background radiography is as a part of periodontal examination. early detection of periodontal disease is important in the prevention of tooth loss and patient’s general health. objectives the objective of this study was to compare diagnostic accuracy of cone-beam computed tomography (cbct) with digital direct intraoral radiography, in assessment of periodontal osseous lesions. materials and me...

different studies have reported contradictory results about the effect of osteoporosis on periodontal status. we performed this study to evaluate the periodontal status of menopausal women by methods with enough accuracy and confidence.this study was performed based on the evaluation of bone mineral density using dual energy x-ray absorptiometry in 2010. a total of 60 patients who met the inclu...

objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

Periodontal bone loss results from bacterial infection and the associated host response. The ligand for the receptor activator of NF-κB (RANKL) induces the differentiation of osteoclasts, resulting in periodontal bone loss. The role of osteocytes in periodontal bone loss was investigated in this study. Transgenic mice expressing RANKL under the control of dentin matrix protein 1 (DMP1) were inf...

An association between bone disease and bone lead has been reported. Studies have suggested that lead stored in bone may adversely affect bone mineral metabolism and blood lead (PbB) levels. However, the relationship between PbB levels and bone loss attributed to periodontal disease has never been reported. In this study we examined the relationship between clinical parameters that characterize...

background: bone loss is one of the hallmarks of periodontitis. hence, a major focus of research into periodontal regeneration has concentrated on the initiation of osteogenesis. osteoinduction requires the differentiation of mesenchymal cells into osteoblasts with subsequent formation of new bone. the present study has been carried out to evaluate periodontal bone regeneration in intrabony def...

BACKGROUND Traditional methods of regenerating bone in periodontal bone defects have been partially successful and have involved numerous protocols and materials. More recently, it has been proposed that Er,Cr:YSGG laser energy may also be beneficial in the treatment of periodontal pockets, particularly in the regeneration of bone lost due to periodontal disease. CASE DESCRIPTION The purpose ...
