OBJECTIVE The purpose of this study was to determine the antibacterial effect of a newly developed haemostatic agent Ankaferd Blood Stopper® (ABS) and Ferric Sulphate (FS) on various oral microorganisms. STUDY DESIGN Bacterial strains were freshly incubated in their specific broth media. For each of the strains, 3 wells per each agent, with a 5 mm diameter were made under aseptic conditions i...

BACKGROUND Catheter colonization and bloodstream infection during the first week after insertion of a central venous catheter have been shown to result from the patient's own skin flora. METHODS The backs of 32 healthy subjects were prepped with a 2% chlorhexidine gluconate (CHG)/70% isopropyl alcohol antiseptic. Three dressings, 2 of which contained CHG, were placed on the prepped skin in a ...

BACKGROUND Chlorhexidine has been widely used for hand hygiene to prevent transmission of nosocomial pathogens, including methicillin-resistant Staphylococcus aureus (MRSA). However, data on longitudinal surveillance of the susceptibility of MRSA isolates to chlorhexidine are limited. METHODS A total of 240 nosocomial MRSA isolates obtained in 1990, 1995, 2000 and 2005 at National Taiwan Univ...

OBJECTIVE To evaluate the effects of different concentrations of chlorhexidine on the decline in force of orthodontic elastics. MATERIALS AND METHODS In a laboratory study, five groups of samples were tested, with one control group represented by distilled water (group 1) and four experimental groups: 0.12% manipulated chlorhexidine (group 2), 0.2% manipulated chlorhexidine (group 3), 0.12% c...

Chlorhexidine, a bitter bis-biguanide antiseptic, is the only known blocker of the human salty taste. In order to characterize the effects of chlorhexidine on stimulus identification, taste confusion matrix (TCM) performance was measured for subjects treated with 1.34 mM chlorhexidine gluconate (n = 9) and water controls (n = 9). Ten stimuli [water, 0.1 M NaCl, 0.1 M KCl, 0.1 mM quinine-HCl (QH...

BACKGROUND Previous in vitro studies showed little bactericidal effect on structured oral biofilm after exposure to chlorhexidine (CHX). In vivo evidence of a CHX effect against structured biofilm is scarce. The purpose of this study was to compare the efficacy of 0.12% CHX gluconate on previously plaque-free and plaque-covered surfaces. METHODS This study had a single-masked, randomized spli...
