Study Notes
Cysts in and around the Jaws
- Cysts are pathological fluid-filled cavities lined by epithelium.
- They are a common cause of chronic swellings in the jaws.
- Cysts have a wall of fibrous tissue surrounding a central lumen lined by epithelium.
- Cysts are categorized as odontogenic or non-odontogenic.
Cyst Classification
-
Odontogenic Cysts (90%): Originate from dental structures.
- Periapical (Radicular) Cysts (70%): Most common odontogenic cyst. Located at the apex of a non-vital tooth.
- Dentigerous Cysts (15%): Surround the crown of an unerupted tooth.
- Keratocysts (5%): Tendency to recur, characterized by parakeratinized lining epithelium.
- Lateral Periodontal Cysts (3%): Located between roots, often associated with vital teeth.
- Glandular Odontogenic Cysts: Rare, with a lining resembling ameloblastoma epithelium.
- Calcifying Odontogenic Cysts: Produce radiopaque flecks in the cyst.
- Orthokeratinized Odontogenic Cysts
-
Non-Odontogenic Cysts (10%): Originate from non-dental structures.
- Nasopalatine Canal Cysts: Most common non-odontogenic cyst.
- Nasolabial Cysts: Rare, form outside the bone.
- Sublingual Dermoid Cysts: Located beneath the tongue.
- Thyroglossal Duct Cysts: Embryological remnants, common in neck.
- Branchial Cysts: Embryological remnants located in the neck region
-
Pseudocysts: Lack epithelial lining, include simple bone cysts or aneurysmal bone cysts.
Cyst Features
- Growth: Slowly enlarge, either via hydrostatic pressure, wall growth, or resorption of medullary bone.
- Fluid Content: Typically watery, opalescent, thick and white (keratocyst), viscous, yellowish, or with pus (infected).
- Radiographic Appearance: Often radiolucent with a rounded shape and sharp outline; may be unilocular (single cavity) or multilocular (multiple cavities).
- Location: May affect various jaw areas, influencing the expansion direction of the cyst (buccal, lingual).
General Cyst Characteristics
- Asymptomatic: Initially asymptomatic, symptoms develop if infected or growth is significant.
- Tooth Vitality: Usually does not affect tooth vitality unless infected.
- Clinical Presentation: Often a slow, painless swelling, sometimes bluish appearance if expanded beyond the cortex.
- Diagnosis: Radiographic examination coupled with biopsy. Combination of radiographic appearance, non-vital tooth, and histological examination aid in diagnosis.
Treatment
- Treatments vary depending on the cyst type and the severity.
- Common treatments include enucleation, curettage (removal of lining and scrap the cavity) or marsupialization (a surgical procedure to create an opening).
- Treatment should be supplemented with antibiotics and drainage for infected cysts.
