“…The ΔE values demonstrate that if there is a color change between the two time periods, some authors [7] only consider the color change visually detectable when the ΔE is greater than 3.7, the threshold value of ΔE that was adopted in this study. By observing the samples' mean values of ΔE, it was verified that the LW group showed the highest color variation and differed from the other groups subjected to immersion in mouth rinses as well as from the control group, which did not present a clinically significant change (ΔE < 3.7) [7,20]; but the groups treated with other mouth rinses also presented significant color variation similar to one another and different than the LW and CG groups. This result corroborates previous studies [2,8] and the results obtained by Torres et al [4], which demonstrated color changes promoted in tooth enamel by Listerine Whitening and Colgate Plax Whitening similar to conventional bleaching with 10% carbamide peroxide gel.…”

“…Mouth rinses are also OTC products and are essentially composed of water, antimicrobials, a coloring agent, and salts [5]; sometimes alcohol is used as solubilizer and preservative [7,8], and hydrogen peroxide or a bleaching agent [2,5,6,8] is used in concentrations of approximately 3% to 6% [1]. It is known that some mouth rinses showed efficacy when used as bleaching agents as described by Torres et al [4] and Lima et al [2]; however, the daily contact of such products for a long period of time without professional supervision can promote changes in the surface of the tooth enamel.…”

This study aims to evaluate the effect of mouth rinses on the color, microhardness, and surface roughness of tooth enamel. Sixty dental blocks were collected from human third molars and divided in five groups (n = 12): the control group (CG) without immersion in mouth rinse, Listerine Zero, Colgate Plax Fresh Mint, Listerine Whitening, and Colgate Luminous White. The groups were subjected to initial color analysis; the microhardness and roughness of the enamel surfaces were evaluated. Next, the samples were subjected to immersion in mouth rinses or brushing with conventional fluoride toothpaste (CG) according to the manufacturer's instructions; after a 12-week treatment, the color, microhardness, and roughness were once again assessed and compared with the initial analysis. Data were tabulated and analyzed through a two-way analysis of variance (ANOVA) (color and roughness) followed by Tukey's test. Microhardness was analyzed through the Kruskal-Wallis test followed by Dunn's test; the level of significance was 5%. All groups immersed in mouth rinses had a higher level of microhardness loss than CG; additionally, all groups showed changes in the enamel surface. Enamel surface loss was observed using a roughness test, and the mouth rinses promoted a higher level of color changes than CG. Given the results, it can be concluded that the mouth rinses led to significant changes in tooth enamel.

“…1 The Commission Internationale de l'Eclairage (CIE) color system 6 is widely used for the analysis of color differences. 4,7,8 According to this system, a particular shade in the color space is defined by three coordinates: L*, a*, and b*. L* represents the luminosity axis (lightness, ranging from black to white), a* represents the green-red axis (ranging from green to red), and b* represents the blue-yellow axis (ranging from blue to yellow).With this system, a color difference between two objects can be calculated and can be expressed in units (CIELAB ΔEab*) that can be related to clinical acceptance.…”
