Abstract EN
Background : the compressive strength of composite resin may be affected by bleaching agent.
This study was conducted to evaluate the effect of two different bleaching agents; at home (22 % carbamide peroxide) and in Office ; light activated (35 % hydrogen peroxide) bleaching agent on the compressive strength of light cured composite resin; spectrum (submicron hybrid composite).
Material and methods : A total number of 20 samples were prepared, 10 samples for each type of bleaching agent which were divided in to 2 groups ; first group was subjected to at-home bleaching for one day.
The second group was subjected to at-home bleaching for one week, The third group was subjected to the in-office (35 % H2O2) for one day.
The forth group was subjected to in-office bleaching for three days.
Results : there were statistically significant differences between the tested groups (p=0.048).
Highly significant reduction of the compressive strength of composite was observed subsequent to treatment with H2O2 for three times.
Conclusion : Reduced compressive strength was detected in composite when it was subjected to bleaching process with H2O2 carbamide peroxide.
