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

Figure 11

Diet Cola Selection (×700). White outlined areas clearly show erosion with surface crenellations and profusion of shrinkage cracks from calcium loss when comparing (a), (d), and (g) to (b), (e), and (h). Minimal abrasion is present on the enamel, but loss (red arrows) from brush abrasion is clearly visible in (f); the surface cracks while enlarged from erosion, appear narrower and less numerous, as the soft superficial material is lost to abrasion. Red arrows, (g)–(i), show that 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.
