This randomized controlled clinical trial investigates the effectiveness of trehalose powder compared to glycine powder when used in air-polishing during supportive therapy for peri-implant mucositis, a reversible inflammatory condition affecting the soft tissues around dental implants. A total of 40 adult patients with peri-implant mucositis will be enrolled and randomly assigned to receive non-surgical periodontal therapy combined with air-polishing using either trehalose powder (test group) or glycine powder (control group). Clinical parameters will be evaluated at baseline, 1 month, 3 months, and 6 months. These include Plaque Index (PI), Bleeding on Probing (BoP), Probing Pocket Depth (PPD), and Bleeding Score (BS), in order to assess plaque accumulation, inflammation, and bleeding. The primary objective is to compare the reduction in plaque levels between the two groups over the study period. Secondary outcomes include evaluation of changes in gingival inflammation and probing depths, as well as assessment of implant surface integrity through in vitro scanning electron microscopy (SEM) after treatment. The aim of the study is to determine whether trehalose powder offers improved clinical outcomes and greater implant surface preservation compared to glycine powder in the non-surgical management of peri-implant mucositis.
