objective: to assess the stability changes as a reflection of early healing around roughened- surface implants in human by resonance frequency analysis (rfa). materials and methods: one hundred and fifty one iti sla implants were placed in either maxilla or mandible of 68 patients. bone type was classified into 4 groups according to lekholm and zarb index. rfa was used for direct implant stabil...

osteoporosis is a skeletal disease characterized by reduction in bone mass and micro architectural changes in the bone, which leads to increased bone fragility. the gold standard for the diagnosis of osteoporosis is the measurement of bone mineral density (bmd) by dual energy x-ray absorptiometry (dxa). periodontal disease is a chronic destructive disease which can occur in adults, young people...

different opinions exit in histological typing of bone cysts. epidermoid cysts are very rare as the small numbers of published cases indicate. they arises following preceding trauma exclusively in distal phalanges and skull. the roentgenogram shows a round osteolytic resion with no trabecular pattern. we observed 2 cases of epidermoid cyst of finger in imam khomeini hospital central path depart...

objective: to determine the prevalence of fractures and associated risk factors in healthy iranian children and adolescents. methods: in this cross sectional population based study, 478 healthy iranian children and adolescents aged 9–18 years old participated. baseline data and bone mineral content and density have been determined. one questionnaire was completed for all individuals including p...

aneurysmal bone cyst (abc) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. treatment methods include surgical excision and curettage with or without bone grafting. we report a proximal femu...

although some vitamins have been shown to prevent glucocorticoids induced osteoporosis in short time, the magnitude of this effect remains to be clarified. the aim of this study was to evaluate protective effect of vitamin d3 on methylprednisolone acetate (mpa) induced osteoporosis in rats. twenty-four male sprague dawley rats were randomly divided into four groups: group a (n = 6), was a base ...

the purpose of the present study was to examine the effect of 3-years of moderate multi-component exercise training on bone mineral density and bone mineral content in a female subject with osteoporosis. a 57-year-old postmenopausal woman, a known case of osteoporosis following an accident, participated in this study. bone mineral density and bone mineral content was measured in the femoral nec...

abstract malacoplakia is a rare chronic inflammatory disease associated with infection and immunosuppression, and very few occurrences have been reported in the bone. the authors describe the case of a 22-year-old woman with paraplegia and urinary and fecal incontinence whose thoracic spine magnetic resonance imaging suggested a tumoral or extensive inflammatory process in the body of the 8th, ...

this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).
