BACKGROUND The present study compared both the antiseptic efficacy of sodium hypochlorite against that of chlorhexidine gluconate in isopropyl alcohol and the substantive effect of chlorhexidine, povidone iodine, and sodium hypochlorite. METHODS This was a 2-step study that included volunteers. In step 1, 4 skin areas were tested for bacteria in colony-forming units (CFU): 2 were controls to ...

Objective: To compare the effectiveness of 2.5% sodium hypochlorite and 2% chlorhexidine, in reduction frequency pain 24 hours after endodontic treatment teeth with chronic apical periodontitis Study design Setting: Randomized Clinical Trial conducted –removed for blind review--from July 2018 to December 2018. Methodology: A total 60 patients requiring management pulp necrosis were randomly all...

BACKGROUND Effective neutralization in testing hand hygiene preparations is considered to be a crucial element to ensure validity of the test results, especially with the difficulty to neutralize chlorhexidine gluconate. Aim of the study was to measure the effect of chemical neutralization under practical test conditions according to EN 1500. METHODS We have investigated two ethanol-based han...

OBJECTIVES The aim of this study was to determine the effect of exposure to sublethal concentrations of chlorhexidine on oxidative stress protection by Acinetobacter baylyi ADP1. METHODS ADP1 cultures were exposed to sublethal concentrations of chlorhexidine prior to being challenged with lethal concentrations of chlorhexidine itself and by oxidants. Oxidant-sensitive dyes and a flow cytomete...

The aim of this study was to investigate in vitro the antimicrobial activity of 0.2%, 1%, and 2% chlorhexidine gluconate (CHX gel and CHX liquid), against endodontic pathogens and compare the results with the ones achieved by 0.5%, 1%, 2.5%, 4%, and 5.25% sodium hypochlorite (NaOCl). A broth dilution test was performed, and the timing for irrigants to kill microbial cells was recorded and stati...

introduction: the purpose of this study was to determine the in vitro antimicrobial ability against entrococcus (e.) faecalis of triple antibiotic paste and its components compared with calcium hydroxide mixtures . materials and methods: an agar well diffusion assay and mic method were used to determine the efficacy of the experimental medicaments in removing e. faecalis. medicaments were divid...

OBJECTIVE To determine the effectiveness of oral decontamination with 2% chlorhexidine solution for the prevention of ventilator-associated pneumonia (VAP). DESIGN Randomized controlled trial and meta-analysis. SETTING A tertiary care university hospital in Bangkok, Thailand. PARTICIPANTS Adult patients who received mechanical ventilation and who were hospitalized in intensive care units ...

background: addition of disinfectant to irreversible hydrocolloid impression materials can eliminate the disinfection step to avoid dimensional changes associated with it. the aim of the present study was to evaluate the effect of various disinfectant mixing liquids on the properties of commercially available irreversible hydrocolloid impression materials. materials and methods: four commercial...

The purpose of this investigation was to examine the in vitro susceptibility of Candida albicans to a mixture of chlorhexidine and calcium hydroxide using a tube dilution test. A suspension containing C. albicans was exposed to 2% chlorhexidine solution, calcium hydroxide paste and 2% chlorhexidine mixed with calcium hydroxide in plastic tissue culture wells. The tested agents were incubated wi...

PURPOSE To evaluate the MMP-inhibitory effect of chlorhexidine when incorporated in the primer of a two-step selfetching adhesive (Clearfil SE Bond). MATERIALS AND METHODS Powdered dentin made from human teeth was treated with Clearfil SE Bond primers containing chlorhexidine of different concentrations for 20 s or for 2 min. The collagenolytic activity of the dentin powder was assayed using ...
