Investigating the erosive effect of energy drink on human dental enamel surface morphology of permanent teeth by measuring the surface roughness with profilometer

摘要

Dental erosion, which is a loss of dental hard tissue, is a big problem in today's world. One of the main reasons of this problem is the acidic and carbonated beverages among which I have chosen the energy drinks. This experiment is focused on the erosive effect of energy drinks on dental enamel surface morphology of human permanent third molar teeth with the research question: "How is the dental enamel surface morphology of human permanent third molar teeth effected by increasing exposure time interval of permanent teeth in energy drink while the temperature, pressure, type of energy drink is kept constant, by measuring the surface roughness with contact profilometer?" Would increasing exposure time redound the dental erosion? For this experiment 7 freshly extracted caries free human permanent third molar teeth were used. Samples were placed in a plastic container with 100 mL of energy drink and stored at 36,5°C. The surface roughness of 7 teeth were measured by contact profilometer at the end of the 1st day, 1st week, 1st month, 3rd month and 6th month. The test solution was changed daily. The data were statistically analyzed by Wilcoxon Signed-Rank Test.udThe results showed that there was a clear rise in surface roughness on dental enamel of permanent third molar teeth as the exposure time interval of permanent teeth in energy drink is increased. There was a significant difference between the surface roughness values from the beginning until the end of 6th month. The results of this experiment supported my hypothesis, in which; there would be a significant dental enamel loss caused by energy drink, was stated.
