Odontoma has been classified as having many kinds of forms or structures since it was first reported in 1821 by Oudet. Here we discuss those forms that have been observed from 1927 to 1984 in Japan. including one of our own recent cases. 1) The cases of compound odontoma, numbering 179, were more frequent than cases of complex odontoma, which numbered 149. 2) Odontoma was observed frequently in the age-group of 10 to 29 years, with no sexual differences. 3) Compound odontoma occurred frequently in the upper anterior teeth, while complex odontoma occurred in the lower molar tooth. 4) Dimensions measured less than 10mm^3 as a rule. (the complex type is usually larger than the compound type.) 5) The number of denticles found was 19 at most. 6) Impacted teeth existed in 45% of all odontoma cases. 7) Our own case was a woman, age 30, with odontoma, dimension 18mm^3 on the upper right anterior, 14 denticles of compound odontoma, and no impacted teeth.
