Efficacy of Glycine Powder Air-Polishing Combined With Scaling and Root Planing in the Treatment of Periodontitis and Halitosis

The aim of this clinical study was to evaluate the clinical efficacy of using perio flow adjunctively with mechanical instrumentation on periodontal parameters and halitosis. Sixty patients who presented with 4-6-mm probing pocket depth (PPD) were recruited for the study. Patients were randomly assigned to glycine powder air-polishing (GPAP) or control groups. For both groups PPDscores were recorded at the baseline and 1 month. Volatile sulphur compound (VSC) values were measured by a halimeter at the baseline, immediately after treatment, and at 7 days, 14 days and 1 month.
