Abstract EN
Background and Aim: The purpose of this study was to evaluate the effect of carbamide peroxide 20% on microhardness of nanocmposites and nanohybrid composites.
Materials and Methods: 60 cylindrical discs of 3 nanocomposite and nanohybrid composite resins were fabricated.
(Grandio/ Voco , Filtek z350 /3M ESPE, vitra/ FGM), 20 specimens of each (n=20), Each group was divided into 2 subgroups (n=10) (carbamide peroxide 20% , control group).
The specimens of the first group were immersed in carbamide peroxide 20% for 4 hours daily.
While the second group were stored in distilled water.
After 14 days, microhardness was calculated using GALILEO MICROSCAN OD.
Results were statistically analyzed by one-way ANOVA, Bonferroni, and T-tests at significance level of (p<0.05).
Results: No significant differences in microhardness were observed between carbamide peroxide 20% and control group in FGM and 3M (p>0.05).
However, a significant increase in microhardness was detected in carbamide peroxide 20% compared to control group in VOCO.
When composite resins were compared, statistically significant differences in microhardness were observed in both carbamide peroxide 20% and control group (p<0.05).
Conclusion: The effect of carbamide peroxide 20% on composite resins was material dependent.
Microhardness of FGM and 3M was not affected, while VOCO showed an increase in microhardness after bleaching.
