Actinomyces spp have been increasingly associated with endodontic infections. However,
the antimicrobial susceptibility of this genus has not been studied extensively. The objective …

Background/aims: Periodontal infections with Actinobacillus actinomycetemcomitans seem
to be refractory to conventional therapy. The aim of the present study was to test the in vitro …

Actinomyces israelii has been repeatedly implicated as a cause of failure of endodontic
therapy. This study investigated the antimicrobial effect of antibiotics as well as intracanal …

Species of Actinomyces have been associated with endodontic treatment that failed to heal.
In this study polymerase chain reaction was used with a pair of universal primers for …

The main reason for root canal treatment failure is the persistence of microorganisms after
therapy, or the recontamination of the root canal system due to an inadequate seal. In the …

Objective: This study was conducted to assess the susceptibility of human clinical isolates of
Actinomyces species to 12 antimicrobial agents. Methods: Human clinical isolates of …

Objectives. The poor sensitivity of phenotypic identification techniques has hampered the
taxonomic differentiation of Actinomyces. Hence we developed a sensitive and specific …

Background: Antibiotic resistance has been increasingly described among bacterial species
colonizing periodontal pockets, particularly in Prevotella and Porphyromonas spp. strains …

Actinomycosis is considered to be a rare disease in the oral region. A retrospective study of
files of the University of Nebraska Medical Center College of Dentistry, Department of …

The aim of the present study was to identify Actinomyces occurring in infected dental root
canals. Out of twenty-five isolated Actinomyces strains, four were A. israelii, four were A …
