Acute Periodontal Lesions Flashcards
Acute periodontal lesions include: (3)
- periodontal abscesses
- necrotizing periodontal disease
- endo perio lesions
A dental emergency makes up ____% of all emergency patients and is the ____ most common reason for ER visits
7-14%; 3rd
(periodontal abscesses)
60% of dental emergency visits are due to:
untreated periodontitis
___% of patients in active periodontal treatment result in dental emergencies
13.5%
___% of patients in periodontal maintenance results in dental emergencies (due to periodontal abscess)
37%
(these patients are doing everything right and still end up with periodontal abscesses)
Etiology of periodontal abscesses include: (6)
- pulp necrosis
- periodontal infections
- pericoronitis
- trauma
- surgery
- foreign body impaction
Localized accumulation of pus located within the gingival wall of the periodontal pocket, with an expressed periodontal breakdown occurring during a limited period of time:
Periodontal abscess
Describe the clinical symptoms of periodontal abscess:
easily detectable
What are the sequence of events leading to abscess formation: (8)
- occlusion of existing periodontal pocket
- bacterial invasion of soft tissue wall
- leukocytic infiltration (neutrophils)
- vascular thrombosis
- edema & swelling
- tissue necrosis & liquefaction
- collagenolysis & bone resorption
- production of purulent exudate
The pain from a periodontal abscess is caused by:
pressure
The most common symptoms of acute periodontal disease (in order of decreasing frequency): (4)
- pain
- swelling & edema
- lymphadenopathy
- fever
Multiple periodontal abscess formation is often a manifestation of:
- diabetes (uncontrolled or undiagnosed)
- AIDS (compromised immune system)
- Depressed immune system (steroid therapy, chemotherapy)
What is the MOST common underlying cause for multiple periodontal abscess formation?
Diabetes (uncontrolled or undiagnosed)
What type of bacteria make up 65% of microbial flora found in periodontal abscesses?
Gram-negative and anaerobes
Bacteria that produce proteinases, such as_________ and _______are important in the pathogenesis of the periodontal abscess since they increase the availability of nutrients, and thereby increase the number of bacteria within the abscess environment
P. Gingivalis & P. Intermedia
Bacteria that produce ______, such as P. Gingivalis and P. Intermedia are important in the pathogenesis of the periodontal abscess since they increase the availability of nutrients, and thereby increase the number of bacteria within the abscess environment
Proteinases
Bacteria that produce proteinases, such as P. Gingivalis and P. Intermedia are important in the pathogenesis of the periodontal abscess since they:
increase the availability of nutrients, and thereby increase the number of bacteria within the abscess environment
List some of the bacteria found in periodontal abscesses: (7)
- Treponema (spirochetes)
- Fusobacterium nucleatum
- Prevotella intermedia
- Porphyromonas gingivalis
- Peptostreptococcus micros
- Tanerella Forsythia
- Candida albicans
What type of good can trigger abscess formation?
-popcorn
-almonds with skin (& anything with skin)
-chia seeds (and any small seeds)
Histopathology of periodontal abscess includes: (5)
- acute inflammatory infiltrate
- vascular hyperemia and thrombosis
- lysis of the collagen matrix in the lamina propria and the gingival fibers
- ulceration and apical proliferation of JE
- osteoclastic mediated bone resorption
Any time you have a perio abscess you need to rule out _______
How do you do this?
Endodontic origin; sensibility test
If the abscess is draining what might you do?
Trace it on a radiograph with gutta percha points
Periodontal abscess in a periodontitis patient could represent:
disease exacerbation
Periodontal abscesses in a periodontitis patient could represent disease exacerbation. What might this be due to? (5)
- presence of a tortuous pocket
- furcation involvement
- vertical defect
- composition of microflora
- decreased host defense
When do we commonly see acute exacerbation of periodontitis leading to an abscess?
- in untreated periodontitis
- patients that are non-responsive to periodontal therapy
- patients on supportive periodontal therapy
A periodontitis patient might develop a periodontal abscess following treatment. This could occur:
- post-scaling
- post-surgery
- due to post-medications (such as antimicrobials or nifedipine)
What post-treatment medications can lead to periodontal abscesses in a patient with periodontitis?
- Antimicrobials
- Nifedipine
List some causes for periodontal abscesses in non-periodontitis patients:
- impaction of foreign bodies
- harmful habits
- orthodontic factors
- gingival enlargement
- alteration of the root surface
Non-surgical periodontal treatment is:
scaling and root planing (SRP)
Periodontal abscesses in non-periodontitis patients can be due to alteration of root surfaces such as in:
- dens invaginatus
- cemental tears or enamel pearls
- iatrogenic conditions such as perforations
- severe root damage (VRF or cracked tooth syndrome)
- External root resportion
List the clinical signs of a periodontal abscess: (10)
- pain
- localized swelling & fluctuance
- purulent exudate
- deep periodontal pocket
- tooth exhibits VITAL pulp
- fistula presentation
- tooth mobility
- sensitivity to percussion
- low grade fever
- lymphadenopathy
List differential diagnosis for periodontal abscesses: (6)
- periapical abscess
- acute pulpitis
- tooth or root fracture
- pericoronitis
- lateral periodontal cyst
- gingival cyst
