-
what prevents food impaction?
interdental papilla
-
it is between the teeth and also known as interdental papilla.
interdental gingiva
-
where is the col located?
apical to the contact area
-
a concavity in the interdental papilla that forms between the lingual and facial gingival surfaces
col
-
what three things describe attached gingiva?
-
a thick layer of parakeratinized epithelium which blocks the vascular supply in the lamina propria
pink attached gingiva
-
tall narrow papilla in the lamina propria that pull on the epithelium and cause dimples
stippled
-
when there is swelling in the gingiva, what goes away?
stippling
-
attached gingiva is ________ and firmly attached to the ______ beneath it
-
why are gums red when someone has perio?
there is more blood supply which makes it more visible
-
what two things are present when there is inflammation?
-
pain, heat, erythema, edema, loss of function are examples of:
inflammation
-
the tissue is red because of increased blood flow is called:
erythema
-
edema is when the _________ papilla is ________ as it is filled with ______ fluid. this edema may cause the tissue to loose its ________.
- interdental
- enlarged
- tissue
- stippling
-
when gums "pull down" they expose the root surface. this is called:
gingival recession
-
in gingival recession, the ______ gingival margin starts to move ______. usually exposing _______ which can cause _________.

- apically
- cementum
- sensitivity
-
what five things can cause gingival recession?
- perio disease
- tooth position
- incorrect toothbrushing
- occlusal stress
- strong frenal attachments
-
what is measured from the CEJ to the free gingival margin?
gingival recession
-
overgrowth of the interdental papilla
gingival hyperplasia
-
gingival hyperplasia is usually caused by poor ______ ________ and certain ________
-
what are the three meds that can lead to gingival hyperplasia?
