Background/Aim. Periodontal tissue maintenance therapy
is an important phase of the overall periodontal disease
therapy. This paper aims to determine subgingival airpolishing efficacy with glycine powder in putative paropathogens reduction, plaque index, gingival bleeding index and
probing depth. Methods. The study included 44 patients
with aggressive periodontitis of both sexes, aged between 21
and 50, divided into two groups. Subgingival air-polishing
was applied in the first group and sonic scaling in the control (second) group. Biofilm samples were taken from 5
deepest periodontal pockets before the therapy and 3 and
15 months after it. Paropathogens Aggreggatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsithya,
Prevotella intermedia, Treponema denticola were detected by PCR
analysis. Results. Paropathogens values were decreased after applied treatments. There was a statistically significant
reduction in the mean value of full-mouth plaque (FMPS),
from 43.00 to 14.90 (first group) and from 44.71 to 15.54
(second group), full-mouth bleeding score (FMBS) from
42.55 to 13.85 (first group) and from 43.04 to 15.17 (second
group), as well as in probing depth from 3.40 to 2.64 (first
group) and from 3.85 to 2.91 (second group), three months
after the therapy. Conclusion. Subgingival air-polishing
successfully reduces putative paropathogens and clinical parameters three months after the treatment.
