Effect of environment on genotypic diversity of Acitnomyces naeslundii and Streptococcus oralis in the oral biofilm
Article Abstract:
The genotypic diversity of Acitnomyces naeslundii genospecies 2 and Streptococcus oralis strains isolated from two sound approximal sites in all subjects who were either caries active or caries free was investigated. Results suggest that environmental stress may modify a biofilm such that the diversity of the niches is increased and that these niches may be successfully exploited by some members of the microbial community.

Phenotypic and genotypic selection of microbiota surviving under dental restorations
Article Abstract:
The effects of sealing infected carious dentine below dental restorations on the phenotypic and genotypic diversity of the surviving microbiota are investigated. A hypothesis that the microbiota would be subject to nutrient limitation or nutrient simplification, as it would no longer have access to dietary components or salivary secretion for growth is presented.

Genotypic heterogeneity of Streptococcus oralis and distinct aciduric subpopulations in human dental plaque
Article Abstract:
Streptococcus oralis may be involved in the formation of dental plaque. Most people have several distinct genotypes in their mouth and studies of couples indicate that the bacterium can be orally transmitted.
