COMPARATIVE EVALUATION OF SURFACE ROUGHNESS OF TWO DIFFERENT COMMERCIALLY AVAILABLE SELF CURE ACRYLIC RESIN POST EXPOSURE TO VARIOUS CARBONATED BEVERAGES- IN VITRO STUDY

Abstract

Introduction : Resin composites have been used in dentistry extensively because of their excellent esthetics properties. Resin fillings, also called composite, white fillings or bonding, can make a significant improvement in the appearance of teeth in a short period of time. Dentists use resin to repair small cavities or chips in front teeth or to fill cavities cosmetically in the back teeth

Materials and methods: Commercially available self cure resin was chosen for the present study. 16 samples were prepared using self cure resin restorative material. 16 pellets of self-cure were prepared by  packing into silicone molds. The surface roughness value after immersing the material was determined using the Stylus profilometer. The surface roughness value of self cure resin before and after immersing in carbonated beverages were obtained and tabulated. All the data were analyzed by using SPSS version 21.0 (IBM Inc, Armonk, NY, USA).  Using the Chi- square test data was analyzed for the association graph. Bar diagrams were used to represent output variables.

Results: In this study, the result shows that after post immersion the values are being reduced in both the brands. Among the materials tested, better results were obtained with Trevalon Hi followed by Meliodent and DPI. Among the polishing methods used, superior results were obtained with universal polishing paste followed by polishing cake; Pumice and Gold rouge.

Conclusion: It can be concluded that surface roughness of two different types of resins decreases with exposure to carbonated drinks.
