what are the four stages of development of gingivitis and peirodontitis?
an inflammatory response to dental biofilm occurs within ___-___ days of irritation from _________ __________
T/F migration and infiltration of WBCs into the JE and gingival sulcus result from the natural body response to infectious agents
T/F when there is an inflammatory response to dental biofilm, there is an increase of flow of gingival sulcus fluid
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
______ fills the spaces in the CT during the initial lesion
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
which lesion is the increased inflammatory response?
the early lesion
the dental biofilm becomes _____ and _____ in the early lesion in _____-_____ days (different for individuals)
older and thicker
in the _______ lesion, epithelium ________: epithelial extensions and _____ ridges are formed (JE migrates)
infiltration of fluid, lymphocytes, and neutrophils with few plasma cells into the CT is what lesion?
(too) early (in the morning) lesion
clinical signs of the early lesion (3)
lesion is established
fluid and LEUKOCYTE migration into tissues and sulcus increase is _________ lesion
the formation of the pocket epithelium in the established lesion is what three things?
-proliferation of the junctional and sulcular epithelium
-pocket epithelium- more permeable, ulceration of lining epithelium
-early pocket formation
collagen destruction continues, CT fiber support lost. Progression to early periodontal lesion possible. which lesion is this?
describe the clinical appearance of established lesion
spongy marginal gingiva
