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.

将ISFET电极固定在受试者上颌第一磨牙颊面（UPB）和上颌前牙唇面（UAB）上，用软饮料（pH值3.8）漱口后，在受试者睡觉约6小时时监测pH值。结果，当pH值突然降至3.8时，UPB处的pH值立即恢复到初始状态，刚起床时又降至pH值6.5，但在UAB处，pH值并没有恢复到初始状态。将牛牙釉质片固定在受试者的UAB和UPB上，用QLF测量脱钙程度。由于停止刷牙四天，两者之间的显著差异没有被发现。
