The Impact of Immersion in Different Beverages on the Physical and Mechanical Features of Zirconia Restorations

Abstract: Objective: This study aimed to evaluate the modifications in surface micro-hardness & roughness of zirconium restoration after exposure to different types of beverages (coca-cola and red bull).Material and methods: Twenty specimens of Yttrium partially stabilized zirconium disc-shaped with identical size of 10 mm diameter and 1 mm of thickness were made by using of stereolithography file and then milled and sintered. They are divided into two major groups depending on the immersion beverages types (coca-cola and red bull). After exposure, they are subjected to hardness test by using a digital tester and roughness test by using a profilometer device.Results: The outcome of the current study represent there was a highly significant difference in the hardness and roughness value between both of the major groups. The highest mean value of hardness was for Red bull group which was (355.860 mm), while the lowest mean value was for coca cola group which was (313.810 mm). On the other hand, the highest mean value of roughness was for coca cola which was (2.2702mm), while the lowest value was for red bull group which was (0.9060mm).Conclusions: The red bull drinks with a (50 ml) had a positive effect on both surface hardness and roughness of zirconia restorations rather than a (50 ml) of coca-cola beverages.
