Figure 4

Plots of the mean changes in individual full-mouth mean clinical attachment level between baseline and 6 months post-SRP of subjects in the three treatment groups. Subjects in the SRP and SRP+PPC groups rinsed with placebo. The circles represent the mean value of each subject. The dashed line represents the median of change of this clinical parameter in all 60 subjects. Positive values represent a gain in clinical attachment level (CAL), while negative values represent a loss in CAL at 6 months post-SRP. SRP: Scaling and root planing; PPC: Professional plaque control; CHX: Chlorhexidine rinsing.
