Study Notes

  1. Different types of periapical lesions have distinct radiographic features and diagnostic criteria.
  2. Treatment plans for periapical lesions vary based on size and severity.
  3. Buccal bifurcation cysts are not periapical radiolucencies but are included for reference.
  4. Other non-periapical lesions, such as ameloblastomas and odontogenic keratocysts, have distinct clinical presentations and radiographic features.
  5. Adenomatoid odontogenic tumors and calcifying cystic odontogenic tumors are common in younger individuals.
  6. Calcifying epithelial odontogenic tumors have variable radiographic features and a rare risk of malignant transformation.
  7. Nasopalatine duct cysts are the most common non-odontogenic cysts and typically occur in middle-aged males.
  8. Antral pseudocysts are dome-shaped soft tissue masses at the floor of the maxilla.
  9. Surgical ciliated cysts may occur in the maxilla after surgery or trauma.
  10. Massive osteolysis and traumatic bone cysts have distinct clinical presentations and radiographic features.
  11. Different cystic-like lesions can occur in the jaw, with varying clinical presentations and radiographic features.
  12. Aneurysmal bone cysts are characterized by rapidly painful swelling and a "blood-soaked sponge" appearance on radiographs.
  13. Central giant cell granulomas can be non-aggressive or aggressive, with well-delineated radiolucencies on radiographs.
  14. Cherubism is a rare condition that causes painless mandibular enlargement in children, and is associated with a gene mutation.
  15. Brown tumors of tertiary hyperparathyroidism can cause jaw tumors, and are related to hypercalcemia.
  16. Osteosarcoma, chondrosarcoma, and primary intraosseous carcinoma can cause ill-defined radiolucencies on radiographs.
  17. Squamous cell carcinoma and metastatic adenocarcinoma can cause "moth eaten" radiolucencies.
  18. Langerhans cell histiocytosis and multiple myeloma can cause multiple "punched out" radiolucencies on radiographs.
  19. Diagnosis of these lesions often involves clinical presentation, radiographs, and biopsy.
  20. Treatment for these lesions can be complicated, and recurrence rates vary.
