Effects of triclosan on host response and microbial biomarkers during experimental gingivitis
AimThis exploratory randomized, controlled clinical trial sought to evaluate antiâinflammatory and âmicrobial effects of triclosan during experimental gingivitis as assessed by host response biomarkers and biofilm microbial pathogens.Materials and MethodsThirty participants were randomized to triclosan or control dentifrice groups who ceased homecare for 21Â days in an experimental gingivitis (EG) protocol. Plaque and gingival indices and saliva, plaque, and gingival crevicular fluid (GCF) were assessed/collected at days 0, 14, 21 and 35. Levels and proportions of 40 bacterial species from plaque samples were determined using checkerboard DNAâDNA hybridization. Ten biomarkers associated with inflammation, matrix degradation, and host protection were measured from GCF and saliva and analysed using a multiplex array. Participants were stratified as âhighâ or âlowâ responders based on gingival index and GCF biomarkers and bacterial biofilm were combined to generate receiver operating characteristic curves and predict gingivitis susceptibility.ResultsNo differences in mean PI and GI values were observed between groups and nonâsignificant trends of reduction of host response biomarkers with triclosan treatment. Triclosan significantly reduced levels of A. actinomycetemcomitans and P. gingivalis during induction of gingivitis.ConclusionsTriclosan reduced microbial levels during gingivitis development (ClinicalTrials.gov NCT01799226).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/134115/1/jcpe12519.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/134115/2/jcpe12519_am.pd
