Mean total DNA probe counts (× 105, ± SEM) of supragingival biofilm samples taken at entry (pre-cleaning), immediately post-cleaning and after 1, 2, 4 and 7 days of biofilm development. Significance of differences between clinical groups at each time point was determined using the Mann Whitney test. The bars represent mean total DNA probe counts and the whiskers the SEM at each time point.
