The classified as having RP (n 17) based on mean attachment loss (AL) and/or more than three sites AL ≥2.5 mm after scaling root planing, surgery, systemically administered amoxicillin metronidazole GRs 30) gain no treatment. Significant differences taxa among groups sought Kruskal-Wallis χ2 tests.Results: More detected patients disease (GR RP) without (PH). Subjects we...
