Thirty-seven sites with probing depth (PD) of 5-7 mm and BANA positive in 6 patients with chronic periodontal disease were selected. Sites were assigned to different treatment groups consisting of SRP only (group 1), SRP + irrigation with collagen gel (group 2), or SRP + irrigation with collagen gel containing 1% chlorhexidine (group 3). Subgingival irrigation was performed after initial SRP and at 7, 14 and 21 days. Clinical measurements including PD, plaque index (PI), gingival index (GI), gingival recession (GI), bleeding on probing (BOP) and clinical attachment level (CAL) were performed at the selected sites at baseline, 60 and 90 days and the BANA test was performed on plaque samples from the same sites at baseline and 90 days. There was an improvement in clinical parameters in all groups with a significantly greater decrease in GI and bleeding in the chlorhexidine group. There was a greater reduction of BANA positive sites in groups 2 and 3. The authors concluded that 1% chlorhexidine collagen gel is a promising adjunct to SRP in the treatment of adult periodontitis.209-213engchlorhexidinecollagenn benzoylarginine 2 naphthylamidetopical antiinfective agentadultanalysis of variancechi square distributionclinical trialcontrolled clinical trialcontrolled studyfemalegelgingiva diseasehumanlavagemalemiddle agednonparametric testperiodonticsperiodontitispreventive dentistrytooth plaquetreatment outcomeAdultAnalysis of VarianceAnti-Infective Agents, LocalBenzoylarginine-2-NaphthylamideChi-Square DistributionChlorhexidineCollagenDental Plaque IndexDental ScalingFemaleGelsGingival RecessionHumansIrrigationMaleMiddle AgedPeriodontal IndexPeriodontal PocketStatistics, NonparametricTreatment OutcomeArtigoAcesso aberto2-s2.0-00352329222-s2.0-0035232922.pdf61008594658719293534044399884035
