Abstract: Background: The aim of this clinical trial was to compare the outcome of non-surgical treatment of interproximal and non-interproximal Class 11 furcation involvements. Methods: Thirty-eight patients presenting at least one Class 11 furcation involvement that bled on probing with a probing depth (PD) >= 5 mm were recruited. Furcation involvements were grouped as either buccal and lingual furcation involvements (BLFI) or interproximal furcation involvements (IFI). The following clinical outcomes were evaluated: visible plaque index, bleeding on probing (BOP), position of the gingival margin, relative attachment level (RAL), PD, and relative horizontal attachment level (RHAL). N-benzoyl-L-arginine-p-nitroanilide (BAPNA) testing was used to analyze trypsin-like activity in dental biofilm. All parameters were evaluated at baseline and 1, 3, and 6 months after non-surgical subgingival instrumentation. Results: Six months after treatment, both groups had similar means of RAL and RHAL gain (P > 0.05). These variables were 1.22 and 1.07 mm in the IFI group and 1.38 and 1.20 mm in the BLFI group, respectively. The PD reduction was significantly greater in the BLFI group than in the IFI group (2.59 and 2.11 mm, respectively; P < 0.05). The BLFI group presented fewer sites with PD >= 5 mm than the IFI group at all post-treatment periods. At 6 months, the BAPNA test showed that only the BLFI group had values significantly different from baseline. This means that the BLFI group had significantly lower BAPNA values compared to the IFI group at 6 months. Conclusion: Buccal and lingual Class 11 furcation involvements respond better to non-surgical therapy compared to interproximal Class 11 furcation involvements.
