Abstract

Background/purpose: This randomized clinical trial was aimed at comparing two different means of delivering chlorhexidine digluconate (CHX) for plaque control during the 2 weeks following implant surgery. Materials and Methods: Twenty patients selected for implant therapy were randomly divided into two groups: 10 subjects used 15 ml of 0.12% CHX mouthrinse (control group) and 10 used 0.2% CHX spray (test group). Professional oral hygiene was carried out immediately before surgery. During the 14 days following surgery mechanical oral hygiene was performed only at the teeth not surgically involved. Plaque index (PI), stain index (SI), modified gingival index and taste alteration were assessed on the 7th and 14th day after surgery. The clinical parameters were evaluated at four tooth surfaces by a single examiner. Teeth proximal to surgical site and teeth not involved were statistically compared. Results: In both groups, the PI increased similarly, with respect to the baseline, at days 7 and 14. There was no significant difference between the two groups at either time point. On the contrary, in the control group, the SI increased significantly when compared with baseline over the 14 days both at teeth nearest to surgical sites and at not-involved sites. In the test group pigmentation was consistent only at teeth proximal to the surgical site. When considering not-involved sites, tooth staining was significantly lower in the test with respect to the control group. Conclusions: The present study indicates that the efficacy of CHX spray in the post-surgical control of dental plaque is similar to that of CHX mouthwash. Tooth staining, however, is significantly lower in the spray group at sites not surgically involved. These effects might be related to the route of CHX delivery, as well as the total dose administered that was significantly lower in the spray group with respect to the rinse group.
