Objective: Studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. Thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. The conventionally used acrylic resin has a low coefficient of thermal conductivity. This study aimed to improve the thermal conductivity of acry...

introduction: biocompatibility and antimicrobial activity of endodontic materials are of utmost importance. considering the extensive applications of mineral trioxide aggregate (mta) in dentistry and antimicrobial properties of silver nanoparticles, this study aimed to evaluate the subcutaneous inflammatory reaction of rat connective tissues to white mta with and without nanosilver (ns) particl...

This study was carried out to assess the effect of clinoptilolite coated with silver nanoparticles on meat quality attributes of broiler chickens during frozen storage. A total of 375 one-day-old broiler chicks were assigned in a completely randomized design to 1 of 5 experimental groups including: basal diet, basal diet supplemented with 1% clinoptilolite and basal diet supplemented with 1% cl...

  Objective: Nanosilver has numerous applications in medicine due to its potent antibacterial activity. However, data regarding the bio-safety of its effective concentrations is scarce. This study aims to assess the toxicity of silver nanoparticles on human gingival epithelial cells under in-vitro conditions.   Methods: This in vitro study evaluated the toxic effects of filtered and unfiltered ...

conclusions based on the present study, it can be concluded that oral administration of silver nanoparticles for 28 days had no effect on rat liver function, but probably led to early apoptotic stages. materials and methods in this experimental study, 40 adult male sprague-dawley rats were divided into five groups. in the four experimental groups, nanosilver particles were given orally for 28 c...

To evaluate the effect of nanosilver (5, 10 and 20 mg l-1), hydrogen peroxide (200, 400 and 600 µM) and Nanosil (200, 400 and 600 µM) as antimicrobial compounds in vase solution of cut rose cv. ‘Grand Press Angela’ flowers, an experiment with 10 treatments and 3 replications was conducted in a completely randomized design. Cut rose flowers were continuously treated with these compounds. The res...

nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. the nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. some samples of breast muscle, femora muscle, heart, gizzard, liver, skin, spleen, lung, kidney and cloacal feces were collected randomly in slaughter...
