A-16686, a new glycoproteide antibiotic from Actinoplanes sp., was evaluated as a potential antiplaque agent in comparison with chlorhexidine, benzalkonium chloride, and cetylpyridinium chloride. A-16686 had good activity against gram-positive organisms associated with dental plaque (various streptococci, Streptococcus mutans in particular, lactobacilli, Actinomyces viscosus, and Actinomyces na...

This study was an attempt to develop a fluorescent-antibody (FA) test to differentiate Actinomyces israelii and A. naeslundii as an aid in their laboratory identification. Two strains of A. israelii (X522 and A601) and two strains of A. naeslundii (X454 and X600), which had received intensive study by several investigators, were used for the immunization of rabbits. Working titers, based on tes...

AIM We aimed to assess caries experience and microbiota in systemically healthy children with black stain (BS) and non-discoloured plaque. METHODS Forty-six children with BS and 47 counterparts with non-discoloured plaque aged 7.9 ± 1.3 years were clinically examined. Dental caries was scored using WHO criteria. Samples of BS and non-discoloured dental plaque were collected from tooth surface...

Background: The soft tissue around dental implants forms a barrier between the oral environment and the periimplant bone and a crucial factor for long-term success of therapy is development of a good abutment/soft-tissue seal. Sol-gel derived nanoporous TiO2 coatings have been shown to enhance soft-tissue attachment but their effect on adhesion and biofilm formation by oral bacteria is unknown....

Aim: The study aimed at isolation and preliminary characterization of anaerobic bacteria from a special crossbreed of Muturu and N’Dama cattle found in parts of Nigeria. Study Design: The work investigated the suitability of the isolates in in vitro fermentation of biomass and evaluated the relationship between the bacterial flora and their ability to hydrolyse lignocellulosic materials from co...
