In test group B, which received the cymenol mouthwash in phase 2, there were statistically significant differences in the percentages of the visible plaque area between day 0 (5.68 ± 3.53%) vs. day 4 (i.e., after the placebo mouthwash: 46.57 ± 18.92%, p < 0.001) and day 8 (i.e., after the cymenol mouthwash; 65.12 ± 16.37%, p < 0.001).Table
