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.
