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

Objectives: The 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. Methods: After 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 6 months after the treatment. Results: A total of 30 patients (15 per group) were selected for the study. In POH e SGA group, PD was, 2.86 ± 0.37 and 3.00 ± 0.36 mm at baseline, 2.90 ± 0.53 and 2.62 ± 0.50 mm after 3 months, 2.96 ± 0.56 and 2.41 ± 0.54 mm after 6 months, respectively, significantly lower in SGA group in the last follow-up visit. In both groups, both PI and BI decreased over time. Conclusions: The 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.
