoporosis. Furthermore, bone mineral loss accelerated with increasing duration of hemiplegia. Although stroke is a common disease that causes sudden immobilization, relatively few investigations of bone metabolism in stroke have been reported. The aim of this stu...
