Patient Data

Age: 40 years
Gender: Male

A radiodense mass 20x9x9mm in the alveolar mandibular bone, with radiodensities similar to dental enamel and dentin. Irregular shape, similar to small denticles. Also, a small odontoma is located in the marginal bone distal to remanent tooth 6.3. Also agenesia of tooth 3.4 and inclusion of 3.4, located on the other side of the medular mandibular bone in the apical zone below tooth 4.3.

Case Discussion

Odontomas are benign tumors of odontogenic origin consisting of enamel, dentine, cementum and pulpal tissue. They possess a slow growth and are asymptomatic. Usually, the patient is evaluated for tooth eruption disturbances, like this case, where two primary teeth are still present in an adult. 

There are two types: compound and complex. The compound is approximately twice as common as the complex. 

Both are mixed odontogenic tumors since they consist epithelial and mesenchymal tissues, which differentiate in enamel, dentin and pulp.
