Effect of Alcoholic and Non Alcoholic Beverages on colour stability of composition Resin – an in vitro Study

Abstract

Resin composites are widely used because they have excellent aesthetic properties and can be bonded to dentin and enamel. This study aims to determine the colour stability of composite resins (nanohybrid composite and giomer.) after their exposure to commonly consumed beverages namely tea, coca-cola and alcoholic beverages. Methods and Material: A total of 80 composite resin specimens were made in the form of disks and were immersed in beverages divided into four groups. Group 1 Test solution tea and articial saliva Group 2 Coca-cola and articial saliva Group 3 Rum and articial saliva Group 4 Articial saliva (control group). The colour change was assessed at the intervals of 24hrs, 15th day and 30th day of immersion with the help spectrophotometer. Results: When discoloration of two resins composite was considered the overall maximum discoloration took place in giomer as compared to nanohybrid composite resin and the results were statistically signicant. When discoloration in different beverages was considered maximum discoloration took place in coca-cola>tea>rum>articial saliva.Newer composites show lesser discoloration
