plaque

A

hard biofilm

-in 48 hours

21
Q

saliva

A

can buffer acid formed by these bacteria in plaque

22
Q

strep mutans

A

gram +
facultative aerobe
favors anaerobic

metabolize sucrose to glucose and fructose

lactic acid production

23

gingivitis

A

inflammation of mucosa surrounding tooth

deposit of plaque below gumline

24
Q

peridontitis

A

inflammation of peridontal ligament, alveolar bone and cementum

can be component of systemic disease - AIDS, leukemia, crohns, DM, down syndrome, etc.

25
Q

bacteria of peridontitis

A

aggregatibacter actinomycetemcomitans

porphyromonas gingivalis

prevotella intermedia

26
Q

radicular cyst

A

pulpal necrosis seconary to cavity

infection can cause pain

radiograph dark area around apex of tooth root

aka periapical

can lead to abscess or fistula

lined with squamous epithelium

27
Q

swelling of jaw

A

possible radicular cyst

28
Q

cavernous sinus thrombosis

A

infection from mouth or face drained to cavernous sinus by venous plexus

thrombosis of internal carotic - brain ischemia

or CN IV - abducens nerve to lateral rectus of eye - horizontal diplopia

29
Q

horizontal diplopia, swollen eye, headache

A

cavernous sinus thrombosis

30
Q

ludwigs angina

A

inflammation mouth - compression of airway

stridor and difficulty breathing

31
Q

risk fx for peridontitis

A

genetics, poor oral hygiene, diabetes, ehler danlos syndrome

32

loose teeth, infection, bad breath, tooth loss

A

peridontitis

35

graded based on distance of attachment loss

36
Q

LL-37

A

low in individuals with peridontal disease

37
Q

kostmanns disease**

A

severe congenital neutropenia
-with secondary AML

low LL-37 - associated peridontal disease

G-CSF - cures neutrpenia - but not peridontitis

need BM transplant to increase the LL-37

aphthous ulcer

never blisters**

hurt, go away quickly
