In dentistry, residual infection remains a major cause of failure after endodontic treatment; many of these infections involve Enterococcus faecalis. In the current study, we explored the possibility that blue light activated photosensitizers could be used, in principle, to inactivate this microbe as an adjunct disinfection strategy for endodontic therapy. Three blue light absorbing photosensit...

Article history: Received on: 27/08/2013 Revised on: 19/09/2013 Accepted on: 02/10/2013 Available online: 31/10/2013 Aim of the study was to investigate the anti-bacterial potential of curcumin, against standard strains of common endodontic bacteria. The bacterial strains of Streptococcus mutans (ATCC 35668), Actinomyces viscosus (ATCC 10048), Lactobacillus casei (ATCC 334), Porphyromonas gingi...

Curcumin, an important constituent of turmeric, is known for various biological activities, primarily due to its antioxidant mechanism. The present study focused on the antibacterial activity of curcumin I, a significant component of commercial curcumin, against four genera of bacteria, including those that are Gram-positive (Staphylococcus aureus and Enterococcus faecalis) and Gram-negative (E...

introduction: the purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and mta. methods: forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. the samples were divided randomly into three experimental (n=13) and two control groups (n=3). all teeth were instrume...

Root canal disinfection is one of the main factors governing success of endodontic therapy. Antimicrobial photodynamic therapy (aPDT) is presented as a promising antimicrobial therapy that can eliminate microbiota present in infected root canal systems. In this study, a series of experiments investigated the effects of aPDT on cell viability and biofilm degradation ability of endopathogenic mic...

introduction: the aim of this study was to compare the antimicrobial effects of 2.5% sodium hypochlorite (naocl), 2% chlorhexidine gluconate (chx) and biopure mtad (mtad) on enterococcus (e) faecalis -contaminated root canals of human extracted teeth. materials and methods: seventy human intact extracted single-rooted teeth with straight root canal randomly divided into 5 groups: positive contr...

Resistance to linezolid among Enterococcus faecium and Enterococcus faecalis isolates has been reported in patients who receive a prolonged course of the drug. We report two cases of linezolid-resistant Enterococcus faecalis that occurred in patients who previously received linezolid for infections with vancomycin-resistant Enterococcus faecium. Both isolates had the G2576U mutation in the 23S ...

Enterococcus species were considered as non-pathogenic bacteria until recognized as an important cause of bacterial endocarditis in 1899. During the past decade, there has been a worldwide increase in occurrence of enterococcal infections. Though more than 28 enteroccocal species described, Enterococcus faecalis and Enterococcus faecium are isolated most frequently. This might be explained by t...
