[The effects of Ketac Molar Aplicap glass-ionomer material on growth of cariogenic bacteria contained in the dental plaque].

Introduction: In the aging population, the prevalence of root caries has been observed, which is a characteristic feature of the elderly people. The most important element used in caries prevention is fluoride, which is derived from the air, diet or fluoride-containing preparations and materials, e.g.

[Influence of topical fluoridation of glass ionomer cements on inhibitory activity on cariogenic bacteria].

Glass ionomer cements are important options in restorative and preventive dentistry due to their adhesion to the tooth surface and fluoride release, which can decrease the risk of recurrent caries. The aim of this study was to define, in vivo, the influence of the topical use of fluoride gel on dental plaque bacteria growing on the glass ionomer cement. Fifteen patients were included into this study.

[Influence of the fluoride releasing dental materials on the bacterial flora of dental plaque].

The assessment of influence of silver-free, fluor releasing dental materials on dental plaque bacteria quantity. 17 patients were included into the study. 51 restorations were placed following manufacturers recommendations.

[Comparison of bacterial flora in the oral cavity of children and adults].

The aim of the study was to assess levels of occurrence and number of aerobic bacteria hemolysing and non-hemolysing, anaerobic bacteria, streptococci hemolysing and non-hemolysing, staphylococci, and bacteria responsible for tooth decay (Streptococcus mutans and Lactobacillus spp.) on oral cavity in children and adults. The results obtained indicate the difference of the level of occurrence of, aerobic bacteria hemolysing and non-hemolysing, anaerobic bacteria, streptococci hemolysing and non-hemolysing, staphylococci, and bacteria responsible for tooth decay (Streptococcus mutans and Lactobacillus spp.

[Production of glycocalyx by coagulase negative staphylococci isolated from the oral cavity].

The study was aimed at determination whether and how frequently coagulase-negative staphylococci persisting in human oral cavity possess the same feature. The material consisted of 255 strains of coagulase-negative staphylococci isolated from oral cavity of persons of both sexes and in differing age. Glycocalyx production by these strains was tested quantitatively by a colorimetric method.
