Adjunctive glycine powder air-polishing for the treatment of peri-implant mucositis: an observational clinical trial

ObjectivesThe aim of this study was to make a comparative evaluation of professional oral hygiene with or without the adjunct of glycine air-powder system for the treatment of peri-implant mucositis.
MethodsAfter the application of inclusion and exclusion criteria, patients were divided in two groups: in control group, patients were treated with professional oral hygiene manoeuvres (POH) while in the test group, glycine air-powder system (SGA) was adjuncted to professional oral hygiene. Probing depth (PD), bleeding index (BI) and plaque index (PI) were measured at baseline, and 3 and 6months after the treatment.
ResultsA total of 30 patients (15 per group) were selected for the study. In POH e SGA group, PD was, 2.860.37 and 3.00 +/- 0.36mm at baseline, 2.90 +/- 0.53 and 2.62 +/- 0.50mm after 3months, 2.96 +/- 0.56 and 2.41 +/- 0.54mm after 6months, respectively, significantly lower in SGA group in the last follow-up visit. In both groups, both PI and BI decreased over time.
ConclusionsThe present reports showed that both techniques were useful for the treatment of peri-implant mucositis. In the test group (with glycine powder), a significant reduction of probing depth was observed.
