AIM This study investigated the effectiveness of disinfecting solution when incorporated into alginate powder instead of water against some microorganisms and on compressive strength of alginate. MATERIALS AND METHODS For measuring antimicrobial activity of alginate, 60 alginate specimens were prepared and divided into two groups: One with water incorporated in the mix (control) and the other...

The aim of this study was to evaluate the effect of cariogenic challenge on the microtensile bond strength values (μTBS) of dentin pre-treated with chlorhexidine digluconate (CHX) or sodium hypochlorite (NaOCl). Thirty-six sound molars were selected and randomly assigned to 3 dentin pre-treatments (distilled water - control, 2% CHX and 10% NaOCl) and 4 aging protocols (24h control, biofilm with...

The purpose of this study was to compare the antimicrobial activities of 6% and 3% sodium hypochlorite (NaOCl), 2% and 0.12% chlorhexidine gluconate (CHX), and 0.01% and 0.005% doxycycline (Doxy) on four microorganisms associated with primary endodontic infections. The agar diffusion test was used to measure antimicrobial activities of these agents against Peptostreptococcus micros, Prevotella ...

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 Bacterial colonization of catheter tips is common in regional anesthesia and is a suspected risk factor for infectious complications. This is the first study evaluating the effect of CHG-impregnated dressings on bacterial colonization of regional anesthesia catheters in a routine clinical setting. METHODS In this prospective study, regional anesthesia catheter infection rates wer...

A new waterless surgical hand preparation containing 1% chlorhexidine gluconate (CHG) and 61% ethyl alcohol was evaluated for antimicrobial efficacy in comparison with a standard 4% CHG surgical scrub and a 61% ethyl alcohol control. Clinical studies were based on the Tentative Final Monograph for Health-Care Antiseptic Drug Products (TFM) (proposed rule) and the Standard Test Method for Evalua...

Aim The aim of this study is to determine the effectiveness of stevia as a daily mouthrinse among 12-15 year-old schoolchildren in Nellore District, Andhra Pradesh. Materials and Methods A randomized, controlled triple blind trial was carried out among 108 children in B. V. S Municipallity Girls High school in Nellore. Children were randomly allocated into four groups comprising 27 in each gr...

The aim of this study was to evaluate the effects of different irrigants on sealer-dentin bond strength when using Real Seal. Thirty single-rooted teeth were divided into 3 groups. In one group, the teeth were irrigated with 3 mL of 2.5% NaOCl after each file change, flushed with 17% EDTA for 3 min and finally rinsed with 3 mL of 2.5% NaOCl. In the other two groups, rinse with NaOCl was replace...

BACKGROUND Several studies have demonstrated that oral care with chlorhexidine gluconate (CHG) 0.12% solution reduces the incidence of ventilator-associated pneumonia (VAP) in mechanically ventilated patients with endotracheal tubes in the ICU. Minimal evidence shows the effectiveness of any oral care protocols in preventing VAP in mechanically ventilated patients with tracheostomies in a step-...

twice daily and body washes with 4% chlorhexidine gluconate soap solution for five days.6 Four of these five patients underwent a successful process of MRSA decontamination with nasal mupirocin and body washing with chlorhexidine. The fifth patient could not be assessed due to early death. Only one patient remained VRE-colonised and no deaths were related to the outbreak. Overall, the estimated...
