Özet
Background This in-vitro study aimed to assess the effects of whitening toothpastes on color and translucency changes and surface roughness of resin composites. Methods Disk-shaped resin composite samples from each composite (Clearfil Majesty Esthetic, Palfique Estelite Paste, and Charisma Smart) were made and randomly allocated into five groups (n = 10): Crest Pro Health Whitening, Advance White Pro, Sensodyne Extra Whitening, a control group (distilled water), and a positive control group (exposed to only stain). The samples were exposed to a tea solution and brushed for 30 days. Surface roughness and color measurements were performed immediately and at 15 and 30 days. Data were evaluated using three-way ANOVA (alpha = 0.05). Results Significant differences were determined among the groups for Delta L, Delta b, and Delta E-00 values in each resin composite (p < 0.05). The positive control group presented considerably higher Delta L values than the other groups (p < 0.05). Color changes presented no significant difference among whitening toothpastes. The color change in all groups was above the clinically acceptable level (triangle E-00 > 1.8) after 30 days, except for the distilled water. Translucency changes remained below the clinically perceptible threshold (Delta RTP00 < 0.62) in most groups. For samples brushed with whitening toothpastes, Delta b had the greatest impact on Delta E-00, whereas in the distilled water and positive control groups, Delta L was the primary factor influencing Delta E-00 changes. The surface roughness of the resin composites increased significantly over time (p < 0.001). Clearfil Majesty Esthetic showed the highest surface roughness above clinically acceptable limits (Ra > 0.2 mu m), regardless of the whitening toothpaste used. Roughness values did not show significant differences among the toothpastes for each resin composite. Conclusions Whitening toothpaste with blue covarine did not create a different color change. All whitening toothpastes tested increased the surface roughness, regardless of the type of resin composites evaluated. The type of resin composite had a minimal impact on color and translucency changes when exposed to brushing with various whitening toothpastes.
