The effect of supragingival biofilm re-development on the subgingival microbiota in chronic periodontitis

In this study, we hypothesized that in the absence of oral hygiene, re-growth of the climax microbial communities of supra and subgingival biofilm happens in a faster and more intense fashion in individuals with chronic periodontitis (CP) compared to periodontally healthy controls (PH). Thirty patients (PH = 15 and CP = 15) received professional supragingival prophylaxis, and were asked to refrain from oral hygiene for 7 days. Supra and...
