Data from healthy children are needed to evaluate bone mineralisation during childhood. Whole body bone mineral content (BMC) and bone area were examined by dual energy x ray absorptiometry (Hologic 1000/W) in healthy girls (n = 201) and boys (n = 142) aged 5-19 years. Centile curves for bone area for age, BMC for age, bone area for height, and BMC for bone area were constructed using the LMS m...

Initiated and motivated by clinical and scientific problems such as age-related bone fracture, prosthetic loosening, bone remodeling, and degenerative bone diseases, much significant research on the properties of trabecular bone has been carried out over the last two decades. This work has mainly focused on the central vertebral trabecular bone, while little is known about age-related changes i...

Physical exercise enhances bone acquisition during adolescence. The aim of the study was to evaluate the influence of intensive physical exercise on bone acquisition in adolescent elite artistic gymnasts. The study included 262 athletes (93 males and 169 females, aged 13-23 yr) participating in the 24th European Championship held in Greece. Bone age compared with chronological age was delayed b...

Background: Expansion of bone marrow cavity and decreased cortical and trabecular bone tissues and osteoporosis are resulted from beta-thalassemia. The aim of this study was to assess bone mineral density (BMD) in patients with β thalassemia major and intermedia, and to determine their biochemical and hormonal profiles that may affect BMD. Materials and Methods: In a cross sectional study from ...

Objective: To establish whether type 1 diabetes mellitus (T1DM) has a long-term effect on bone development in children and adolescents. Methods: Bone characteristics and muscle cross-sectional area (CSA) were analyzed crosssectionally at study start in 41 (19f/22m) patients and reevaluated after 5.56 ± 0.4 years using peripheral quantitative computed tomography (pQCT). We hypothesize that bone ...

This study was undertaken to assess the frequency of decreased bone mineral density and its risk factors as well as its impact on the quality of life during childhood among hemophiliac patients. Materials and Methods: Thirty seven children with severe hemophilia A and B, referred to Mofid Children’s Hospital during 2010, were selected. For all patients the joint score, body mass indexes, bone...

Bone age assessment is a task performed daily in hospitals worldwide. This involves a clinician estimating the age of a patient from a radiograph of the non-dominant hand. Our approach to automated bone age assessment is to modularise the algorithm into the following three stages: segment and verify hand outline; segment and verify bones; use the bone outlines to construct models of age. In thi...

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...

background: fracture, is discontinuity of anatomical bone relations. commonly, a maxillofacial fracture occurs after trauma but the etiology and pattern of this entity is different amongst countries. the aim of this study was to clarify the main causes of this entity in yazd to increase public and professional awareness to prevent more injuries and subsequent consequences. materials and methods...

Introduction: Treatment of edentulous atrophic mandible with severe atrophy is a challenge based on local conditions and systemic diseases confronted by the age group affected. If bone grafting is indicated, it is often used in lateral or inferior aspects of the mandible.  Case Report: A 70-year-old male with a unilateral fracture of the atrophied left mandibular body was managed by lingual bon...
