- gingival fluid
- .5-3 mm
-
what is the epithelium on the inside of the sulcus?
sulcular epithelium
-
what is the deeper extension of the sulcular epithelium and lines the floor of the gingival sulcus and is attached to tooth surface?
junctional epithelium
-
what is the definite location of attachement between epithelium and enamel, cementum or dentin
epithelial attachement
-
while probing, the ______ ______ stops your probe at the bottom of the sulcus.
epithelial attachement
-
what are the five types of dentogingival junctional tissues?
- dentogingival junction
- gingival sulcus
- sulcular epithelium
- junctional epithelium
- epithelial attachment
-
what are the six types of gingival tissues?
- attached gingiva
- marginal gingiva
- free gingival crest
- free gingival groove
- interdental gingiva
- col
-
____ ____ has a tightly paced epithelium with many desmosomes
sulcular epithelium
-
_____ _____ has a smooth junction between the epithelium and lamina propria, no papilla
sulcular epithelium
-
how is sulcular epithelium classified?
nonkeratinized stratified squamous epithelium
-
how is junctional epithelium classified?
nonkeratinized stratified squamous epithelium
-
_____ ______ has loosely packed epithelium with fewer desmosomes
jnctional epithelium
-
what is more permeable so white blood cells can come from the blood vessels into the lamina propria and migrate into the epithelium?
junctional epithelium
-
in junctional epithelium what do the white blood cells do?
keep the tissue healthy by protecting it from bacterial plaque
-
which epithelium is thin?
junctional epithelium
-
_____ ______ is thin epithelium only _____ cells thick
-
the basal layer in junctional epithelium reproduces cells by ______
mitosis
-
in junctional epithelium cells don't fill with ______ or _____ like normal layers of epithelium
-
what are the two types of attachment for sulcular epithelium and junctional epithelium?
- external basal lamina
- internal basal lamina
-
_____ ____ _____ is just the basement membrane, it is the velcro between the epithelium and the lamina propria
external basal lamina
-
_____ _____ ____ is a new basement membrane, the velcro between the epithelium and the tooth
internal basal lamina
-
what kind of basement membrane is on the inside of the suclus?
internal basal lamina
-
which kind of basement membrane is both the lamina lucida and the lamina densa layers?
internal basal lamina
-
_____ basal lamina is continuous with the _____ basal lamina
-
what is the development of dentogingival junctional tissues?
- ameloblasts secrete the initial basal lamina and develop hemidesmosomes
- during active eruption, the tissue peels awa, but remains attached at the cementoenamel junction. This forms the initial junctional epithelium
- the definitive junctional epithelium is formed by differnetiation of the cells from the reduced enamel epithelium
-
the whole process of development of dentogingival jucntional tissue takes how long?
3 to 4 years
-
what is the turnover time of junctional epithelium?
4-6 days
-
junctional epithelium has an increased ______ allowing ______ out but allowing _____ in
-
______ is described as acute inflammation and is reversible.
gingivitis
-
_____ is ulceration of the epithelium exposes ______ ______ of the lamina propria, because of this what could happen with probing?
- gingivitis
- blood vessels
- can injure these vessels and you will get bleeding on probing
