Found very little literature regarding this topic. many of these points are concluded by myself.

COMPARE BETWEEN ODONTOGENIC
& NON-ODONTOGENIC TUMORS
X

2. Odontogenic tumors
Are pathologic outcomes from tissue elements that are part of the tooth-forming
apparatus. These tumors occur exclusively in the bones of the jaw particularly around
the teeth-bearing segments.
Etiology: Unknown, usually associated with unerupted/impacted tooth.
Non-Odontogenic tumors
Tumors or neoplasms are new growths of tissues arise in the oral cavity as in other
parts of the body. These new growths may be of epithelial tissue
or mesenchymal tissue origin.
Etiology: Chronic irritation, Tobacco, Alcohol, Syphilis, Infections, Sun light exposure, and the Ionizing radiation.

3. X Non-Odontogenic tumors Odontogenic tumors
Diagnosis: Clinically and Radiographically
Radiographically,
Palpable in some cases.
Site: Oral cavity and lips. Jaws. Usually in the mandible.
Mobility: Movable. Fixed.
Biologic activity:
A potential full range of biologic activity,
they may show intratumoral regressive
changes such as Hemorrhage and Necrosis.
Narrow zone of transition.
Low biologic activity.
Metastasis:
Potential to produce regional lymph
node disease or manifest perineural spread or
distant metastases.
Low.
Effect on
surrounding structures:
Little or No Bone expansion.
(Limited to soft tissue)
Bone expansion.
Tooth resorption.

5. Overall comparison:
▪ Non-Odontogenic tumors are more common than Odontogenic tumors and have a wide variety of lesions.
▪ 90% of oral malignant neoplasms are Non-Odotogenic.
▪ Odontogenic tumors have higher chances of re-occurrence.
▪ Less post-treatment complications in Non-Odontogenic tumors.
▪ Basal cell carcinoma/ epithelioma is the most common skin cancer and the most common of all
cancers can occur on the lip.
