Correlations between salivary MPO activity and periodontal clinical parameters including (a) gingival bleeding index (GI), (b) bleeding on probing (BOP), (c) clinical attachment loss (CAL) index scores, and (d) pocket depth (PD) index scores. PD index score in each individual = [(1 × number of sites with PD score 1) + (2 × number of sites with PD score 2) + (3 × number of sites with PD score 3)]/total measured PD sites. CAL index score in each individual = [(1 × number of sites with CAL score 1) + (2 × number of sites with CAL score 2) + (3 × number of sites with CAL score 3)]/total measured CAL sites.
