Silver nanoparticles (NPs) have at least one dimension of a particle smaller than 100 nm and contain 20-15,000 silver atoms. Due to its antibacterial activity nanosilver (NS) is used for medical purposes. NS particles can be obtained by various methods. Potentially, the best method of the NS synthesis for medical purposes is based on a brief flow of electric current between two silver electrode...

Modern titanium dioxide nanomaterials, in particular modified with nanosilver, have antiviral, antibacterial, antifungal activity, cytotoxic effects vitro experiments and can affect germ cells of warm-blooded laboratory animals. The research aims to study the effect different types nanoparticles on physiological biochemical characteristics wild boar vitro. When applying maximum dose (LD50) stud...

polymethyl methacrylate (pmma), widely used as a prosthodontic base, has many disadvantages, including a high thermal expansion coefficient and low thermal conductivity, a low elasticity coefficient, low impact strength and low resistance to fatigue. this study aimed to make an in vitro comparison of the thermal conductivity, compressive strength, and tensile strength of the acrylic base of com...

  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 ...
