BACKGROUND Various materials have been added to mineral trioxide aggregate to enhance its properties. This study was aimed to compare the sealing efficacy of MTA with and without nanosilver using bacterial leakage approach. MATERIAL AND METHODS Seventy canine teeth were prepared and obturated. Then, after apical resection, the root-end cavities were prepared by ultrasonic retrotips. Teeth wer...

Sintering of nanosilver paste has been extensively studied as a lead-free die-attach solution for bonding semiconductor power chips, such as the power insulated gated bipolar transistor (IGBT). However, for the traditional method of bonding IGBT chips, an external pressure of a few MPa is reported necessary for the sintering time of ~1 h. In order to shorten the processing duration time, we dev...

Silver ion has been used for centuries to prevent and treat a variety of diseases and infections. In recent years, extensive studies have been undertaken on the use of antimicrobial properties of silver, incorporated within medical devices. The aim of this study was to prepare a formulation containing silver ion, which could be applied for wound dressing. The purity of nanosilver was measured b...

Silver and gold have been used for centuries as antimicrobial agents. The aim of the study was to investigate diametral tensile strength, microhardness, ion release and light transmission of experimental resin composites. Flowable dental composite SDR (Dentsply, United Kingdom) was modified by nanogold, nanosilver and silica addition. The metal ion release, light transmission study, microhardne...

The aim of the present study was to elucidate the biological effectiveness and character of a nanosilver-epidermal growth factor (EGF) sustained-release carrier. This was synthesized using the self-assembly method and then characterized by transmission electron microscopy and UV spectrophotometry. The biological activity of the sustained release carrier was determined through cytological, bacte...

AIM The aim was to evaluate the antibacterial properties of composite resin containing nanosilver against Streptococcus mutans (SM) and Lactobacillus (L). MATERIALS AND METHODS Nanosilver was added to Z250 composite at 0.5 and 1% by weight. In order to confirm the homogenous distribution of the nanoparticles in the composite resin, SEM-EDX analysis was performed on one sample in each group. Z...

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...

objective(s): with the advent of nanotechnology, significant progress has been made in the area of nanoscale materials such as nanosilver (ag-nps). these nanoparticles have a wide range of applications and been used for antimicrobial purposes for more than a century. however, little attention has been paid to the toxicity of nanosilver wound dressing. this study was designed to investigate the ...

Silver has long been known to have antimicrobial properties and were used until chemical antibiotics came into vogue. Metallic silver and most inorganic silver compounds ionize in moisture, body fluids and secretions to release biologically active Ag+, which the silver ions have been used for the characteristics of toxicology and pharmacology as antimicrobial agent.1 Nanosilver particles have b...
