Abstract: Objective To study the clinical effect of two different therapeutic regimens on peri-implant mucositis. Methods A total of 24 implants which had developed peri-implant mucositis were randomly assigned to the test （13 implants） and control （11 implants） groups. Treatment of the test group consisted of mechanical scaling using carbon fiber scaler，blasted polishing，and the local application of minocycline hydrochloride，and the treatment of control group consisted of mechanical scaling and blasted polishing only. Results Both treatments were effective in reducing probing depth，modification sulcus bleeding index and plaque index. There was no significant difference between both groups. Conclusion Mechanical debridement and the control of plaque are effective in the treatment of peri-implant mucositis;supplemented application of minocycline hydrochloride can be beneficial to patient in 4 weeks.
