title: Dental odontomas: a retrospective study of 104 cases.
abstract: An odontoma refers to any tumor of odontogenic origin. Three distinct types of odontomas have been distinguished in the dental literature: complex, compound, and ameloblastic fibro-odontoma. Odontomas are usually associated with overly retained primary and unerupted permanent teeth. The exact etiology of odontomas is unknown, but local trauma, infection, inheritance, and genetic mutation have been postulated as possible causes of odontomas. Studies have found that males are more likely than females to have odontomas, with most frequent occurrence in the second decade of life. One hundred four biopsy reports with a diagnosis of odontoma were analyzed for age, race, gender, location, pre-operative diagnosis, and postoperative laboratory findings. Most odontomas occurred in the 11-20 age group, with Caucasians predominating. The majority were located in the maxilla, and 85 percent were correctly diagnosed clinically by the attending dentist prior to confirmation by histologic pathology reports of the biopsy specimens. The vast majority were compound odontomas (64.4%) with complex odontomas comprising 31.0% of the total lesions. No ameloblastic fibro-odontomas were diagnosed.
