*p<0.05 (before and after treatment in the same group).

**p<0.05 (comparison between the groups before treatment).

PT  =  periodontal treatment; BOP  =  bleeding on probing; PPD  =  probing pocket depth; CAL  =  clinical attachment level; GI Score¹  =  clinically quantifies gingival inflammation: 0  =  absence, 1  =  little, 2  =  moderate, 3  =  severe; PI Score²  =  quantifies the presence of bacterial plaque on the tooth: 0  =  absence, 1  =  little, 2  =  moderate, 3  =  severe; PPD ≥ 5 mm  =  probing pocket depth ≥ 5 mm; SD  =  standard deviation; n  =  number.
