The odontoma is a hamartoma[1] of odontogenic origin.[2]

The average age of people found with an odontoma is 14,[3] and the condition is frequently associated with an unerupted tooth.

In 2011; 66% of odontogenic tumors are odontomas (University of Louisville School of Dentistry). 22% of odontogenic tumors are odontomas.[4]

Classification[edit]

There are two types: compound and complex.[5]

  • A compound odontoma still has the three separate dental tissues (enamel, dentin and cementum), but may present a lobulated appearance where there is no definitive demarcation of separate tissues between the individual "toothlets" (or denticles). It usually appears in the anterior maxilla.
  • The complex type is unrecognizable as dental tissues, usually presenting as a radioopaque area with varying densities. It usually appears in the posterior maxilla or in the mandible.
