Pop-Cola Acids and Tooth Erosion: An In Vitro, In Vivo, Electron-Microscopic, and Clinical Report
Figure 1
pH comparison among pop-Cola drinks. The pH levels of the six analyzed cola drinks are all significantly below the critical pH (pH 5.5) of Calcium hydroxyapatite ( Student-). The diet colas are not necessarily more acidic; regular Pepsi Cola has the lowest pH (pH 2.53), while Diet Selection Cola is the highest pH (pH 3.40).
