used for the studied toothpastes.
After the first phase of the study (using a different toothpaste for each side
for 30 days with a washout period of 7 days), participants returned to the
dental office. They received another device to start a new washout period of 7
days. They also received two new tubes of different toothpastes for the second
phase for 30 days. The devices were collected after the second phase, and the
fragments were detached. New color, gloss, microhardness, and roughness
measurements were performed according to the methodology previously
described.The data were normally distributed for color, surface roughness, gloss, and
microhardness (Kolmogorov Smirnov test, p<0.05). Thus, the One-way ANOVA test
was performed with the Geisser-Greenhouse correction, with a level of
significance of 95%, followed by the post hoc Tukey's test. The WI
