    Study Notes

    Cysts of the Oral Cavity

    • Cysts are pathological cavities containing fluid or semi-fluid material, lined by epithelium and surrounded by connective tissue.
    • Pseudo cysts are cavities containing fluid but not lined by epithelium.
    • Odontogenic cysts originate from odontogenic epithelium remnants.
    • Non-odontogenic cysts originate from embryonic tissue remnants.

    True Cysts

    • Lined by epithelium.
    • Odontogenic cysts include gingival cysts, lateral periodontal cysts, dentigerous cysts, eruption cysts, odontogenic keratocysts, gorlin cysts (keratinizing & calcifying odontogenic cysts), inflammatory cysts (radicular and residual cysts), and lateral periodontal cysts.
    • Non-odontogenic developmental cysts include nasopalatine cysts, incisive canal cysts, palatine papilla cysts, fissural cysts (median palatal cyst, median mandibular cyst, nasolabial cyst, globulomaxillary cyst, and median alveolar cyst).
    • Pseudo cysts include traumatic bone cysts, hemorrhagic bone cysts, solitary bone cysts, aneurysmal bone cysts, and static bone cysts.
    • Soft tissue cysts include thyroglossal tract cysts, cervical lymphoepithelial cysts, dermoid and epidermoid cysts, mucous retention cysts, and mucous extravasation cysts.

    Definitions

    • Cyst: A pathological cavity containing fluid or semi-fluid material, lined by epithelium and surrounded by connective tissue.
    • Pseudo cyst: A pathological cavity containing fluid or semi-fluid material, not lined by epithelium
    • Odontogenic cyst: A pathological cyst that originates from remnants of odontogenic epithelium.
    • Non-odontogenic cyst: A pathological cyst that originates from embryonic tissue remnants

    Classification of Cysts (Origin/Histogenesis)

    • Odontogenic Cysts: Develop from remnants of the tooth-forming tissues.
    • Non-Odontogenic developmental cysts: Arise from developmental remnants of other tissues in the oral cavity.
    • Fissural cysts originate from embryonic tissue remnants.

    Classification of Cysts (Site)

    • Location in the mouth (e.g., gingival, lateral periodontal, etc.)
    • Specific locations include premaxillary, traumatic bone (solitary), and aneurismal bone cysts
    • Cysts can be located near roots of teeth, upper anterior teeth, apically of removed teeth, between roots of adjacent teeth, crown of tooth, mandible, molars, ramus, upper lateral and canine area, behind the nose, midline of palate, midline above hyoid bone, floor of mouth, below angle of mandible. Specific locations include: incisive canal, palatine papilla, median palatal, median mandibular, nasolabial, globulomaxillary, median alveolar.
    • Cysts may be associated with unerupted teeth, unerupted impacted teeth, and teeth that have been removed.

    Histological Features of Cysts

    • All true cysts have an epithelial lining.
    • All true cysts have a connective tissue wall containing collagen fibers, fibroblasts, and blood vessels.
    • All true cysts contain fluid or semi-fluid material in the cavity.
    • Some cysts may have keratin or other specific cell types within the epithelium.

    Clinical Features of Cysts

    • Pain: Many cysts are painless, but inflamed or infected cysts can cause pain.
    • Symptoms: Swelling, asymptomatic, or bleeding/infection. Symptoms can include painful or asymptomatic swelling, bleeding, craking sensation, and fluctuating swelling.
    • Radiographic Appearance: Radiolucent areas (dark areas) on x-rays, sometimes with a surrounding radiopaque margin. Appearances can vary, with some cysts appearing multilocular or unilocular.
    • Age and Sex: Some cyst types may be more common in certain age groups or genders. Females may be more commonly affected.
    • Clinical Picture/Symptoms : Detailed descriptions of symptoms (e.g., pain, swelling, bleeding), as well as potential radiographic features (e.g., rounded radiolucent area with a radiopaque margin, heart-shaped, inverted).
    • Histological Picture/Features: Detailed descriptions of epithelial and connective tissue components (e.g., keratinized/non-keratinized stratified squamous epithelium) and location.
    • Histological Picture: Detailed descriptions of epithelial and connective tissue components (e.g., keratinized/non-keratinized stratified squamous epithelium), with specific details about appearance of cells, tissues, and locations.
    • Treatment Options: Methods of treatment (e.g., extraction, surgical intervention, marsupialization).

    Other Important Information

    • Gorlin Syndrome: A genetic disorder characterized by multiple basal cell carcinomas, bifid ribs, and other symptoms.
    • Incisive Canal Cyst: Located in the incisive canal.
    • Palatine Papillary Cyst: Located at the hard palate.
    • Globular Maxillary Cyst: Located between maxillary teeth.
    • Nasolabial Cyst: Located in the nasolabial fold.
    • Median Mandibular Cysts: Located in the midline mandibular region.
    • Median Palatine Cysts: Located in the midline of the palate.
    • Dermoid and Epidermoid Cysts: Contain skin components.
    • Thyroglossal Cysts: Associated with the thyroid gland.
    • Cervical Lymphoepithelial Cysts (Branchial Cleft Cysts): Associated with the branchial arch.
    • Traumatic Bone Cysts: Related to injury, characterized by an empty cavity in the bone.
    • Aneurysmal Bone Cysts: Not true cysts; characterized by bleeding during surgery; a large cavity filled with blood.
    • Clinical Picture/Symptoms : Detailed descriptions of symptoms (e.g., pain, swelling, bleeding), as well as potential radiographic features (e.g., rounded radiolucent area with a radiopaque margin, heart-shaped, inverted).
    • Treatment: Different treatment options exist (e.g., extraction, surgical intervention, marsupialization).
    • X-ray appearance: (e.g., salt-pepper, heart-shaped, soap bubble).
    • Types: location-specific, origin-specific, etc.
    • Clinical picture : descriptions of symptoms.
    • Symptoms: Painless, asymptomatic, swelling. Additional symptoms can include: swelling, bleeding, cracking sensation, bone resorption, and fluctuating swelling.
