Descriptive analysis of bleeding on probing (BOP), pocket depth (PD), and salivary levels of hemoglobin (Hb) and lactate dehydrogenase (LD) against Community Periodontal Index (CPI) criteria

| LD | 346.58 ± 306.73 | 163.75 ± 64.99 | 247.75 ± 109.66 | 376.90 ± 360.77 | 544.17 ± 358.74 | <0.001 |
| (IU/L) | 279.00 (128.75–410.50) | 157.50 (111.00–212.25) | 233.50 (192.00–3111.75) | 30800 (177.00–412.00) | 451.50 (229.50–694.75) |
Data are expressed as mean ± standard deviation and median (25 %, 75 % percentiles). Dose response relations were observed except for CPI 1 of the BOP% and Hb and for CPI 0 of LD. All differences were statistically significant (Kruskal-Wallis test)
