Objective: Leukocyte adhesion deficiency(LAD) is a scarce, autosomal recessive inherited disorder . LAD-I which is the most common type occurs due to mutations on the CD18 gene. This mutation leads to absence or severe reduction of leukocyte cell surface expression of ß2 integrin molecules which are necessary for the adhesion of the leukocytes to the endothelial cells, transendothelial mi...

Background and ObjectiveRadiographic examination has an important role in diagnosis and treatment of periodontal patients, so this study was performed to determine the accuracy of digital bite wing (CMOS) radiography in alveolar bone resorption. Materials and Methods: This cross-sectional study was performed on 61 teeth of 16 periodontal patients referred to the periodontoloy department of R...

PURPOSE To compare diameter-based glenoid bone loss quantification with a true geometric calculation for the area of a circular segment. METHODS By use of Maxima 12.01.0 mathematics modeling software (Macysma, Boston, MA), the diameter-based glenoid bone loss equation (% Bone loss = [Defect width (w)/Inferior glenoid circle diameter (D)] × 100%) was compared with a true geometric calculation ...

The elderly are more likely to suffer from fracture because of age-related trabecular bone loss. Different bone loss locations and patterns have different effects on bone mechanical properties. Extended finite element method (XFEM) can simulate fracture process and was suited to investigate the effects of bone loss on trabecular bone. Age-related bone loss is indicated by trabecular thinning an...

Periodontitis and other bone loss diseases, decreasing bone volume and strength, have a significant impact on millions of people with the risk of tooth loss and bone fracture. The integrity and strength of bone are maintained through the balance between bone resorption and bone formation by osteoclasts and osteoblasts, respectively, so the loss of bone results from the disruption of such balanc...

PURPOSE This retrospective study evaluated the relationship between the timing of peri-implantitis diagnosis and marginal bone level after a 5-year follow-up of non-surgical peri-implantitis treatment. METHODS Thirty-three patients (69 implants) were given peri-implantitis diagnosis in 2008-2009 in Seoul National University Bundang Hospital. Among them, 31 implants from 16 patients were inclu...

Purpose: Given that physical activity is the most important environmental moderating factor, it has been known as an effective, available, low-cost and non-pharmacological approach to increase or maintain bone density at different ages. The purpose of this study was to investigate the effect of 12 weeks of training in water, on land and combined environment on bone mineral density in premenopau...
