The Effect of Bleaching Agent Application on the Color Change of Fiber-Reinforced Composites
Journal Title: Modern Approaches in Dentistry and Oral Health Care - Year 2018, Vol 3, Issue 1
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<0,05). The fiber group had lower delta e values. Color change after bleaching was less in the fiber group (p = 0,001). Fiber addition had negatively affected the penetration and activity of the bleaching agent on posterior composite. Home bleaching agent was affected both anterior and posterior composite. It should be informed that the bleaching procedures are effect of external colorings, but composite fillings cannot appear as white as natural teeth after bleaching.
