THE EFFECT OF AN ANTISEPTIC MOUTHRINSE ON IMPLANT MAINTENANCE: PLAQUE AND PERI-IMPLANT GINGIVAL TISSUES¹

Objective

To determine the effect of LISTERINE^® Antiseptic on plaque at the gingival/implant interface and on peri-implant gingivitis, when used as an adjunct to mechanical oral hygiene routines.

Methods

In this 3-month, randomized, double-blind, parallel, unsupervised, controlled clinical study, 20 healthy adult patients with at least two dental implants, a modified gingival index >1.5, and a Quigley-Hein plaque index >1.7 were enrolled. Patients received an oral prophylaxis and were assigned to rinse unsupervised with 20 ml of either LISTERINE^® Antiseptic or a 5% hydroalcohol control rinse for 30 seconds twice daily, in addition to their usual oral care routines. Patients were scored for the plaque index, gingival index, and bleeding index at baseline and at 1, 2, and 3 months.

Results

At 3 months, the LISTERINE^® Antiseptic group had statistically significant reductions in plaque index, gingival index, and bleeding index compared to the control group. There were no adverse events reported. The authors concluded that twice-daily rinsing with LISTERINE^® Antiseptic, used as an adjunct to routine mechanical oral hygiene, is effective in reducing plaque and improving the gingival health of peri-implant tissues.
