Comparison of mean percentage changes in various parameters in SRP-P and SRP-S groups.
| Percentage | Group | P value | |||
|---|---|---|---|---|---|
| SRP-P | SRP-S | ||||
| Mean | SD | Mean | SD | ||
| Salivary MDA | 32.35 | 15.38 | 45.71 | 11.08 | .017* |
| Serum MDA | 18.65 | 27.48 | 17.91 | 20.22 | .004** |
| GI | 20.66 | 29.90 | 38.69 | 14.62 | <.001** |
| BOP | 23.36 | 12.76 | 50.24 | 12.83 | <.001** |
| PPD (mm) | 6.66 | 15.94 | 39.85 | 9.01 | <.001** |
| CAL (mm) | 7.46 | 12.61 | 31.53 | 8.95 | <.001** |
BOP = bleeding on probing, CAL = clinical attachment loss, GI = gingival index, MDA = malondialdehyde, PPD = probing pocket depth, SD = standard deviation, SRP-P = scaling root planning with placebo, SRP-S = scaling root planning with spirulina.
P < .05 is statistically significant.
