Q

is periapical abscess symptomatic or asymptomatic

A

generally symptomatic, but may be asym. if there is a lack of accumulation of purulent material due to chronic path of drainage

Q

how can you tell the difference between cyst, abscess, and granuloma since all deal with non-vital tooth?

Q

is parulis acute periapical inflammation or chronic periapical inflammation

A

acute

20
Q

localized collection of pus that has accumulated (consolidated) in a tissue cavity, producing fluctuance

A

abscess

21
Q

dental abscess that drains extraorally, through the overlying skin

A

cutaneous sinus tract

22
Q

opening into sinus

A

oroantral fistula

23
Q

sinus tract vs. fistulous tract
what is this^

-from within to the exterior
-parulis is the end

A

sinus tract

24
Q

sinus tract vs. fistulous tract
what is this^

-connects two anatomic cavities
-oroantral, oronasal
-tracheo-esophageal

A

fistula

25
Q

diffuse spread of an acute inflammatory process through the fascial planes of soft tissue producing erythema, edema, warmth, and pain

A

cellulitis

26
Q

when abscess is unable to establish frainage into the oral cavity or onto the surface of skin (sinus tract)

A

cellulitis

27
Q

aggressive, rapidly spreading cellulitis involving multiple anatomic spaces such as:

A

Ludwig’s Angina

spaces:
submental, sublingual, submandibular

28
Q

produces massive swelling of neck that may extend close to clavicles and cause airway obstruction

A

ludwig’s angina
[medical emergency!]

29
Q

valveless venous system may allow retrograde spread of infection from middle third of the face (can lead up to brain)

A

cavernous sinus thrombosis

30
Q

formation of a blood clot within the cavernous sinus, a major dural venous sinus, life-threatening infection
-may be associated with spread of infection from maxillary teeth

A

cavernous sinus thrombosis

31
Q

bacterial infection of bone

-NUG, NOMA (developing countries)

A

osteomyelitis

32
Q

what are predispositions that can cause osteomylitis

A

-chronic systemic diseases
-immunodeficiency
-decreased vascularity of bone

33
Q

acute vs chronic osteomylitis

A

acute
-spread through medullary spaces
-minimal tissue reaction
-more painful

chronic
-prominent tissue reaction: granulation tissue and fibrosis
-less painful

34

fragment of necrotic bone separated from adjacent vital bone that usually undergoes spontaneous exfoliation

A

sequestrum

35
Q

non-vital bone, encased by vital bone

A

proliferative periostitis

37
Q

osteomyelitis with proliferative periostitis =

A

garre osteomyelitis

38
Q

what is seen most frequently in children and young adults in the mandibular molar and premolar area involving the lower border or buccal cortex

A

proliferative periostitis (when you see onion on scan)

39
Q

what occurs with proliferative periostitis

A

periosteal reaction in which layers of reactive vital bone are formed, producing cortical expansion

40
Q

localized area of bone sclerosis associated with apices of teeth with pulpal disease

-seen mostly in children and young adults involving the mandibular molars and premolars

A

condensing osteitis
(focal chronic sclerosing osteomyelitis)
