represents differences (value at follow-up minus value at baseline). Pearson’s correlation coefficients. N: number; SD: standard deviation; PPD: probing pocket depth; CAL: clinical attachment level; BOP: bleeding on probing; PCR: plaque control record; ROM: reactive oxygen metabolites; CARR U: Carratelli units; and BAP: biologic antioxidant potential. |
