INTRODUCTION Enterococcus faecalis (E. faecalis) has the ability to invade the dentinal tubules and resist high pH levels. As a result, calcium hydroxide (CH) is not much effective on this bacterium. In theory, nanoparticle calcium hydroxide (NCH) has smaller size and high surface area that enables it to penetrate into the deeper layers of dentin and be more effective on E. faecalis. This in vi...

Treatment outcome of endodontic perforations depends on successful elimination of the associated microorganisms and infected tissues as well as the effective seal of the root-end or perforation site to prevent future contamination. Ideally, perforation repair material has to be bacteriostatic or bactericidal in order to prevent bacterial contamination as well as good sealing properties and bioc...

we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...

Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...

BACKGROUND AND OBJECTIVE Reports on MRSA strains are increasing worldwide. The aim of this study was to find the prevalence of MRSA strains isolated from clinical specimens and to evaluate their resistance profile. Additionally we compared the phenotypic and genotypic methods for detection of methicillin resistance. MATERIALS AND METHODS In this cross-sectional study, a total of 41 isolates o...

ABSTRACT: Pressure injury they are chronic wounds where the is bacterial infection common and represent a challenging problem for public health. The aim of this study was investigating antimicrobial activity Mangifera indica on bacteria associated by pressure injury. In vitro tests were conducted with crude extract fractions organics against strains Staphylococcus aureus (ATCC 25923), epidermid...

a study was performed to determine the species and antimicrobial susceptibility of 100 enterococcus strains from various clinical specimens as etiological agents at the clinical microbiology laboratory, istanbul university, medical faculty hospital. out of 100 enterococcal isolates, 86 were identified as e. faecalis, 11 as e. faecium, 1 as e. avium and 2 as e. raffinosus. by the disk diffusion ...
