Average of periodontal sites colonized (prevalence) by the new pathogens evaluated for the treatment group SRP or SRP+MTZ+AMX at baseline, after 3 months and 1 year. Comparison between treatment groups after 1 year. SRP – Scaling root planing; MTZ – Metronidazole; AMX – Amoxicillin. The statistical significance of differences between groups was assessed using the Mann-Whitney or Friedman test (p < 0.05). (* in black) indicates statistical significance adjusted for multiple comparisons; (* in red) indicates unadjusted statistical significance.
