- 2-4 days
- bacterial accumulation
-
T/F migration and infiltration of WBCs into the JE and gingival sulcus result from the natural body response to infectious agents
true
-
T/F when there is an inflammatory response to dental biofilm, there is an increase of flow of gingival sulcus fluid
true
-
what is the initial lesion?
inflammatory response to dental biofilm
-
in the initial lesion there is early breakdown of ________ of the supporting gingival fiber groups
collagen
-
______ fills the spaces in the CT during the initial lesion
fluid
-
what is the clinical appearance of the initial lesion?
- no clinical evidence of change
- slight marginal redness with enlargement due to the fluid collection following as infection develops
