Purpose:
To evaluate the tooth discoloration effect of the daily use protocol of six different mouthrinses.
Methods:
70 extracted caries-free central incisors were divided into seven groups (n=10/per group) : Group 1: Curasept Anti Discoloration System; Group 2: CB12; Group 3: Listerine Zero; Group 4: Listerine Cool Mint; Group 5: Colgate Plax; Group 6: Kloroben. The teeth were exposed to the mouthrinse for 2 minutes daily for 3 weeks. Color measurement was performed four times: at the beginning of the study, and after 1, 2 and 3 weeks, with a digital spectrophotometer (Vita Easyshade Advanced). Color changes (ΔE) were calculated and ANOVA and post hoc Tukey's test were used for statistical analysis.
Results:
Although there was no statistically significant difference between the Colgate Plax and control groups, both groups had a significant difference from the other groups within all ΔE1, ΔE2 and ΔE3 values.
Clinical Significance:
Among the mouthrinses tested, Listerine Cool Mint group exhibited the most tooth discoloration, while Colgate Plax demonstrated the least noticeable color change.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Surface Tension and Surface Energy
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...
