Introduction: The ultimate goal of endodontic treatment is to eliminate the bacterial infection in the root canal system. While mechanical debridement combined with chemical irrigation removes the bulk of microorganisms, residual bacteria are readily detectable in approximately one-half of teeth just prior to obturation. Laser light can be used to destroy bacteria. This in vitro study was perfo...

Balish, Edward (Syracuse University, Syracuse, N.Y.), and A. W. Phillips. Growth and virulence of Candida albicans after oral inoculation in the chick with a monoflora of either Escherichia coli or Streptococcus faecalis. J. Bacteriol. 91:1744-1749. 1966.-Bacterial protection against intestinal infection by Candida albicans was investigated in chicks with a monoflora of either Escherichia coli ...

OBJECTIVE To determine the E. faecalis biofilm formation on the surface of five adhesive systems (AS) and its relationship with roughness. STUDY DESIGN The formation of E. faecalis biofilms was tested on the surface of four dual-cure AS: AdheSE DC, Clearfil DC Bond, Futurabond DC and Excite DSC and one light-cure antimicrobial AS, Clearfil Protect Bond, after 24 hours of incubation, using the...

patients and methods one hundred thirty-eight clinical specimens collected from different wards of imam reza hospital were identified to the species level by biochemical tests. antimicrobial susceptibility tests against kanamycin, teicoplanin, streptomycin, imipenem, ciprofloxacin, and ampicillin were performed by the disk diffusion method. the minimum inhibitory concentrations of gentamicin, s...

Combinations of either brodimoprim or trimethoprim plus either carbenicillin, gentamicin, ciprofloxacin or rifampicin showed synergy at sub-inhibitory concentrations against both Enterococcus faecalis NCTC 5957 and 775. Brodimoprim alone and in combination showed greater antibacterial activity against both strains of E. faecalis than trimethoprim. MBCs of brodimoprim and trimethoprim were 14.4 ...

Enterococcus faecalis is increasingly becoming an important nosocomial infection opportunistic pathogen. E. faecalis can easily obtain drug resistance, making it difficult to be controlled in clinical settings. Using bacteriophage as an alternative treatment to drug-resistant bacteria has been revitalized recently, especially for fighting drug-resistant bacteria. In this research, an E. faecali...

i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...

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...

Xenorhabdus nematophila engages in a mutualistic association with the nematode Steinernema carpocapsae. The nematode invades and traverses the gut of susceptible insects. X. nematophila is released in the insect blood (hemolymph), where it suppresses host immune responses and functions as a pathogen. X. nematophila produces diverse antimicrobials in laboratory cultures. The natural competitors ...

This aim of this study was to assess the ability of manual or rotary instrumentation associated with photodynamic therapy (PDT) to reduce Enterococcus faecalis using three combinations of light/photosensitizers: toluidine blue O/laser, fuchsin/halogen light and fuchsin/LED. Twenty deciduous molars were selected and contaminated with Enterococcus faecalis (McFarland 0.5 scale). Working length de...
