Clinical Implications of Power Toothbrushing on Fluoride Delivery: Effects on Biofilm Plaque Metabolism and Physiology
(a) S. mutans biofilm is grown on hydroxyapatite slides with microelectrode measurements revealing a drop in pH within the first 4 minutes after addition of 2 % sucrose. Removing sucrose and adding F raises pH after 6-7 minutes of intervention (graph redrawn from ). (b) Variability of microelectrode profiles within the biofilm after sucrose addition. In location 1 pH dropped to 4.2, while little change was seen in location 3.
