COMPARATIVE EVALUATION OF SURFACE ROUGHNESS OF COMMERCIALLY AVAILABLE LIGHT CURE RESIN POST EXPOSURE TO VARIOUS HOT BEVERAGES - IN VITRO STUDY

Abstract

Introduction: The persistent changes and advancement in the field of  helpful materials have prompted the advancement of different new age composite materials that display expanded strength, better surface properties, better color stability and improved polishability for better optical properties.

Aim: Aim of the study is to evaluate the surface roughness of the light cure resin material post exposure to the various hot beverages.

Materials and Methods: Commercially available light cure resin was used for the present study. Using silicone molds ten pellets of light cure resin material was prepared. And before and after immersion values of surface roughness of the material were calculated and the mean value was noted. The correlation test was done using SPSS software version 23.0 and paired sample statistics  was done and P < 0.05 is considered to be significant. The conduct was approved by the institutional review board.

Results: Surface roughness was time dependent as it increased with time. Furthermore, greater surface roughness was observed in all the groups at  tested time intervals. Ra and Rz values of post immersion value is less than pre immersion values (0.027) 

Conclusion: From this study it can be concluded that surface roughness of  commercially available light cure resin post exposure to various hot beverages.From the present study it can be resulted that comparative evaluation of surface roughness value of  the commercially available light cure resin post exposure to various hot beverages resulted that the mean value of the surface roughness post immersion is less when compared to the mean value of the surface roughness before the immersion of the material.
