| Research Abstract |
ISFET electrode was fixed to maxillary first molar buccal surface (UPB) and maxillary front tooth labial surface (UAB) of the subject, and pH was monitored approximately six hours when the subjects were sleeping after mouth rinsing with a soft drink (pH 3.8). As a result, after having suddenly dropped to pH 3.8, the pH at UPB returned to the beginning state immediately, and decreased to pH 6.5 at just getting up, but at UAB the pH did not return to the beginning pH. Bovine enamel pieces were fixed to UAB and UPB of the subject, and decalcification degree was measured by QLF. As a result of having stopped brushing for four days, the significant difference did not recognized between both.
