Abstract
Aim
to monitor microbial shifts during dental biofilm re-development
Methods
Supra and subgingival plaque samples were taken separately from 28 teeth in 38 healthy and 17 periodontitis subjects at baseline and immediately after tooth cleaning. Samples were taken again from 7 teeth in randomly selected quadrants during 1, 2, 4 and 7 days of no oral hygiene. Samples were analyzed using checkerboard DNA-DNA hybridization. Species counts were averaged within subjects at each time point. Significant differences in counts between healthy and periodontitis subjects were sought using the Mann-Whitney test.
Results
Total supra and subgingival counts were significantly higher in periodontitis on entry and reached or exceeded baseline values after day 2. Supragingival counts of Veillonella parvula, Fusobacterium nucleatum ss vincentii and Neisseria mucosa increased from 2 to 7 days. Subgingival counts were greater for Actinomyces, green and orange complex species. Significant differences between groups in supragingival counts occurred for 17 of 41 species at entry, 0 at day 7; for subgingival plaque these values were 39/41 taxa at entry, 17/41 at day 7.
Conclusions
Supragingival plaque re-development was similar in periodontitis and health, but subgingival species recolonization was more marked in periodontitis.
