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

Figure 4

Phosphorous concentrations were expressed as mg/L from the source (bottled water or can) and swished test drinks. Aquafina water was used as control for all groups. Measures were assessed using ICP-OES. The phosphorus content of control (water) remains constant for each group, but the phosphorus content of swished water probes obtained from 3 separate cohorts (six volunteers for each group) vary. There is wide variation of phosphorous concentrations when swishes with cola from subjects with teeth are compared to swishes of cola from subjects without teeth. This is because there are variable amounts of phosphoric acid in the colas and phosphates in subjects’ saliva; some reactive calcium-binding phosphorous is in stimulated saliva.
