- periapical cyst

  • A periapical cyst, also known as a radicular cyst, is inflammatory, develops from a periapical granuloma, and is associated with the root of a tooth.
  • It is most common in the anterior maxilla.
  • It shows a stratified squamous epithelium and fibrous capsule with mixed (mostly acute) inflammation.
  • It is the most common odontogenic cyst, and most common cyst of the jaw.

- keratocystic odontogenic tumor

  • Keratocystic odontogenic tumor (odontogenic keratocyst), is a neoplastic cyst usually in the posterior jaw, lined by parakeratotic epithelium with a hyperchromatic, palisaded basal layer and wavy surface.
  • It is associated with nevoid basal cell carcinoma syndrome / Gorlin syndrome.

- dentigerous cyst ( follicular cyst )

  • It is usually associated with impacted teeth (third molars, maxillary canines).
  • It has stratified squamous epithelium and may or may not be inflamed.
  • It is the second most common odontogenic and jaw cyst, behind periapical cysts.
  • Follicular cyst is another name for a dentigerous cyst.
