background and aims. a proper bond must be created between the existing composite resin and the new one for successful repair. the aim of this study was to compare the effect of three mechanical surface treatments, using diamond bur, air abrasion, and er,cr:ysgg laser, on the repair bond strength of the silorane-based composite resin. materials and methods. sixty cylindrical composite resin spe...
objective: to evaluate the feasibility and results of using serosal patch of small bowel for repair and replacement of inferior vena cava (ivc) after resection of a part of infra-renal ivc in an animal model, as it may be encountered in extensive tumors of retroperitoneal and trauma patients. methods: five healthy sheep of both sexes were prepared. after general anesthesia and laparotomy, a def...
hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (avr).the mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. it appears to be independent of its severity as assessed by echocardiography. we present a case of a 24-year-old man with a histo...
the aim of this study was to compare the effect of an acidic environment on dislocation resistance (push-out bond strength) of endosequence root repair material (errm putty and errm paste), a new bioceramic-based material, to that of mineral tri-oxide aggregate (mta).one-hundred twenty root dentin slices with standardized canal spaces were divided into 6 groups (n = 20 each) and filled with too...
