Objective: To evaluate the effect of 2.5% sodium hypochlorite and four intracanal medications on Candida albicans harvested inside root canals. Materials and methods: The contaminated canals were irrigated with sterile saline and then treated as follows: filled with (1) calcium hydroxide and saline, (2) calcium hydroxide and 2% chlorhexidine gluconate, (3) zinc oxide and 2% chlorhexidine glucon...

This aim of this study was to evaluate and compare the efficacy of different chemical methods to disinfect gutta-percha cones (GP). Eighty-six size 80 GP cones were used. The cones were contaminated by immersion in saliva and Enterococcus faecalis. Four chemical agents were used: 1% sodium hypochlorite (G1), 2% chlorhexidine gluconate (G2), 10% povidone iodine (G3) and 0.9% saline solution (G4)...

PURPOSE Antiseptic mouth rinses are widely recommended and marketed to improve oral health. This article summarizes current studies on the comparative effectiveness of selected antiseptic mouth rinses in controlling plaque and gingivitis, as well as risks associated with daily exposure, including salivary flow rate, oral cancer and wear of composite restorations. METHODS Electronic database ...

BACKGROUND Chlorhexidine bathing has been associated with reductions in healthcare-associated bloodstream infection. To determine the impact and sustainability of the effect of chlorhexidine bathing on central venous catheter-associated bloodstream infection, we performed a prospective, 3-phase, multiple-hospital study. METHODS In the medical intensive care unit and the respiratory care unit ...

BACKGROUND The aim of this study was to compare the antibacterial efficacy of endemic Satureja Khuzistanica Jamzad (SKJ) essential oil as root canal irrigation versus 2.5% sodium hypochlorite and 2% chlorhexidine gluconate. METHODS In current in vitro experimental study, fifty four single-rooted teeth were randomly divided into 6 groups of 9 samples: 2.5% sodium hypochlorite (NaOCl), 2% chlor...

OBJECTIVES The purpose of this study was to evaluate in situ the occurrence of corrosion in the soldering point areas between the wire, silver brazing and band in Haas expanders. MATERIAL AND METHODS Thirty-four 7-12-year-old patients who needed maxillary expansion with a Haas expander were randomly assigned to two groups of 17 individuals each, according to the oral hygiene protocol adopted ...

Methicillin-resistant Staphylococcus aureus (MRSA) can grow as structured biofilm in different surfaces, including oral mucosa and denture surfaces. Such biofilms can be released into the oral fluids and aspirated, causing systemic infections such as aspiration pneumonia. This study evaluated the efficacy of two disinfectant solutions and microwave irradiation in disinfecting acrylic specimens ...

Fifty volunteers randomly assigned to one of five hand washing agents (10 subjects per agent)--a nonantiseptic liquid soap (control), an antiseptic hand rinse containing 60% isopropyl alcohol (IPA) with emollients (Alc A), an antiseptic hand rinse containing 70% IPA and 0.5% chlorhexidine gluconate with emollients (Alc B), an antiseptic containing 4% chlorhexidine gluconate and 4% IPA (CHG), an...

BACKGROUND Decreasing the levels of bacteria in the oropharynx should reduce the prevalence of nosocomial pneumonia. OBJECTIVES To test the effectiveness of 0.12% chlorhexidine gluconate oral rinse in decreasing microbial colonization of the respiratory tract and nosocomial pneumonia in patients undergoing open heart surgery. METHODS A prospective, randomized, case-controlled clinical trial...

background: the aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of enterococcus faecalis on gutta-percha points disinfected with four disinfectants. materials and methods: a total of 50 gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalko...
