The effect of supragingival plaque control on the composition of the subgingival microbial flora in ligature-induced periodontitis in the monkey
B. Siegrist and K. S. Kornman
The influence of supragingival plaque control on the subgingival microflora
and clinical parameters of ligature-induced periodontitis in the Cynomolgus
monkey was investigated. No clinical changes were observed during the
six-week experimental period. The total cultivable flora and the
proportions of total black-pigmented Bacteroides (BPB) and asaccharolytic
black-pigmented Bacteroides decreased significantly in the cleaned test
sites as compared to those in the non-cleaned controls. The study suggests
that six wk of supragingival plaque control in the presence of periodontal
disease may alter the periodontitis-associated microflora in the monkey,
but not sufficiently to alter clinical signs of disease in this time
period.
