Treatment of peri-implant mucositis using a glycine powder air-polishing or ultrasonic device: a randomized clinical trial

AIM: To evaluate the clinical treatment effects of a glycine powder air-polishing or ultrasonic device on peri-implant mucositis.

MATERIALS AND METHODS: Thirty-seven patients with one implant diagnosed with peri-implant mucositis (probing depth ≥4mm (0,2N) and bleeding on probing (BOP) (primary outcome)) were randomly assigned to treatment with either glycine powder air-polishing (GPAP) or ultrasonic (US) debridement. Treatment was performed at baseline and at 3 and 6 months. Professional supra gingival cleaning was performed at 9 and 12 months. Oral hygiene instructions were reinforced at each visit.

RESULTS: At 12 months there was a statistically significant reduction in mean plaque score, bleeding on probing and number of periodontal pockets >4 mm within the treatment groups compared to baseline. The percentages of diseased sites were significantly reduced for both groups.

CONCLUSIONS: Treatment with a glycine powder air-polishing or an ultrasonic device is effective in non-surgical treatment of peri-implant mucositis. This article is protected by copyright. All rights reserved.
