Ameloblastoma – is the most common odontogenic tumor. It usually occurs in the 4th and 5th decades without a gender predilection. It may arise from the lining of a dentigerous cyst but more often arises independently of impacted teeth. It is characterized by a progressive growth rate and, when untreated, may reach enormous proportions. Early symptoms are often absent, but late symptoms may include a painless swelling, loose teeth, malocclusion, or nasal obstruction. Treatment is with radical surgical resection.

Calcifying Epithelial Odontogenic Tumor – (the Pindorg tumor), this is an aggressive odontogenic neoplasm of epithelial derivation. Most cases are associated with an impacted tooth, and the mandibular body or ramus is by far the most common site. The chief sign is cortical expansion. Pain is usually not a complaint. The treatment methods required to root out the disease.

Adenomatoid Odontogenic Tumor – usually associated with the crown of an impacted anterior tooth, this tumor may arise between tooth roots as well. Painless expansion is often the chief complaint. The maxillary incisor-cuspids are common sites. Treatment is with simple surgical enucleation and recurrence is rare.

Squamous Odontogenic Tumor – is a hamartomatous proliferation of odontogenic epithelium. The maxillary incisor-canine area and mandibular molar area are most commonly involved. Most cases are unifocal and tooth mobility is the usual chief complaint. Treatment is with extraction of the involved tooth and thorough curettage of the lesional tissue.

Calcifying Odontogenic Cyst (Gorlin cyst) – is a tumor-like cyst found in the mandibular premolar region. Intrabony lesions may cause expansion, and teeth remain vital. Enucleation with curettage is the treatment of choice with rare recurrences.
