Effects of different drinks on surface of autopolimerized acrylic resins after two polishing

Abstract

This study analyzed the surface roughness of an acrylic resin. The specimens were divided into 10 groups (n = 5): I - control mechanical polishing, II – mechanical polishing immersed in coffee, III – mechanical polishing immersed in coffee with sugar, IV – mechanical polishing immersed in Coca- Cola ®, V – mechanical polishing immersed in Coca-cola ®, VI – control chemical polishing, VII - chemical polishing immersion in coffee, VIII - chemical polishing immersed in coffee with sugar, IX - chemical polishing immersed in Coca-Cola ®, X - chemical polishing immersed in Coca-cola®. The analysis of variance showed significant differences between groups (p = 0.000). The Tukey test showed that immersion in coffee increased the roughness in both treatments, while immersion in Coca-Cola® wasn’t.
