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 (nanohyid 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 artificial saliva Group 2 Coca–cola and artificial saliva Group 3 Rum and artificial saliva Group 4 Artificial 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 nanohyid composite resin and the results were statistically significant. When discoloration in different beverages was considered maximum discoloration took place in coca–cola>tea>rum>artificial saliva.Newer composites show lesser discoloration
