    Study Notes

    Pulpitis

    • Pulpitis is inflammation of tooth pulp due to bacterial invasion, leading to swelling and pain.
    • Causes include dental caries, traumatic pulp exposure, crown or cusp fractures, cracked teeth, and thermal or chemical irritation.
    • Acute pulpitis presents with sharp sensitivity to temperature changes, evolving into persistent pain.
    • Chronic pulpitis may occur with or without episodes of acute conditions; pain can be dull, and pulp necrosis may happen without significant symptoms.

    Types of Pulpitis

    • Acute Pulpitis: Initial hypersensitivity to hot/cold; pain worsens with inflammation and can become spontaneous.
    • Chronic Pulpitis: Characterized by prolonged remissions and possible pulp death, leading to periapical periodontitis.

    Pathology of Pulpitis

    • Caused by caries, infiltration of acidic bacterial products, and the progression of inflammation.
    • Histological features include hyperemia, inflammatory cell infiltration, and potential abscess formation.

    Symptoms of Pulpitis

    • Severe tooth pain and increased sensitivity; tooth may be painful under pressure and tapping.
    • Presence of an abscess can lead to extreme sensitivity.

    Management of Pulpitis

    • Stabilization of fractures, removal of caries, pulp capping, pulpotomy (in children's teeth), endodontic treatment, or extraction.
    • Analgesics generally provide little relief.

    Apical Periodontitis

    • Local inflammation of periapical tissues due to pulp disease, resulting from dental caries or trauma.
    • Symptoms include pain, tenderness, and possible tooth discolored from pulp necrosis.
    • Diagnosis includes clinical examination, radiographic assessment, and pulp vitality testing.

    Treatment Options for Apical Periodontitis

    • Non-surgical root canal therapy, apicoectomy, periapical curettage, and appropriate antibiotics if necessary.

    Dentoalveolar Abscess

    • An acute lesion characterized by pus localization at the apex of a non-vital tooth.
    • Common causes include acute apical periodontitis, deep caries, trauma, or failed dental procedures.

    Clinical and Radiographic Features of Dentoalveolar Abscess

    • Symptoms range from tenderness to pressure sensitivity, intense pain, swelling, and malaise.
    • Radiographically, may show thickening of the apical periodontal ligament and ill-defined radiolucency.

    Management of Dentoalveolar Abscess

    • Incision and drainage of the abscess, root canal treatment, extraction if necessary, and antibiotics for infection control.

    Apical Granuloma

    • A localized mass of chronic granulation tissue at the root apex of a non-vital tooth, often due to chronic periapical periodontitis.
    • Forms following pulp necrosis and persistent inflammation due to bacteria and necrotic tissue.

    Diagnosis and Treatment of Apical Granuloma

    • Typically asymptomatic, may flare up with acute exacerbations, diagnosed via radiology showing radiolucent areas around the root.
    • Treatment options include root canal therapy, antibiotics, apicoectomy, or extraction.

    Apical Cysts (Radicular Cysts)

    • Epithelial-lined cysts originating from a non-vital tooth, often resulting from dental granulomas or untreated infections.
    • Divided into apical, lateral, and residual cysts based on their anatomical location relative to the tooth root.

    Types of Apical Cysts

    • Apical Cyst: Most common type associated with non-vital teeth.
    • Lateral Cyst: Radiolucencies found along the lateral aspect of the root.
    • Residual Cyst: A cyst left after the extraction of the original tooth, appearing as a rounded radiolucency.
