INTRODUCTION: The purpose of this study is to investigate the effects of three whitening mouthwashes with different contents on hybrid ceramics with three separate surface treatments in terms of color change.
METHODS: Samples of 7x5x1 mm dimensions were prepared from hybrid ceramic blocks (Vita Enamic- VE). The surfaces of the samples were standardized with silicon carbide papers. The samples were randomly divided into 3 groups (Group C: no additional polishing, Group L: VE technical kit and Group G: glaze was applied) (n=24). All samples were kept in coffee for seven days after the initial colors were recorded. Following the second color measurement (ΔE001), each group was divided into 3 subgroups and kept in whitening mouthwashes with different contents (Containing hydrogen peroxide, non-hydrogen peroxide and activated carbon) for 24 hours (n=8). The final color measurement was measured (ΔE002). Color changes were evaluated according to CIEDE2000. Shapiro-Wilk, One way ANOVA and post hoc Tukey tests were used for statistical analysis of the data (p˂0.05).
RESULTS: There was a significant difference in all groups for ΔE001, with the highest in Group C (Group L and Group G, respectively). The mouthwashes showed similar color changes on VE with different surface treatments (p≥ 0.05). Group C showed a significantly higher ΔE002 value than Group G in containing hydrogen peroxide mouthwash.
DISCUSSION AND CONCLUSION: Clinically acceptable color changes were observed in groups G and L after kept in coffee. After immersion in whitening mouthwash, all groups showed values below the threshold of perceptibility and acceptability (50: 50% acceptability ΔE= 1.8, perceptibility ΔE=0.8).
