Pop-Cola Acids and Tooth Erosion: An In Vitro, In Vivo, Electron-Microscopic, and Clinical Report

Figure 9

Diet Coke (×700). Outlined areas show erosion with minor surface changes from calcium loss when comparing (a), (d), and (g) to (b), (e), and (h). Minimal abrasionis is present on the enamel, but red arrows from brush abrasion are clearly (i). Red arrows show dentine tubules exposed from erosion appear clearer, wider, and more open as the soft surface material is lost to brush abrasion. These SEM results are also consistent with the calcium dissolution from swishes in Figure 3.
