18
Q

Chronic dentoalveolar (periapical) abscess drainage may occur

A

Spontaneously through fistula to surface

Drainage brings relief

19
Q

Chronic dentoalveolar (periapical) abscess fistula with parulis

A

Spontaneous o drains when pressure builds

Gum boil

Not an emergency

20
Q

Chronic dentoalveolar (periapical) abscess drainage into tissues spaces and Oreo facial involvement

A

Is serious emergency

21
Q

Cellulitis

A

Bacteria invade soft tissue

Inflammation
Edema
Erythema
Painful
Fever possible
22
Q

Edema

A

Tissues hard indurate

23
Q

Soft tissue involvement determined by

A

perforation of the cortical bone in relation to the muscle attachments

24
Q

Odontogenic facial cellulitis

A

Bacteria from tooth

A-streptococci

25
Q

No odontogenic facial cellulitis

A

Skin or mucous membrane trauma
Sinus bacteria
Hemophilia influenzae
His vaccine lowered incidence

26
Q

Other causes of acute facial swelling

A

Mumps

27
Q

Odontogenic usually located

A

More often lower face

Upper face common too

28
Q

Non odontogenic usually in

A

Usually upper face

29
Q

Cellulitis may progress

A

To new secondary abscess formation

30
Q

Secondary abscess not

A

In direct communication with primary

Most be drained for resolution

31
Q

Most frequently isolated in odontogenic facial cellulitis

A

A-hemolytic streptococci

32
Q

Antibiotics not effective against

A

Infections confined to pulp

Apical period

Abscesses

33
Q

If tooth ext or RCT does not provide a path of drainage

A

Surgical incision and drainage required for resolution

34
Q

Antibiotic selection: Penicillin/amoxicillin

A

Bactericidal
Narrow but appropriate spectrum for milder infections

Resistance possible

Amox has less frequent dosage schedule and better taste

35
Q

Penicillins w/B-lactamases inhibitor

A

Oral augmentin
IV unasyn
Resistance unlikely
Bactericidal

36
Q

Addition of metronidazole to penicillin

A

Covers anaerobes so broader spectrum

37
Q

Clindamycin

A

Oral or IV

Less resitance

Bacteriostatic

38
Q

Ludwigs Angina

A 
Drooling
Elevation of the floor of mouth
Difficulty swallowing
Breathing
Limited neck motion
Trismus
39
Q

Periorbital cellulits

A

Erythema
Induration
Tenderness of tissues
Rarely progresses to orbital cellulitis

40
Q

Orbital cellulitis

A 
More common in children
Bulging eye
Loss of vision
Pain in eye
Brain abscess
41
Q

Compensated shock

A

BP mainted by increased cardiac work

Rapid pulse

Not indefinitely sustainable

42
Q

Uncompensated shock

A

BP can no longer be maintained

Emergency

43
Q

Indications of urgency

A 
Rapid 
Fever
Pain level 
Prior treatment failure
Inability to eat
44
Q

Criteria for hospital admission

A 
Fever malaise
Rapid progression
Trismus 
Impending airway
Deep space infection
Periorbital swelling
Compromised host
Poor complicate 
Special healthcare needs
