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

Figure 8

Coca Selection (×700). 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 red arrows from brush abrasion are clearly visible in (f); the surface cracks while enlarged from erosion appear narrower and less numerous, as the soft superficial material is lost to the action of the brush. These SEM results are also consistent with the calcium dissolution from swishes in Figure 3.
