Objective This aim of this study was to evaluate a chitosan brush for the treatment of peri‐implant mucositis. Materials and methods A total of 11 patients with a combined total of 24 dental implants and who were diagnosed with peri‐implant mucositis were included in this 6‐month, split mouth, pilot clinical trial. Implants were randomly assigned to either treatment with a chitosan brush using an oscillating dental hand piece or treatment with titanium curettes. Supportive treatment was provided at 3 months. Two calibrated periodontists, blinded to treatment group, performed all examinations, including probing pocket depths (PPD) and bleeding on probing (mBoP). The changes in clinical parameters were compared between groups at 2 weeks, 4 weeks and 6 months. A Mann‐Whitney U test with an alpha level of 0.05 was used for the statistical analyses. Results Both groups demonstrated significant reductions in mBoP between baseline and 6 months. The test implants treated with the chitosan brush had a better improvement in mBoP at 2 weeks and 4 weeks compared to the implants treated with the titanium curettes. The reduction in PPD was significantly better in the test group at 4 weeks. All implants had stable bone levels, as seen on radiographs between baseline and 6 months. Conclusion Reduced signs of inflammation were seen in both groups 6 months after the baseline treatment and 3 months after maintenance. A chitosan brush seems to be a safe and efficient device for debridement of dental implants.
