Dental Abscess & Salivary Gland Infections Flashcards
what are some interchange and imprecise dental abscesses
dentoalveolar periapical apical chronic periapicaldental infection dental pyogenic infection periapical periodontitis
what are the features of a dentoalavelar abscess
carious lesion
bac to pulp via tubules
acute inflam or chronic localisation
what sit he acute inflammation caused by dentoalveolar access
pulpitis
necrosis of pulp
what is the chronic localisation of dentoalveolar abscess
abscess
pulp remains viable
what can cause a dentoalvolar abscess
trauma - fracture
anarchoresis - rare, seeding via pulpal blood supply
how is the spread of dentoalveolar abscesses spread
access soft tissue
direct spread - localised
indirect spread - moved to new sites
what are the symptoms assc with abscesses
pain
swelling
erythema
suppuration
what are the key factors asscw with abscesses
num of virulent bac
locala nd systemic immunity
anatomical damage
what are some facultative anaerobes ascs withabsecsses
s anginosus (beta haem)
s oralis
enterococcus faecalis
actinomyces
what are some strict anaerobes assc with abscesses
peptostreptococcus porphyromonas gingivalis prevotella fusobacterium nucelatum tannerella forsythia
what is the usual treat for absesse
specimen collection - needle aspiration
drain pus
amoxicillin
metronidazole
what is a periodontal abscess
infection of periodntium acute or chronic
what is the cause of perio abscess
occlusion of openign prevents drainage
impaction of foreign objects
what are the symptoms of perio disease
sudden onset
swelling
redness
may spread destroy bone
what are the micro organisms assc with a perio abscess
GNAB - porphyromonas and preveotella
S Cocci
treponema actinomyces
F. nucelatum
propionobac
what is prescribed for perio abscess
penicillin, erythromycin or metronidazole
hat are some gm -ve bac assc with infection after root canal
F nucelatum
prevotella
campylobacter rectus
what are some gm +ve bac assc with infection after root canal
s oralis/mitis, anginosus, gordonii
enterococcus faecalis
candida albicans
lactobacilli
what is enterococcus faecalis
facultative anaerobe in intetsine adhere to colagen biofilm form resist CaOH/NaOH
what is a dry socket
localised osteomyelitis
follow extraction socket not heal
anaerobic infection
what si done if a dry socket is present
prophylaxis
- chlorhexidine irrigation prior to and post extraction
treat
antiseptic dress and metronidazole
what is the cause of a abscess in edentulous treat of dental implants
trauma - overheat bone
persistence of root particle
infection of implant site
implant to infected site
what si the assc bac of abscess in implant site
s areus
mostly s epidermis
- fusobac
- anaerobic s cocci
what is ludwig angina an example
anaerobic infection
when does ludwig appear and why are the symptoms
- post extraction bilateral infection (sibling/mand)
- base mouth and tongue swell
- brawny oedema
- airway obstruction by tongue
what are some oral commensals of ludwig angina
porphyromonas prevotella fusobac anaerobic strepcocci staph
what are ways of ensuring airway remains open in ludwig angina
surgical intervention
drainage
parenteral hydration
what is the Ab for ludwig angina
intravenous penicillin
ceftriaxone and metornidazoel
what is oseteomyleitits of jaw
inflame of medullary cavity of mandible or maxilla
what are the acute and chronic ways of osteomyletis of the jaw
acute - pain, mild fever
loosening of teeth
xuate pus
chronic - tender
indurated skin
few symptoms
wha are the assc endogenous oral flora in oseomyleits of jaw
tannerella prevotella porphyromonas M. TB T apllidum
what is post radiation therapy
necrosis of blood supply - reduced salivary flow
- exogenous bac ( e coli )
what are some bac infection of salivary glands
acute/chronic bac parotitis
recurrent parotitis
submand sialadentitis
what are some predisposing factors of acute bac parotitis
drugs
abnormalities
derealised sialectasis
wat si the presentaron of acute bac paotitis
swell parotid gland
pain
purulent sec
rarely fever and chills
what s assc microbe of acute parotitis
s aureus
oral streps
haemophilia
anaerobes
what is the treat of acute parotitis
co- amoxiclav
flucloxacillin
salvation - increased fluid intake pushing
what is chronic parotitis
recurrent infection
sjorgens syndorme
fibrosis
destruction of gland
what are causes of parotitis of children
duct abnormalities
preceding mumps
foreign body
trauma
what is submandibular sialadenitis
rare
similar to acute parotitis
calculi or strictures
treat like acute
