RESUMO
The aim of this randomized single-blind controlled clinical trial was to evaluate the effect of topically applied povidone-iodine (PVP-I), used as an adjunct to non-surgical therapy of furcation involvements. Forty-four patients presenting at least one class II furcation involvement that bled on probing, in bucal or lingual surfaces, with probing pocket depth ³ 5 mm were recruited. Patients were stratified into 2 treatment groups: subgingival instrumentation by an ultrasonic device using PVP-I (10%) as the cooling liquid (test group); identical treatment using distilled water as the cooling liquid (control group). The following clinical outcomes were evaluated: plaque index, bleeding on probing (BOP), position of the gingival margin, relative attachment level (RAL), probing pocket depth (PPD) and relative horizontal attachment level (RHAL). BAPNA test was used to analysis the trypsin-like activity in dental biofilm. The clinical and biochemical parameters were evaluated at baseline and 1, 3 and 6 months after therapy. Both groups had similar means of PPD reduction and RAL and RHAL gain. At 6 months, these variables were, respectively, 2.31 mm, 1.17 mm and 1.00 mm in the control group and 2.31 mm, 1.23 mm and 1.02 mm in the test group (p<0.05). No differences were observed in terms of the frequency distribution of sites demonstrating RAL gain ³ 2 mm. The comparison between groups on BOP of the furcation sites, at 6 months and on the number of sites referred for re-treatment at 3 months showed better values in the test group (p=0.06). The results of BAPNA test failed to demonstrate significant differences between groups. The use of topically applied PVP-I with subgingival instrumentation may provide additional clinical significant benefits to the treatment of class II furcation involvements
