Figure 3.

The treatment effects of the periodontal anti-infective treatment on the recorded clinical periodontal parameters in 13 patients with periodontitis: (A) bleeding on probing (%), (B) visible plaque index (%), (C) mean of PPD (mm), (D) mean of CAL (mm), and (E) the number of at least 4 mm periodontal pockets. The patients were examined at base level t0 and at 1st recall visit t1 (6 weeks). The differences in the clinical parameters between t0 and t1 were tested with a paired-samples t-test (2-sided): (A) p < 0.001, (B) p = 0.006, (C) p < 0.001, (D) p < 0.001, and (E) p < 0.001. Circle (o) represents outliers of between 1.5 and 3 times the interquartile range.
