Self-perceived oral odor (mean ± sd) of participants of Study B before and after the use of the oral rinse in relation to the extent to which the participants reported taking into account one’s oral odor

|---|---|---|---|---|
| Mean ± sd | n (%)*** | Mean ± sd | n (%)*** | |
| “Never” | 73.7 ± 16.3 | 59 (20.3) | 85.0 ± 7.1 | 10 (20.0) |
| “Almost never” | 71.2 ± 9.0 | 24 (8.2) | 75.0 ± 10.7 | 8 (16.0) |
| “Sometimes” | 64.9 ± 17.6 | 55 (18.9) | 77.1 ± 9.8 | 17 (34.0) |
| “Often” | 69.0 ± 12.1 | 42 (14.4) | 82.0 ± 14.8 | 10 (20.0) |
| “Always” | 72.9 ± 18.6 | 111 (38.1) | 64.0 ± 20.7 | 5 (10.0) |

*p < 0.05: mean scores before the use of oral rinse were compared using a one-way ANOVA, between group differences based on post hoc tests (LSD). **p < 0.05: Total pre- and posttest (oral odor) scores were compared using a paired t-test. ***p < 0.05: Differences in the extent to which participants take into account their oral odor, before and after oral rinse, using the Wilcoxon signed rank test
