VELASCO, Fernanda Guerra et al. Clinical evaluation of subgingival application of a triclosan gel in the treatment of periodontal furcation defects. IJD, Int. j. dent. [online]. 2010, vol.9, n.3, pp. 136-141. ISSN 1806-146X.

The aim of this study was to evaluate the effectiveness of subgingival irrigation with a gel of triclosan - polydimethylsiloxane 1% as to mechanical instrumentation in periodontal furcation defects. Thirty patients presenting probing depht of > 4mm and furcation involvement on the buccal surfaces of molars were randomly assigned to receive either scaling and root planning plus a triclosan gel (test group) or scaling and root planning plus a placebo gel (control group). Following oral hygiene instructions and scaling and root planing, the test group received the application of triclosan gel 1% once a week for four weeks and the control group received a placebo gel for the same period. Clinical parameters evaluated at baseline, 45 and 90 days were: plaque index (IP), bleeding on probing (SS), probing depth (PS), vertical clinical attachment level (NIC-V) and horizontal clinical attachment level (NIC-H). The results showed that after 45 and 90 days of the gels application, there were improvements in the following clinical parameters: PS, NIC-V, SS and IP, when compared to the baseline. No statistically significant improvement was found in NIC-H for any group. Intergroup comparisons showed no statistically significant differences regarding any of the clinical parameters analyzed. Within the limits of this study, it was concluded that repeated subgingival irrigations with a triclosan gel, as an adjunct to mechanical therapy, may not provide additional benefits in the treatment furcation defects.
