DenTiUS Deep Plaque clinical indices were obtained in test groups A and B in phase 1 (after using the cymenol and placebo mouthwashes, respectively) and phase 2 (after using the cymenol mouthwash in both groups)

SD, standard deviation

*Due to the non-normal distribution of some of the contrasted variables, the Mann-Whitney U test was applied to compare the two groups
