Objective: This in vitro study aimed to evaluate the effectiveness of three different whitening mouthrinses on the color change and whiteness of stained teeth at different immersion times. Methods: Thirty-two human incisors teeth were stained in black tea solution for seven days and randomly divided into four groups, which were control (artifical saliva) and three whitening mouthrinses (containing tetrapotassium pyrophosphate, hydrogen peroxide, charcoal powder) (n=8). Spectrophotometric measurements were performed at baseline, after staining, after 12 hours, and 120 hours after keeping in whitening mouthrinses. The color changes and whiteness indexes occurring at different immersion times and after teeth staining were calculated. Results: The whitening mouthrinses tested showed similar changes in color change while exhibiting color change above the clinically acceptable threshold. Regarding whiteness index values, the highest value was obtained in the mouthrinse containing hydrogen peroxide with an immersion time of 120 hours (P < 0.05). While there was no significant difference in color change values at different immersion times, it was observed that the whiteness index values increased with increasing immersion time. Conclusion: Whitening mouthrinses can provide a clinically noticeable color change in discolored teeth. It can be said that using mouthrinses containing peroxide can provide more effective whitening on stained teeth.
