Erosion is believed to be the predominant cause of teeth wear in children and young adults, although there will always be a contribution from attrition and abrasion. The pH of cola is known to be low and have, therefore, been implicated in the increasing incidence of erosion.

The aim of present study was to evaluate the effect of cola on the progression of erosive demineralization in human enamel using demineralization model in vitro. Six groups of human enamel slap were immersed(5 min each bath) in fresh cola, with immersions taking place with or without agitation, and under 3 regimes of frequency intake(low in-take, 1 immersion£¯day; medium, 5£¯day; high, 10£¯day). Quantitative assessments of surface erosion were done over an 8-day interval using surface microhardness testing.

1. The average pH of cola was 2.5, which was acidic enough to cause tooth erosion.

2. All the enamel specimen exposed to cola showed erosion like lesions and surface hardness decreased in proportion to the length of immersion (p£¼0.05).

3. The surface hardness of enamel decreased in proportion to the frequency of immersion (p£¼0.05).

4. Increased degassing from the drink by gitation accelerated the enamel softening compared with those without agitation.
