Therapy of periodontitis by SRP and adjunctive use of powder air polishing - SRP and Erythritol

In both groups, the clinical variables PD, attachment level and BOP significantly improved three and six months after SI. The number of sites with PD = 5 mm was significantly lower in the test group than in the control group after six months. At six months versus baseline, there were significant reductions of Tannerella forsythia and Treponema denticola counts as well as lower levels of MMP-8 in the test group. Subgingival instrumentation with adjunctive erythritol air-polishing powder does not reduce BOP. But it may add beneficial effects like reducing the probing depth measured as number of residual periodontal pocket with PD = 5 mm when compared with subgingival instrumentation only.
