本研究的目的是研究在饮用无糖可乐型软饮料期间和之后牙齿表面的口腔内pH反应与牙齿侵蚀的关系。六种不同的饮酒方法按随机顺序进行了测试：握住；short-sipping;里喝;吞;刺骨的;和吸。在两组个体中采用了两种pH测量方法。在第一个系列中，使用微触法测量了12名健康成年人在三个牙齿腐蚀易发部位的pH值：11个腭；11口;在中颊尖16的尖端。在第二个系列中，采用遥测法测量6名健康个体的pH值，通过玻璃电极在指定的近似区域连续记录pH值。这两个系列显示了类似的结果，尽管遥测法通常记录更大的pH下降。在吞咽之前将饮料含在嘴里会导致最明显的pH值下降，其次是长时间啜饮的方法。吞咽仅导致ph值小幅下降。使用微触法分析时，发现三个口腔内部位没有差异。这项研究的结论是，饮用方法会强烈影响牙齿表面的pH值，从而增加牙齿侵蚀的风险。因此，在与牙齿侵蚀有关的饮食咨询中纳入关于饮酒方法的建议似乎是适当的。
The aim of this investigation was to study the intraoral pH response on tooth surfaces in relation to dental erosion during and after drinking a sugar-free cola-type soft drink. Six different methods of drinking were tested in a randomized order: holding; short-sipping; long-sipping; gulping; nipping; and sucking. Two methods of pH measurement were used in two series of individuals. In the first series, pH was measured by using the microtouch method in 12 healthy adults at three dental erosion-prone sites: 11 palatally; 11 buccally; and at the mesiobuccal cusp tip of 16. In the second series, pH was measured by using the telemetric method in 6 healthy individuals, producing continuous recordings of pH by means of a glass electrode in a specified approximal area. The two series showed similar results, although the telemetric method generally recorded larger pH falls. Holding the drink in the mouth before swallowing led to the most pronounced pH drop, followed by the long-sipping method. Gulping resulted in only a small decrease of pH. No differences among the three intraoral sites were found when analyzed by using the microtouch method. The conclusion from this study is that the drinking method strongly affects tooth-surface pH and thereby the risk for dental erosion. It therefore seems appropriate to include advice on the method of drinking in dietary counseling related to dental erosion.
