Abstract
A transistor pH electrode (pH-ISFET electrode) was placed in each of four human mouths and bacteria were allowed to accumulate on it for 1, 2 or 3 days. Changes of plaque pH were measured in situ after application of sucrose solution (0.1, 1 or 3%) and, then, quick pH recovery by mouth-rinses with water was estimated. Although the acidic pH after application of 0.1% sucrose was easily and quickly recovered from by a few mouth-rinses with water, rather frequent mouth-rinses with water were required to recover from the acidic pH of 2- or 3-day-old plaque after the application of a 1 or 3% sucrose solution. For example, 15 (mean, n = 4) mouth-rinses with water were required for the 3 day-old plaque pH to recover after the application of 3% sucrose solution.
