Study Notes
Oral Pathology 1, Lecture 12
- Pulpal & Periapical Disease II: Covers pulpitis, pulp necrosis, pulpal calcifications, periapical inflammatory disease (granuloma, cyst, abscess), cellulitis, osteomyelitis, condensing osteitis, and osteomyelitis with proliferative periostitis. Also discusses periapical inflammatory disease, including periapical granuloma, periapical cyst, periapical abscess, and acute periapical periodontitis.
- The Stages of Caries Development: Diagrams the progression of tooth decay from enamel caries through dentin caries, pulpitis to periodontal involvement.
- Periapical Granuloma (Chronic Apical Periodontitis): A lesion of chronically/subacutely inflamed granulation tissue at the apex of a nonvital tooth. Characterized by inflammation secondary to microbial infection in the root canal. Early stages (acute apical periodontitis) are dominated by neutrophils, while later stages have more chronic inflammatory cells. Radiographic findings include loss of lamina dura.
- Clinical & Radiographic Features: The initial phase of periapical inflammatory disease (acute periapical periodontitis) is characterized by constant dull, throbbing pain and negative results from vitality tests.
- Periapical Cyst (radicular cyst, apical periodontal cyst): Epithelial rests of Malassez form a cyst in the apex of a nonvital tooth. This can be asymptomatic or cause symptoms in advanced cases. Radiographs show a radiolucency, sometimes with a loss of the lamina dura.
- Residual Periapical Cyst: A periapical inflammatory lesion not treated at tooth removal, possibly leading to a cyst. Appears as a round-to-oval radiolucency.
- Lateral Radicular Cyst: A similar cyst located laterally on the root, typically arising from rests of Malassez.
- Histopathologic Features: All types of inflammatory cysts have similar features; lined by stratified squamous epithelium with scattered mucous cells. The lumen may contain fluid and debris, and the cyst wall includes fibrous connective tissue.
- Treatment & Prognosis: Treatment depends on tooth restorability (endodontics or extraction). Biopsy may be needed to rule out other pathologies. Follow-up is important.
- Acute Apical Periodontitis: Localized acute inflammation in the periodontal ligament, potentially without abscess formation.
- Periapical Abscess: Acute inflammatory cells accumulating at the apex of a nonvital tooth, often stemming from chronic lesions or a subsequent acute exacerbation. May be symptomatic or asymptomatic. Clinical presentation typically includes tenderness, severe pain, and swelling. Radiographic changes include bone loss.
