background: recently, tissue engineering has developed approaches for repair and restoration of damaged skeletal system based on different scaffolds and cells. this study evaluated the ability of differentiated osteoblasts from adipose‑derived stem cells (adscs) seeded into hydroxyapatite/ tricalcium phosphate (ha‑tcp) to repair bone. methods: in this study, adscs of 6 canines were seeded in ha...

background. repairing aged composite resin is a challenging process. many surface treatment options have been proposed to this end. this study evaluated the effect of different surface treatments on the shear bond strength (sbs) of nanofilled composite resin repairs. methods. seventy-five cylindrical specimens of a filtek z350xt composite resin were fabricated and stored in 37°c distilled water...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

background: peritendinous adhesions after repairing an injury to the digital flexor tendons are a major problem in hand surgery. non-steroidal anti-inflammatory drug therapy may affect tendon healing and the development of peritendinous adhesions. the aim of this study was to evaluate ibuprofen effect in patients function after flexor tendon surgical repair.   method: thirty-five patients, who ...

introduction: the purpose of this study was to compare the push-out bond strength of white proroot mineral trioxide aggregate (mta), biodentine, calcium-enriched mixture (cem) cement and endosequence root repair material (errm) putty after exposure to blood. methods and materials: a total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...
