44
Q

ludwigs angina location and origin

A

cellulitis of submandibular region
70% from lower molar teeth infx
also tonsillar/pharyngeal abscess, oral laceration, frx of md or dub-md sialadenitis

more in AIDS, tranplsant, aplastic anemia, diabetes pts
airway obstruction major concern

45
Q

tongue in ludwig

A

woodt

elevated, enlarged, protruded when Ludwig in subligual space

46
Q

neck in ludwig

A

bull

enlarged and tender (subMD space spread)

47
Q

cavernous sinus thrombosis location and origin

A

cavernous sinus in dura; mx infections

48
Q

cavernous sinus thrombosis clinical look

A

periorbital enlargement involving eyelid and conjunctiva

proptosis, chemosis (conjunctival edema), ptosis in 90% of cases

49
Q

osteomyelitis locations

A

most in MD of males

mx cases when assoc w NUG or noma

50
Q

three categoreis of diffuse sclerosing osteomyelitis

A

diffuse sclerosing osteomyelitis – infx present
primary chronic osteomylitis – similar to classic chronic but no bacteria, suppuration, or sequestra
chronic tendoperiostitis

51
Q

chronic tendoperiostitis

A

primary chronic osteomylitis 2/2 overuse of masseter (MD angle/body) or digastric (anterior MD/PM region)

can see parafunctional habits (bruxism, clenching, nail biting)

52
Q

SAPHO molecular basis

A

autoimmune to derm bacteria, cross react with bone

poss HLA-B27?

53
Q

CRMO and skin

A

chronci recurrent multifocal osteomyliis

no skin lesions but can appear up to 20 years later – palmoplants pustulosis, psoriasis, acne, hidradenitis suppurativa

54
Q

condensing osteitis aka, who, where

A

focal sclerosing osteomyelitis
localized areas of bone sclerosis assoc w apices of teeth w pulpitis or necrosis
children and young adults
ddx: FCOD (has RL border) and idiopathic osteosclerosis (separated ffrom apex)

55
Q

bone scar

A

residual area of condensing osteitis after imflammation resolves

56
Q

residual area of condensing osteitis after imflammation resolves

57
Q

garre osteomyelitis better term:

most – osteomylitis and neoplasms (Ewing sarcoma, LCH, osteosarc, hemangioma)

also: trauma, cysts, infantile, cortical hyperostosis, fluororis,s avitaminosis C, hypertrophic osteoarthropathy, and congenital syphilis)

60
Q

histo periosteal rxn to inflammation

A

parallel rows of vital bone

61
Q

locations for periosteal rxn to inflammation

A

most are unifocal in molar and PM 2/2 caries

also perio infx, frx, buccal bifurcation cysts, and non-odontogenic infx

62
Q

dry socket what happened

A

clot is lost –> bare bony socket

63
Q

why can clot get lost

A

trauma, estrogen, bacteria can stimulate fibrinolysins
increased freq in impacted 3 molars, poor oral hygiene, inexperienced surgeon, traumatic exo, oral contraceptive use, and presurgical infx (pericoronitis)

also inadeq irrigation, smoking, heavy spitting/sucking

64
Q

dry socket tx:

A

xray to rule out tip or foreign body

irrigation, analgesics, maybe topical abx

65
Q

normal pulp:

cold, heat, electric, percussion, pain

A 
cold - 1-2 sec
heat - no 
EPT - normal 
percussion - no 
pain - severe
66
Q

reversible pulpitis:

cold, heat, electric, percussion, pain

A 
cold - acute pain, sweets also
heat - sometimes
EPT - lower
percussion - no 
pain - acute
67
Q

irreversible pulpitis:

cold, heat, electric, percussion, pain

A 
cold - early: uncomfy; lateL cold relieves pain
heat - severe/sharp
EPT - early: low; late: high
percussion - no 
pain - throbbing lingering
68
Q

periapical infection clinical

A

acute: dull throbbing pain, negative or delayed vitality, pain on percussion
chronic: no pain

69
Q

reactionary vs reparative dentin

A

 Reactionary: mild stimuli

 Reparative: Severe stimuli; first – interface dentin = atubular + acellular = fibrodentin

70
Q

detectable pulpal calcs

A

> 200 μm to be detected by radiograph

71
Q

ludwig and teeth:

A

70% related to molars
submand/subling/submental spaces
submand –> pharyng –> retropharyng

72
Q

cavernous sinus thrombosis and teeth

A

10% related to teeth
anterior pathway: canine tooth –> canine space –> valveless facial veins –> angular vain –> inf ophth vein –> sinus

psoterior pathway: mx PM/M –> buccal/infratemporal space –> emissary vein –> inferior petrosal sinus –> cavernous sinus

73
Q

SAPHO what is, cause, location, components

A 
cause unknown, individuals with Autoimmune are predisposed
 Axial skeleton (anterior chest)
 Concurrent neutrophilic skin
 Adults
 -ve for bacteria
Synovitis
Acne
Pustulosis
Hyperostosis
Osteitis that mirrors primary chronic osteomyelitis
74
Q

A 
Believed to be a pediatric variant of SAPHO or wide spread variant of primary chronic
osteomyelitis.
Chronic
Recurrent
Multifocal
Osteomyelitis
