Dental Abcess Flashcards
Which bacteria found in dental ABCESS ?
Facultative anaerobic
Anaerobic
How to diagnose ?
Areas of tenderness
Fluctuance
X ray , CT scan
Why does the best treatment for ABCESS in incision and drainage ?
Cause no blood stream in the ABCESS , so AB diffuse so far from the ABCESS it may reach peripheral bacteria not the middle .
What do we do after incision and drainage ?
Water salt rinse
Pain medications
Regular checkup
How can we get dental ABCESS ?
Pathogenic microorganisms mainly anaerobic from
Necrotic pulp TO periapical
Gingival crevice TO , PDL
The fate of ABCESS depend on ?
Number and virulence of invading microorganisms
Resistant of patient ( immunity and systemic status )
Which factors governed infection spread ?
Tooth position in the arch and the proximity to cortical plates
Tooth apices relation to muscle attachment
Thickness of bone adjacent to affected tooth
Root anatomy and position espicially wisdom teeth
What’s happen once the ABCESS get broken through alveolar bone surface ?
It’s happen usually Buccally , and may spread into deeper tissue of head and neck
What’s the main symptoms of ABCESS ?
Local pain and swelling
Generalized fever and malaise
Affected tooth loosen
Fistula drain into much and checks
Can erode into : nasal sinus = sinusitis
Floor of mouth , neck
Why if the ABCESS still acute we discover fistula ?
Cause ABCESS coming after the periodontitis , usually the chronic forms and in the chronic form in most of cases fistula develop
Espicially the granulating periodontitis
What’s is ABCESS and phlegmon ?
Abcess = Periostitis
Cellulitis = phlegmon
What’s happen if acute ABCESS didn’t healed , by extraction , RCT , antibiotics , of self healing ?
Progress into chronic alveolar abcess
Does the chronic alveolar ABCESS heal by itself as in acute form ?
No never , but it persist as a lesion ( assymptomatic ) of low grade virulence
characterized of a typical granuloma
What’s happen or how does chronic ABCESS and periapical granuloma progress ?
Are generally assymptomatic or until reignited in an acute phase
Only the development of acute exacerbation would lead to cardiac signs of inflammation
Fistula = inta and extra oral
Epithelial cells stimulation to produce dental cyst
What’s X ray changes of both phases ?
Acute = thinking of periodontal space THEN apical Lamina dura loss
Radiolucency with ill defined margins
Chronic = apical cyst or granuloma
Well circumscribed radiolucency
