Periodontal index of all study participants
| Parameter | Experimental group (before treatment) | Experimental group (after treatment) | Control group |
|---|---|---|---|
| PD (mm; mean ± SD) | 5.2 ± 0.7a | 2.2 ± 0.7b | 5.3 ± 0.6 |
| CAL (mm; mean ± SD) | 4.7 ± 0.5a | 3.3 ± 0.5b | 4.6 ± 0.5 |
| BOP (% site; mean ± SD) | 2.5 ± 4.8a | 0b | 2.3 ± 4.9 |
| SUP (% site; mean ± SD) | 2.0 ± 2.9a | 0b | 2.1 ± 3.4 |
a
Every parameter had no significant difference between the experimental group (before treatment) and control group by t‐test (p > 0.05).
b
Every parameter had significant difference between the experimental group (after treatment) and control or experimental group (before treatment) by t‐test (p < 0.05).
Abbreviations: BOP, bleeding on probing; CAL, clinical attachment level; PD, probing depth; SUP, suppuration.
