Streptococcus mutans adhesion for the PUL, PUC, PUZ, and PET groups at the baseline and after repeated toothbrushing (n = 5).
| Group | Baseline | After repeated toothbrushing | ||||||
|---|---|---|---|---|---|---|---|---|
| Mean | S.D. | Median | Min–max | Mean | S.D. | Median | Min–max | |
| PUL | 1.59a | 0.28 | 1.66 | 1.21–1.96 | 1.48 | 0.33 | 1.37 | 1.26–2.06 |
| PUC | 1.03b | 0.16 | 1.02 | 0.83–1.22 | 0.90 | 0.32 | 0.88 | 0.60–1.39 |
| PUZ | 1.46ab | 0.35 | 1.37 | 1.19–2.06 | 1.41 | 0.39 | 1.24 | 1.12–2.06 |
| PET | 1.25ab | 0.28 | 1.39 | 0.88–1.52 | 1.37 | 0.21 | 1.4 | 1.09–1.57 |
| Significance | * | * | ||||||
Statistical significance at baseline was assessed using one-way ANOVA with Tukey’s post hoc test. After repeated toothbrushing, the Kruskal–Wallis test with Mann–Whitney U tests and Bonferroni correction was used for post hoc comparisons. Superscript letters (a, b, c) indicate results of post hoc comparisons; groups sharing the same letter are not significantly different (p > 0.05). *p < 0.05.
