Abstract

Background: Exposure of soft drinks to enamel surface has effect in tooth erosion. Mild tooth erosion known as dentin hypersensitivity, that is signed by a sensation of pain because of thermal stimulation Method: Observational analytic research with cross sectional approach. A cluster sampling of Domenico Savio High School students(n=145) was required to fill a questionaire of soft drinks intake and examined for dentin hypersensitivity. Samples divided into three groups, which are rarely, occasionally, and rather frequently group. The data, which was a primary data, collected from direct measurements of pain intensity by Visual Analogue Scale. Dental pain was stimulated by cold water to the first premolar dextra and sinistra. The data was analyzed with SPSS for Windows. Kruskal-Wallis test was formed, followed by Mann-Whitney test. Result: This study showed that pain intensity in dentin hypersensitivity had range between 0 until 4 in VAS. There were 66,2% samples showed 0 in VAS, it meant that they didn’t suffer dentin hypersensitivity. Kruskal-Wallis test showed p=0,019 with df.=2. Mann-Whitney test showed a significant difference of pain intensity in rarely-occasionally and rarely-rather frequently groups. Occasionally and rather frequently groups didn’t show significant difference. Conclusion: There is a significant difference of dentin sensitivity in various level of soft drinks consumption frequency. Increasing of soft drinks consumption frequency followed by the increasing of dentin sensitivity. Key words: soft drinks, dentin hypersensitivity, Visual Analogue Scale
