Introduction: Debridement of root canal using appropriately safe and effective irrigants is the key factor for long-term success. Purpose of this study was to compare the antibacterial effect of propolis with 5.25% sodium hypochlorite, and 2% chlorhexidine against enterococcus faecalis. Materials &Methods: In this study, 36 single-canal roots were used. The crown was removed and instrumentat...

Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...

The aim of this work was to study the antibacterial effect of coriander (Coriandrum sativum) essential oil against Gram-positive and Gram-negative bacteria. Antibacterial susceptibility was evaluated using classical microbiological techniques concomitantly with the use of flow cytometry for the evaluation of cellular physiology. Our results showed that coriander oil has an effective antimicrobi...

This study evaluated the in vitro antibacterial activity of conventional and experimental endodontic irrigants against Enterococcus faecalis. The following substances were evaluated by direct contact test: 2.5% sodium hypochlorite (NaOCl); 2% chlorhexidine (CHX); 1% peracetic acid. After different contact periods (30 s, 1, 3, and 10 min), a neutralizing agent was applied. Serial 10-fold dilutio...

background and objectives:increased antibiotic resistance as a result of using antimicrobial drugs and also their various adverse effects has caused that in recent years, investigation of medicinal plants beconsidered for discovering new medicinal resources against bacterial infections. this study was performed with the objective of determining the antimicrobial activity of aqueous and ethanoli...

A total of 330 lactic acid bacteria isolated from South African red wines during alcoholic and malolactic fermentations and 9 commercial malolactic bacteria starter cultures were screened for antimicrobial activity. Of the entire screened isolates, 26 strains, belonging to the species Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus hilgardii and Oenococcus oeni, showed activity ...

introduction : the aim of this in vitro study was to evaluate the antimicrobial activity of four intracanal medicaments on enterococcus faecalis (e. faecalis). methods and materials: fifty extracted single-rooted human teeth were prepared with standard method. after contaminating the canals with e. faecalis , the samples were divided into one control and four experimental groups ( n =10). the t...

Background: E. faecalis is a commonly recovered microbe in failing root canals. Due to limitations of currently popular endodontic irrigants, there is need to find novel antibacterial agents against E. Faecalis. Mupirocin is a broad spectrum antibiotic agent which is effective against gram positive organisms including MRSA. Purpose: The purpose of this study was to compare the antibacterial act...

The aim of this study was to analyze the antimicrobial activity and substantivity of Uncaria tomentosa Willd DC (cat's claw, CC) in root dentin contaminated with Enterococcus faecalis. Forty-eight human premolars were contaminated with E. faecalis (ATCC 29212) and randomly divided into four groups according to the irrigant used during chemomechanical preparation (CMP): CC group: 2% CC gel; CHX ...

Four naphtho-γ-pyrones (fonsecinones A and C and aurasperones A and E) were identified as potential antibacterial agents against Escherichia coli, extended-spectrum β-lactamase (ESBL)-producing E. coli, Pseudomonas aeruginosa, Enterococcus faecalis, and methicillin-resistant Staphylococcus aureus (MRSA) in an in vitro antibacterial screen of 218 fungal metabolites. Fonsecinone A (2) exhibited t...
