... is sparse. We compared the ability of Streptococcus and Actinomyces species to adhere to hydroxyapatite coated by rat saliva (rsHA) and human saliva (sHA). We also explored the influence of glucan synthesized in situ on the adherence of organisms. We show that each strain of organism has a distinct binding...

... in the shallow and middle layers of dentine from fissures and smooth surface coronal carious lesions than from the deep layers. In root surface caries, Actinomyces spp. were the predominant bacteria, and were present at higher levels in the deep layer of root lesions than in the shallow and middle layers...

... for higher levels of Streptococcus mutans in plaque from active lesions compared with sound root surfaces, whereas an inverse relationship was noted for the Streptococcus oralis group. No significant differences in the Actinomyces naeslundii counts were detected. In conclusion, the 12-month prophylactic...

... composition, the structural organization of the deposits, and the presence or absence of crystal-like material. However, in all individuals a layer of densely packed gram-positive bacteria resembling Actinomyces was consistently present close to the enamel surface. In 1 individual the microbial deposits were...

... upper premolars and two first molars. Samples were processed anaerobically on media that were selective for the oral Streptococcus spp ., Haemophilus spp ., and Actinomyces spp., as well as supplemented blood agar for identification of gram-negative bacterial groups and total cultivable flora. NAD...

...S. Fure; C.G. Emilson The supplementary effect of chlorhexidine varnish and resin on the reappearance of mutans streptococci and Actinomyces spp. on root surfaces after chlorhexidine gel treatment was studied. In 8 subjects with many restored tooth and exposed root surfaces, highly colonized...

...K. Komiyama; R.J. Gibbons The influence of saliva on lactose-reversible adherence between strains of Actinomyces viscosus and Streptococcus sanguis or Streptococcus mitis was investigated. Because saliva agglutinated these organisms, it was necessary to develop models for studying streptococcal...

... and palatal surfaces of the primary first incisor and a control site, the labial of the primary first mandibular incisor, were sampled. The plaque samples were analysed for the presence and numbers of members of Streptococcus , Actinomyces , Lactobacillus and Veillonella . The results showed significant...

...B.A. Burt; W.J. Loesche; S.A. Eklund With standardized plaque sampling techniques, bacterial populations were studied on the fissures of 500 unrestored lower first permanent molars in 279 children 6–7 years old at the beginning of a 2-year period. Samples were taken every 6 months. Actinomyces...

...Prudence E. Hill; K.W. Knox; R.G. Schamschula; Josie Tabua The cultivable flora was examined in seven plaque samples collected from New Guinea indigenes with active radicular caries. The predominating organisms were streptococci. Actinomyces and related genera accounted for most of the remaining...

... low levels, repeated treatment appears to be necessary. Flossing, with or without iodine, does not eliminate S. mutans from interproximal sites and does not significantly alter the proportion of actinomyces. 17 11 2009 © 1980 S. Karger AG, Basel 1980 Copyright / Drug Dosage / Disclaimer...

Microbial acid adaptation and subsequent acid selection of ‘low-pH’ non...

However, the numbers and proportions of Gram-positive pleomorphic rods, primarily Actinomyces naeslundii , increased in 6-hour samples from subjects using...

Busscher This study compared removal of pairs of co-adhering and non-co-adhering oral actinomyces and streptococci from salivary pellicles by manual, rotating/oscillating electric and sonic toothbrushes, applying...

... density at 660 nm of the cultures were measured. Fermentation ability was measured by pH ≤5.5, growth by an OD 660 of ≧0.5. Of the clinical isolates, 33% fermented palatinose, and 69% of these were Actinomyces species. All of the palatinose-fermenting bacterial strains fermented trehalulose, 25% fermented...

...G. Tang; H.K. Yip; L.P. Samaranayake; G. Luo; E.C.M. Lo; C.S. Teo Very limited molecular epidemiological data are available on the role of Actinomyces spp. in the pathogenesis of caries in the primary dentition. Therefore, we investigated their distribution in supragingival plaque of ethnic Chinese...
