Medical clay also known as medicinal was first used in Mesopotamia around 2500 B.C and is still a relevant topic today. Among typical medical clays, sepiolite, fibrous the family of palygorskite often ignored by cosmetic brands it not found abundantly nature much other clays like bentonite. However, world reserves this are Turkey. In study, antibacterial sepiolite prepared from nanosilver added...

INTRODUCTION Favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. The aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods. MATERIALS AND METHODS Fift...

STATEMENT OF THE PROBLEM Nanosilver particles have the potential to serve as a bactericidal agent because of the inherent antimicrobial influences of silver ion. The literature confirmed that specific micro-organisms, especially streptococci, have an important role as an etiological factor for caries. PURPOSE The aim of this study was to evaluate the antimicrobial effect of conventional and n...

Nanosilver particles are used in various clinical settings because of their antibacterial properties. However, their safety evaluation when used for gynaecological disorders has not been established. Nanosilver particles were administrated in the vagina of New Zealand rabbits, and the pathological appearance of the surrounding tissue was examined by hematoxylin-eosin staining and transmission e...

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...

As a result of growing applications of manufactured nanoparticles, there is an increasing concern aboutpossible side effects of exposure to these materials on human and environment. Nanosilver (n-Ag) has foundwide use in medical applications including development of silver-based dressings and silver-coated medicaldevices. However, toxicity of these particles clue to their dermal use has not bee...

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...

Silver nanoparticles (Ag NPs) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. Present study compares the tissue levels of Ag NPs in different organs of Guiana Pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the Ag NPs tissue levels. Before toxicological assessments,the...

OBJECTIVES Residual microorganisms in the root canal system (RCS) after endodontic therapy such as Candida albicans are a major cause of endodontic failure. Calcium hydroxide (CH) and chlorhexidine (CHX) have suitable antimicrobial activity against bacteria and can be used as intracanal medicaments. Nanosilver has also shown antimicrobial activity against microorganisms. This study aimed to com...

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...
