-
which lesion is the inflammatory response to biofilm?
initial lesion
-
which lesion is the increased inflammatory response?
early lesion
-
which lesion is the progression from the early lesion?
established lesion
-
which lesion is the extension of inflammation?
advanced lesion
-
which inflammation occurs within 2-4 days from irritation of bacterial accumulation?
initial lesion
-
which lesion does dental biofilm become older and thicker in 7-14 days?
early lesion
-
which lesion is this?
infiltration of wbc's increase flow of gingival sulcus fluid, breakdown of collagen, and fluid filled space in connective tissue
no clinical evidence of change
slight marginal redness with enlargement from fluid collection as infection develops?
initial lesion
-
which lesion is this?
infiltration of fluid, lymphocytes, neutrophils
epithelium proliferates
epithelial extension and rete ridges form
early gingivitis; reversible when biofilm is controlled
JE migrates
early lesion
-
which lesion is this?
fluid and leukocyte migration increases
formation of pocket epithelium
proliferation of JE and SE wall out inflammation?
established lesion
-
which lesion is this?
pocket epithelium is more permeable
early pocket formation
collagen destruction continues
some lesions may remain stable for a long time
marginal redness, BOP, spongy marginal gingiva
established lesion
-
which lesion is 5mm or more?
advanced lesion
-
which lesion is this?
supragingival biofilm is the source for subgingival biofilm
biofilm microorganisms provide irritants
alveolar bone destruction
inflammation enters bone through small vessel channels in alveolar crest
inflammation spreads through bone marrow and out PDL
advanced lesion
-
when epithelium migrates along root surface
coronal JE becomes detached
exposed cementum where sharpeys fibers were attached
diseased cementum contains a thin layer of endotoxins from bacterial breakdown
what is this?
progression of destruction of connective tissue (in the advanced lesion)
-
what are characteristics of the advanced lesion? 8
- pocket formation
- mobility
- bone loss
- furcation
- plasma cells predominate
- je continues to migrate
- lesion extends through CT
- activity and inactivity periods
-
what is case type I?
gingival disease
-
what is case type II?
early periodontitis
-
what is case type III?
moderate periodontitis
-
what is case type IV?
advanced periodontitis
-
which case type is:
the inflammation of the gingiva
changes in color
gingival form, position, surface appearane
presence of bleeding and or exudate?
case type I gingival disease
-
which case type is 1-3mm?
gingival disease type I
-
which case type has progression of the gingival inflammation into the deeper perio structures and alveolar bone crest with slight bone loss?
case type II early perio
-
which case type is there usually a slight loss of CT attachment and alveolar bone?
case type II early perio
-
which case type has a lot or no calc, 1-5mm?
case type II early perio
-
which case type has increased destruction of the perio structures and noticeable loss of bone support, esp on radiographs?
case type III moderate perio
-
which case type has increase in tooth mobility, may or may not have furcation involvement with multi-rooted teeth?
case type III moderate perio
-
which case type is 4-6mm?
case type III mod perio
-
which case type has further progression of perio with major loss of alveolar bone support?
case type IV advanced perio
-
which case type is usually accompanied by increased mobility, and furcation involvement?
case type IV advanced perio
-
which case type is >7mm?
case type IV advanced perio
