To compare the surface hardness of two resin composites Esthet_X and filtek supreme after exposure to three different staining agents coffee, tea and red wine and two different dentist prescribed at home bleaching agents colgate platinum & opalescence and one over the counter bleaching agent (Colgate Platinum).
60 specimens, 9mm×2mm each of Filtek Supreme and Esthet-X were prepared. The 60 specimens were divided into 4 groups:
Group 1: coffee group
Group 2: tea group
Group 3: red wine group
Group 4: control group (distilled water)
The results showed that in case of Filtek Supreme a statistically significant difference in surface hardness was noted when subjected to coffee and tea and the tea group when subjected to OTC bleaching agent. In case of Esthet-X, significant difference in surface hardness was observed when subjected to tea and the same tea group when treated with Opalescence 20%.
