Comparison between groups according to the gingival index at buccal and lingual aspects.
| Gingival index (GI) | |||||
|---|---|---|---|---|---|
| Groups | Time | ||||
| W −1 (mean ± SD) | W0 (mean ± SD) | W1 (mean ± SD) | W12 (mean ± SD) | W18 (mean ± SD) | |
| CT | 0.12 ± 0.16 | 0.59 ± 0.49∗ | 0.07 ± 0.10 | 0.12 ± 0.12 | 0.12 ± 0.12 |
| BM | 0.08 ± 0.14 | 0.62 ± 0.51∗ | 0.07 ± 0.12 | 0.13 ± 0.13 | 0.06 ± 0.07 |
W −1: preclinical trial; W0: established gingivitis; W1: 1st evaluation after brushing for 1 week; W12: evaluation of brushing for 12 weeks; W18: evaluation of brushing for 18 weeks. For each group, ∗indicates significant difference between the times based on Tukey's test.
