Abstract
Aim: To assess the effect of coca cola and diet coca cola on surface enamel roughness.
Materials and Method: In this vitro study, there were 8 teeth extracted and these specimens were prepared with 4 teeth immersed with coca cola and 4 teeth in diet Coca Cola of 40ml at room temperature for 5 minutes each. The enamel micro hardness of enamel was tested using Vickers hardness test. On each specimen, one indentation of 100 μm were made using a load of 25 gf for 5 s in a micro durometer and it was done as a single-blind test and the final results were further compared using t-test.
Results: There has been considerable reduction in enamel hardness when the teeth are dipped in coca cola and slight and negligible reduction in hardness when dipped in diet coca cola. Mean Difference in Coca Cola - 84.05 and DIET Coca Cola - 16.725. All the teeth except those exposed to Coca Cola showed a statistically significant decrease in the surface VHN (p < 0.05).
Conclusion: The results of this study showed significant reduction in the enamel hardness after treating with coca cola, whereas very minimal reduction in enamel hardness when treated with diet coca cola.
