Calcium hydroxide had been used as the intra-canal dressing in endodontic treatment due to its high alkaline and antimicrobial capacity. It can also dissolve the necrotic tissue, prevent dental root resorbtion and regenerate a new hard tissue. The aim of this study was to determine the concentration of calcium hydroxide which had the highest antimicrobial effect on Streptococcus viridans. Sampl...

Antimicrobial resistance (AMR) is a global threat to public and animal health. The Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS), created in 2002, is a national program dedicated to the collection, integration, analysis, and communication of trends in antimicrobial use (AMU) and resistance (AMR) in selected bacteria from humans, animals, and animal-derived food ...

Virgin coconut oil is defined as the oil obtained from fresh coconut meat, without undergoing any chemical processes. Virgin coconut oil is mainly sold on the basis of its antimicrobial activity which is contributed to by its lauric acid. This study aimed to investigate the antimicrobial activity of commercial virgin coconut oil. Agar well diffusion test and disc diffusion test were first done ...

563 August 2014, Vol. 104, No. 8 The increasing prevalence of serious hospitaland community-acquired infections is of great concern, with patients dying as a result of emerging antimicrobial resistance. Antibiotic-resistant organisms are widespread globally, both in developed and developing countries.[1] These organisms are a major threat to public health, reduce the effectiveness of empiric an...

The Epsilometer test (E test; AB Biodisk, Solna, Sweden), a new quantitative technique for the determination of antimicrobial susceptibility, was compared to reference methods (agar dilution and broth microdilution) for the antimicrobial susceptibility testing of Helicobacter pylori. Seventy-one H. pylori strains isolated from patients with duodenal ulcers were tested against 20 antimicrobial a...

Silver has been used in medicine for centuries because of its antimicrobial properties. More recently, silver nanoparticles have been synthesized and incorporated into several biomaterials, since their small size provides great antimicrobial effect, at low filler level. Hence, these nanoparticles have been applied in dentistry, in order to prevent or reduce biofilm formation over dental materia...

Major advances in the development and use of antimicrobial textiles to control bacterial proliferation on wound beds continue. However, wound dressings are, in general, not included in standardized regimens for measuring and monitoring their antimicrobial effectiveness. This work adapts these methods to assess the antibacterial activity of textiles designed for wound healing purposes. Environme...

Polyacrylate and guanidine-based nanoparticles which involve acrylate monomers and glycidyl methacrylate modified oligo-guanidine were prepared by a seeded semi-continuous emulsion polymerization. The results from transmission electron microscope and dynamic light scattering measurements showed that the nanoparticles were spherical in shape and the particle size was in the range of 80–130 nm. A...

INTRODUCTION Surgical site infection remains a challenge for hospital infection control, especially when it relates to skin antisepsis in the surgical site. OBJECTIVE To analyze the antimicrobial activity in vivo of an antiseptic from ethanol crude extracts of P. granatum and E. uniflora against Gram-positive and Gram-negative bacteria. METHODS Agar drilling and minimal inhibitory tests wer...

BACKGROUND Clinical guidelines support a noninvasive Helicobacter pylori "test-and-treat" strategy for individuals with uncomplicated dyspepsia. However, consensus is lacking regarding the preferred noninvasive testing method. OBJECTIVE To use decision analytic modeling to estimate the clinical and economic outcomes associated with noninvasive tests designed to detect either H pylori antibody...
