Abstract

Composite resins can get discolored for a variety of reasons, both internal and external. Therefore, it is of interest to assess a composite resin's surface roughness and color stability following exposure to artificial saliva, orange juice, tea and Coca-Cola on days six, twelve and twenty-four. Based on beverages, 48 composite resin disc specimens were randomly assigned to four equal groups: Group 1-artificial saliva- control, Group 2-Coca-Cola, Group 3-tea and Group 4-orange juice. Surface roughness (Ra) and color change (ΔE) baseline readings were collected using a profilometer and digital image analysis technique in the CIE l*a*b scale. The readings (ΔE) were then obtained on the sixth, twelfth and twenty-fourth days after exposure to the corresponding beverages. The Coca-Cola group had the highest surface roughness (Ra) value and color variations, followed by orange juice and tea. The control group (artificial saliva) had the lowest surface roughness value.
