Acute chronic periodontitis Flashcards
What is acute periodontitis?
clinical conditions of rapid onset that involve the periodontium, or associated structures, and may be characterized by pain or discomfort, tissue destruction and infection
Examples of acute Periodontology disease?
Gingival abscesses
Periodontal abscesses
Nectrotizong periodontal diseases
Hermetic gingivostomatitis
Pericoronoitis
Endo-periodontal lesions
what is a periodntal abscess?
Is a localised accumulation of pus located within the gingival wall of the periodontal pocket/sulcus
Resulting in a significant tissue breakdown
primary signs and symptoms of a periodontal abscess?
Ovoid elevation in the gingiva
Along the lateral part of the lot
Bleeding on probing
Pain
Suppuration on probing
Deep periodontal pockets
Increased tooth mobility
is tissue break down associated with a periodontal abscess fast or slow?
Rapid
primary signs and symptoms to aid diagnosis of a periodntal abscess?
Ovoid elevation in the gingiva along the lateral part of the tooth
Bleeding on probing
Secondary signs and symptoms to aid diagnosis of a periodontal abscess?
pain
Suppuration on probing signs
Deep periodontal pockets Increased
Increased tooth mobility
are teeth with associated periodontal abscess vital?
Yes likely to be vital
tx for periodontal abscess?
Incise/drain
Debridement
Extraction
+/- antimicrobial therapy f warranted
+/- referra; t specialist of bone deformity present or deep pockets may require surgical periondianl care
why do periapical abscesses occur?
Pulp necrosis
acute vs chronic abscess?
Acute non-draining and painful
Chronic drains
2 types of people with periodntal disease?
Pre-existing periodontal pocket
Non- pre- existing periodontal pocket
what happens f you don’t clean to the ful depth of the poet?
The coronal section heals and traps in the apical area with the infection still present
Causing a periodontal abscess
if the periodontal abscess doesn’t heal, what are differential diagnosis?
Tumour lesions
Squamous cell carcinoma
Pyogenic granuloma
Osteomyelitis
Cysts
Self-inflicted gingival injuries
Sickle cell anemia
Abscesses after surgical procedures
what is acute necrotising conditions?
Are a groups of periodontal diseases witha characteristic clinical phenotype (papilla necrosis, bleeding and pain)
Periapical abscess vs periodntal abscess?
Unlike periapical lesion, teeth will likely be vital, no pain to retinal compression/percussion but may have pain on horizontal pressure
NPDs infectious or non-infectious?
Infectious
Based on host response to oral flora
risk factors for NPD?
Host response. Immune dysfunction
- pre-existing periodontal condition
- HIV/AIDs
- malnutrition
- psychological stress and sleep deprivation
- smoking and alcohol consumption
- poor OHI
- young age (15-34)
- previous NPDs
- local factors such as restorations
what are the 4 zones in NP/NG?
Superficial bacterial layer
Neutrophil rich zone - bodies response
Necrotic zone
Spirochete zone - studies have shown this to be a key marker
bacteria related to spirochete?
T. denticola
How to diagnose NP?
Clinical observation:
- necrosis/ulcer o the interdental papillae, gingival bleeding, halitosis, pain, and rapid bone loss
- secondary signs/symptoms are pseudomembrane formation, lymphadenopathy, and fever
how to diagnose NG?
Primarily include nercrosis/ulcer of the interdental papillae, gingival bleeding and pain
Secondary signs/symptoms include halitosis, pseudomembrane formation, regional lymphadenopathy, fever
necrotisin stomatitis?
Soft tissue necrosis that extends beyond the gingiva, with bone denudation that may occur through alveolar mucosa
Large areas of osteitis and formation of bone dequestrum
Soft tissue necrosis that extend beyond the gingiva
who is likely to have necrotising stomatitis?
systemically compromised patients (hiv/aids, severe malnutrition)
Must consider other systemic conditions, such as vesicular-bulbous diseases
Consider referral to OM
