the biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (adscs) to repair peri-implan...

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: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection ne...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

background: to investigate the relationship between renal stone formation and osteoporosis. methods: eight hundred thirty healthy subjects aged between 20 and 76 years were randomly selected from 50 clusters to take part in the study. of these, 68 (8.2%) had a previous history of renal stone disease. all participants underwent clinical exami nation and bone mineral densitometry of the lumbar sp...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...
