Group 2:Historical Theories
Nonspecific plaque Hypothesis- postulated that the
accumulation of bacterial biofilms leads to periodontal. Disease
Specific Plaque hypothesis- postulated that specific
pathogenic bacteria and their products in the biofilm lead to periodontal disease... usually the red complex
(socransky’s microbial complexes)

Microbial Homeostasis- Host Response
•The way the host responds to the bacteria causes the tissue destruction
A few hours after pellicle formation, free-floating microbes attach to the outer surface of the pellicle
-
-
Contemporary Ecological Plaque
•host inflammatory response is triggered by accumulation of non-specific bacteria causing a change in the subgingival environment
•further changes in environment lead to tissue destruction & a growing of specific periodontal pathogens

Micriobial blooms, micro colonies
Layering, fluid channels, bacterial signaling

Initiated a shift from beneficial to dysbiotic in biofilm community that trigger hosts inflammatory response
