DEVELOPMENTAL CYSTS ✨
1. Dentigerous Cyst:
Most common developmental cyst. Unilocular. Envelops the crown of an unerupted tooth (most common around impacted teeth, especially mandibular third molars)

2. Odontogenic Keratocyst (OKC): Odontogenic cyst with thin, regular lining of parakeratinized squamous epithelium with basal palisading hyperchromatic cells.
3. Lateral Periodontal Cyst : Odontogenic cyst lined by non-keratinizing squamous epithelium.
3. Lateral Periodontal Cyst : Odontogenic cyst lined by non-keratinizing squamous epithelium.
4. Nasopalatine Duct Cyst : Non-odontogenic cyst that arises in the midline of the anterior maxilla in the hard palate.
5. Radicular (Periapical) Cyst :
Inflammatory odontogenic cyst associated with nonvital teeth. Most common cysts of the Jaw!

6. Ameloblastoma :
Benign, intraosseous tumor. Most often in mandible.
Most common odontogenic tumor (excluding odontomas).
7. Central Giant Cell Granuloma :
Benign. Usually females <20yrs. Often in mandible. Localized (but sometimes aggressive) osteolytic lesion.

8. Cementoblastoma :
Calcified cementum-like tissue deposited directly on a tooth root.
9 Odontogenic Myxoma :
Cementoblastoma Benign.
Stellate to spindled cells in abundant myxoid matrix.

10 Odontoma :
Compound odontoma-multiple rudimentary teeth (with dentin,
cementum, enamel, pulp, etc...).
Complex odontoodontoma-irregular mass of tooth components.
