Acute periodontal diseases Flashcards
What are the 4 tissues that make up the periodontium?
- Gingiva
- Periodontal ligament
- Cementum
- Alveolar bone
What is an acute disorder?
Anything that is sudden and onset that forces a person to seek immediate help
What are the 4 stages of treatment?
- Emergency treatment
- Initial therapy
- Corrective therapy
- Supportive therapy
What is an abscess by definition?
An acute lesion
Name some periodontal disorders that may present in acute phase?
- Periodontal abscess
- Necrotising periodontal diseases (NPD)
- Necrotising ulcerative gingivitis / Necrotising ulcerative periodontitis
- Primary herpetic gingivostomatitis
Define what a periodontal abscess is
A localised purulent infection within the tissues adjacent to the periodontal pocket that may lead to a rapid destruction of the periodontal ligament and alveolar bone
What are the 2 broad reasons a periodontal abscess may form in a pre existing periodontal pocket ?
Due to:
- Acute exacerbation
- After treatment
How can a periodontal abscess form due to acute exacerbation?
- Due to untreated periodontitis
- Non responsive to therapy periodontitis
- Supportive periodontitis
How can a periodontal abscess form after treatment?
- Post scaling
- Post surgery
- Post medication eg some drugs or systemic antibiotics can lead to the formation of abscesses
What are some of the broad reasons a periodontal abscess may form in a non periodontal patient?
- Impaction of any foreign object
- Harmful habits like naiver biting
- Orthodontic factors and forces
- Gingival overgrowth
- Alterations of root surfaces
Name some foreign objects that can lead to the formation of abscesses in non periodontal patients/
- Dental floss
- Orthodontic elastic
- Toothpicks
- Rubber dams
- Stuck food
What can periodontal abscesses primary be classified by?
The abscesses are classified according to the source of the infection:
periapical (dento-alveolar),
periodontal
peri-coronal abscess
What can abscess in the periodontium be secondary to?
- Pulp necrosis
- Periodontal infections
- Pericoronitis
- Trauma or surgery
