Abstract
The purpose of this study was to verify cognition of soft drinks intake in university students and to identify correlation between the degree of enamel demineralization and soft drinks intake.
The survey study for cognition of soft intake proceeded with 239 university students lived in Pusan.
The effect soft drinks to enamel demineralization were investigated using soda drink, 100% orange juice, ion drink, and yoghurt. Bovine enamel specimen which 300-400 Vickers Hardness Number (VHN) were selected and immersed in each soft drink for 24 hours. The difference of micro-hardness was identified with VHN and micro-structure of enamel surface was confirmed with SEM image.
University students had a tendency to choice soft drinks with their calorie and spice and hardly consider the content of calcium. In demineralization study, yoghurt group showed the most effect of demineralization (-Δ 357.9 VHN) and the minimum effect was verified in soda drink (-Δ 201.6 VHN).
The micro-structure of demineralized samples was decolorized around enamel rods and the loss of their mineral component was observed in SEM images. In conclusion, yoghurt drink had the most influence on demineralization of enamel as compared with soda, orange juice, and ion drink.
