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.
