Types of Odontoma
- Compound odontoma consists of four separate dental tissues embedded in fibrous connective tissue.
- Complex odontoma is unrecognizable as dental hard and soft tissues, usually presenting as a radioopaque area.
- Dilated odontoma is an infrequent developmental alteration that appears in any area of the dental arches.
- Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ.
- Ameloblastic fibrodentinoma and ameloblastic fibro-odontoma are types of lesions resembling complex odontomas.

Histopathology of Odontoma
- Odontomas are composed of mixed epithelial and mesenchymal components.
- These components are required for tooth development and produce enamel, dentine, cementum, and pulp tissue.

Presentation of Odontoma
- Odontomas are usually asymptomatic and often found as chance radiographic findings.
- They are commonly detected during childhood and adolescence when teeth do not erupt within the expected timeframe.
- Occasionally, odontomas can erupt into the mouth and cause acute infections resembling dental abscesses.
- Radiolucent flecks develop during the early stage of odontoma development.
- A dense radioopaque mass becomes visible as enamel and dentine form.

Aetiology of Odontoma
- The overall cause of odontomas is unknown.
- They have been associated with local trauma, inflammatory and/or infectious processes, and hereditary anomalies.
- Odontoblastic hyperactivity, mature odontoblasts, and dental lamina remnants (Cell Rests of Serres) have also been implicated.

Treatment of Odontoma
- The most common treatment for odontomas is surgical enucleation.
- Odontomas are well-encapsulated, allowing for separation from the surrounding bone.
- If left untreated, odontomas can result in the formation of a dentigerous cyst.
