Study Notes
Odontogenic Pathology
- Odontogenic pathology encompasses a range of cysts and tumors.
-
Cysts are classified as either developmental, inflammatory, or odontogenic, and non-odontogenic.
- Inflammatory cysts include radicular cysts, inflammatory collateral cysts, and buccal bifurcation cysts.
- Developmental cysts include dentigerous cysts, odontogenic keratocysts, lateral periodontal cysts, gingival cysts (both newborn and adult), glandular odontogenic cysts, calcifying odontogenic cysts, and orthokeratinized odontogenic cysts.
- Non-odontogenic cysts include nasopalatine duct cysts.
-
Benign tumors can be epithelial, mixed (epithelial + mesenchymal), or mesenchymal.
- Epithelial tumors include adenomatoid odontogenic tumors, squamous odontogenic tumors, calcifying epithelial odontogenic tumors, ameloblastomas (unicystic and extraosseous), metastasizing ameloblastoma, and adenoid ameloblastoma.
- Mixed tumors include odontoma, primordial odontogenic tumors, and ameloblastic fibromas.
- Mesenchymal tumors include odontogenic fibromas, cementoblastomas, cemento-ossifying fibromas, and odontogenic myxomas/myxofibromas.
-
Malignant tumors include sclerosing odontogenic carcinoma, ameloblastic carcinoma, clear cell odontogenic carcinoma, ghost cell odontogenic carcinoma, primary intraosseous carcinoma (NOS), odontogenic carcinosarcoma, and odontogenic sarcoma.
-
Cysts
- Inflammatory cysts are a common type and result from inflammation.
- Mandibular buccal bifurcation cysts are less common.
- Paradental cysts are present near teeth.
- Dentigerous cysts surround unerupted teeth.
- Odontogenic keratocysts (OKC) are common and can be aggressive.
- Other types include orthokeratinized cysts, gingival cysts (both newborn and adult), lateral periodontal cysts, botryoid odontogenic cysts, calcifying odontogenic cysts, and glandular odontogenic cysts.
- Nasopalatine duct cysts are non-odontogenic.
Treatment
- Treatment for cysts and tumors depends on the type, location, and severity. -Surgical intervention is often necessary, with enucleation and curettage common procedures.
