Study Notes
Odontogenic Cysts
- Definition: Odontogenic cysts are cysts that originate from odontogenic tissues, including enamel, dentin, and pulp.
- Characteristic feature: Epithelial-lined cavities that can arise from various parts of the tooth-forming apparatus.
Types of Cysts
- Odontogenic keratocyst: Characterized by epithelial proliferation resulting in necrosis of central cells.
- Non-odontogenic cyst: Characterized by the absence of odontogenic epithelium.
- Fissural cyst: A type of non-odontogenic cyst that may prevent the eruption of teeth.
Apical Cyst
- Definition: A type of odontogenic cyst that arises from the apical region of a tooth.
- Histogenesis: Derived from the epithelial rests of Malassez.
- Clinical feature: Often asymptomatic, but can cause pain and swelling.
- Radiographic appearance: Radiolucent lesion at the apex of a tooth.
- Connective tissue wall: May contain inflammatory cells and blood vessels.
- Epithelial lining: Typically simple cuboidal or flat.
- Cystic cavity fluid: Straw-colored fluid with protein and inflammatory cells.
- Clinical manifestation: Compression of the inferior alveolar nerve can cause numbness or paresthesia of the lip and chin.
- Aspiration biopsy: Reveals the nature of the lesion, helping to differentiate between cysts and tumors.
Infected Apical Cyst
- Behavior: May behave like an abscess, with pain, swelling, and pus.
Miscellaneous
- Aneurysmal Bone Cyst is an example of a non-odontogenic cyst.
- Odontogenic cysts can have a significant impact on dental health and may require surgical intervention.
- Cyst-like lesions often have a characteristic fluid-filled cavity.
