Abstract
The purpose of the present study was to describe the bacterial diversity in the oral cavity of the elderly without root caries using bacterial microarrays, and to determine the site- and subject-specificity of bacterial colonization. Samples were collected from the tongue dorsum, mucosa of the buccal fold, hard palate, supragingival plaque from sound root surfaces, and subgingival plaque from the same roots. A new 16S rRNA gene based microarray method was used for the simultaneous detection of approximately 300 bacterial species. Overall, 175 species and clusters were detected, representing 8 phyla. Species belonging to the genera

Species belonging to the genera <italic>Streptococcus</italic>, <italic>Veillonella</italic> and <italic>Fusobacterium</italic> were common in all sites. The number of species per subject varied from 51 to 81. Statistical analyses revealed about 40 species or clusters with significant associations with at least one of the sites. The bacterial diversity was highest in the cheek and palate regions. Species typically associated with caries and periodontitis were detected rarely or not at all. The oral bacterial flora of the elderly appears to be diverse, and to a large extent site- rather than subject-specific.</p></div></front></TEI><affiliations><list></list><tree><noCountry><name sortKey="Grinde, Bj Rn" sort="Grinde, Bj Rn" uniqKey="Grinde B" first="Bj Rn" last="Grinde">Bj Rn Grinde</name><name sortKey="Olsen, Ingar" sort="Olsen, Ingar" uniqKey="Olsen I" first="Ingar" last="Olsen">Ingar Olsen</name><name sortKey="Paster, Bruce J" sort="Paster, Bruce J" uniqKey="Paster B" first="Bruce J." last="Paster">Bruce J.
