Influence of soft drinks on dental enamel: An in vitro study

This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tukey HSD test. Loss of enamel was observed in Coca Cola, Cappy and Sprite groups. Coca Cola was significantly higher erosive potential in 180 minutes than other soft drinks (p < 0.05). Ayran was no sign of erosive potential in all time. It can be concluded that the composition of the beverages had a significant effect on dental erosion, so consumption of Ayran can be advised.
