Effect of root planing on pooled GCF sample volume
| Site category | Pretreatment volume (28 hr) | Post-treatment volume (196 hr*) |
|---|---|---|
| Untreated control | 2.38 ± 0.36 μL | 1.78 ± 0.22 μL |
| Root-planed | 2.05 ± 0.19 μL | 1.49 ± 0.22 μL |
Results are presented as mean ± SEM.
Post-treatment levels were adjusted for pretreatment levels, using ANCOVA. The difference between the mean post-treatment volumes was not significant (P = 0.412).
