CHX: SRP + chlorhexidine rinsing group. S1: Periodontitis stage 1; S2: Periodontitis stage 2; S3: Periodontitis stage 3; S4: Periodontitis stage 4. Data are expressed as median (minimum–maximum). * p < 0.05; comparison between the evaluation at baseline and at one and 6 months in the same group; ° p < 0.05; comparison between groups at the same evaluation time.
