Study Notes

Periodontal Abscess

  • Odontogenic abscesses are acute infections originating from the tooth and/or periodontium.
  • Symptoms include localized purulent inflammation, pain, and swelling.
  • Abscesses are a common reason patients seek emergency dental care.
  • Classification depends on the infection's origin:
    • Periapical: in the tooth's apical third, often endodontic in origin.
    • Periodontal: related to periodontal pockets.
    • Pericoronal: related to partially erupted teeth (e.g., wisdom teeth).
  • Classification can also be acute or chronic, and single or multiple.

Types of Periodontal Abscesses

  • Periodontal Abscess: the infection originates within a periodontal pocket from a biofilm.
  • Non-Periodontal Abscess: the infection originates from a local source, like foreign body impaction.

Periodontal Abscess Etiology

  • Formation is often due to marginal closure of a deep periodontal pocket, and a lack of proper drainage.
  • Presence of deep pockets with furcation lesions is common.
  • Post-surgical abscesses may occur due to incomplete removal of subgingival calculus, foreign bodies (sutures, regenerating materials), or dental packs.
  • In advanced periodontitis patients, antibiotic treatment without subgingival debridement may lead to further infection.

Periodontal Abscess Diagnosis

  • Diagnosis is based on overall patient complaints along with clinical and radiological examinations.
  • Key sign is an ovoid gingival elevation along the tooth's lateral aspect.
  • In deep cases, abscesses may be difficult to detect due to lack of obvious swelling.
  • Abscess characteristics (e.g., pus, suppuration) may appear after pressure is applied, or may occur spontaneously
  • Other symptoms include varying levels of pain (from discomfort to severe pain), tenderness of gingival tissue, swelling, sensitivity to tooth percussion.
  • Tooth elevation and increased tooth mobility are additional signs in some cases.

Periodontal Abscess Treatment

  • Treatment typically involves two phases:

    • Management of the acute infection.
    • Management of the original infection after the acute phase has concluded.

  • Treatment options for the acute phase include:

    • Incision and drainage
    • Scaling and root planing
    • Periodontal surgery
    • Systemic antibiotics
    • Tooth extraction (when necessary).

  • Mechanical treatment alone might damage healthy surrounding tissue -- therefore antibiotic therapy is sometimes chosen as a first approach for initial treatment.

  • Mechanical debridement (including root planing) follows the acute phase when appropriate.

Periodontal Abscess Complications

  • Tooth loss: periodontal abscesses are a primary cause of tooth extraction in supportive periodontal therapy.
  • Dissemination of infection: systemic infections from the abscess can affect various parts of the body.
  • Risk of infection spreading via the bloodstream (bacteremia).

Differential Diagnosis Considerations

  • Periodontal abscesses can present similarly to other types of oral abscesses. The lack of vital pulp in the tooth; the presence of deep caries lesions; and radiological findings can be used to differentiate different types of oral abscesses.

Histopathological Considerations

  • Histopathologic examination might be needed to rule out possible squamous cell carcinoma.
