EFFECT OF FIZZY DRINKS ON THE SURFACE ROUGHNESS OF LIGHT CURE DENTURE BASE RESIN - AN IN VITRO STUDY

Abstract

Introduction: Consumption of beverages and fizzy drinks has increased enormously among the people. Carbonated drinks like coke, pepsi and sprite have gained lots of consumers. Acrylic resins may be self, light-cured or heat cured. The aim of this study is to evaluate the effect of fizzy drinks on the surface roughness of light cure denture base resin.

Materials and Methods: 10 samples were prepared using light cure denture base resin material. Three different beakers were taken containing distilled water, coca cola and 7up. The samples were immersed for a period of 24 hours. Initial surface roughness was measured before immersion into fizzy beverages. It was measured for each specimen using a stylus profilometer - Mitutoyo SJ310. Measurements were obtained by placing a stylus attached to the device on the surface of the sample and the results were observed on the monitor screen. The surface roughness of the material after immersion period was again measured using a stylus profilometer. The surface roughness value of light cure denture base resin before and after immersing in fizzy drinks were obtained and tabulated. The mean value was obtained and the results were analysed using SPSS software version 22.0 and the results were represented graphically.

Results: There were no significant changes in Ra, Rq and Rz value of light cure denture base resin samples before and after immersion in fizzy drinks. Paired T test was performed and the p value obtained was 0.423 >0.05, hence statistically insignificant.

Conclusion: From this study, it can be concluded that fizzy drinks do not affect the surface roughness of light cure denture base resin.
