Background and objective: This study aimed to evaluate the effect of three types of bleaching
protocols on the surface roughness and compressive strength of composite resin.
Methods: Eighty composite resin samples were prepared using metal molds; forty samples (2
mm in height and 8 mm in diameter) for surface roughness evaluation and the other forty samples (6 mm in height and 4 mm in diameter) for compressive strength. Every forty samples
were divided into four groups; Group 1 (n = 10) The samples were stored in deionized water at
37°C for two weeks as control, group 2 (n =10) The samples were subjected to bleaching with
22% Carbamide Peroxide (CP) Home bleaching, group 3 (n =10) The samples were subjected to
bleaching with 14% Hydrogen Peroxide (HP) Home bleaching and group 4 (n =10) The samples
were subjected to bleaching with 25% Hydrogen Peroxide (HP in-Office) in a dental clinic. After
bleaching, groups 2, 3, and 4 were evaluated for surface roughness and compressive strength.
Results: The enamel surface roughness of all specimens were increased after bleaching protocols to a very similar extent with no statistically significant difference between the means of
enamel roughness of the control group and the other three groups and the highest value was
recorded in the Carbamide Peroxide group (CP), while compressive strength of the composite
was decreased after using bleaching protocols in all groups in comparision with the control
group and the least compressive strength was recorded in (HP) group followed by (HP in-Office)
group and (CP) group respectively.
Conclusion
Within the limitation of this study, the following conclusions can be withdrawn:
1. There was a decrease in surface roughness using different types of bleaching protocols (22% CP and 14% HP) at-Home
bleaching technique and (25%) in-Office
HP bleaching. Although there was no significant difference between them.
2. The compressive strength of the composite resin was reduced after bleaching with
no significant difference.
