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

Figure 7

Coca Cola (×700). (a–i) White ovoid outlines show erosion in the same areas for enamel, ECJ, and dentine. Red arrows indicate obvious locations of change. There is minimal abrasion in (c), as enamel is dense, hard, and resistant to the brushing. But white outline in (e) shows erosion, and red arrows show loss of surface material from brush abrasion in (f). These SEM results are consistent with the calcium dissolution from swishes in Figure 3.
