Abstract

The aim of this study was to investigate the effect of a home-belaching (16% carbamide pereoxide) agent on color change in aged anterior / posterior composite samples with or without fiber reinforcement. Two different composites, one anterior and one posterior, a home bleaching agent and polyethylene fiber were used. All samples were prepared with 8 mm wide and 4 mm high teflon molds. Polyethylene fiber was incorporated in the middle of the samples in fiber groups. The samples were kept in distilled water for a total of 14 days, inıtial color measurements were made. After aging, bleaching agent was applied for 14 hours daily for 4 hours. Color measurements were repeated. Data were statically analyzed by using One-way ANOVA and t-test. Anterior composites’ delta e values after bleaching were not statistically significant between fiber group and control group without fiber (p>0,05). Posterior composites’ delta e values after bleaching were statistically significant between fiber group and control group without fiber (p
