Interproximal wire-telemetric plaque pH data were obtained from five volunteers after they ate milk chocolate bars, raisins, chocolate wafer cookies with cream filling, cupcakes with icing and cream filling, and cherry pies. All the foods produced rapid decreases in plaque pH for extended periods. In a second set of test sessions, volunteers chewed sugarless gum for 10 minutes, starting 15 minutes after they ate the snack food. In all cases, the gum chewing caused a rapid increase in plaque pH. The pH remained at a level considered safe for teeth for 30 minutes after chewing the gum.
在五名志愿者食用牛奶巧克力棒、葡萄干、带奶油夹心的巧克力威化饼干、带糖霜和奶油夹心的纸杯蛋糕以及樱桃派之后,获取了邻面钢丝遥测菌斑pH数据。所有这些食物都会使菌斑pH在较长时间内迅速下降。在第二组测试环节中,志愿者在吃完休闲食品15分钟后开始咀嚼无糖口香糖10分钟。在所有情况下,咀嚼口香糖都会使菌斑pH迅速上升。咀嚼口香糖后,pH在30分钟内保持在对牙齿而言被认为安全的水平。
