The clinical and radiographic features of 1,171 mesiodenses were studied with
periapical radiograms and/or pantomograms in 942 persons visited the Department of
Oral Radiology, School of Dentistry, Kyung Hee University during January 1980 to
December 1989.
The obrained results were as follows :
1. The incidence of mesiodens was higher in males (75.4%) than in females (24.6%).
2. In number of mesiodenses per individual, a single mesiodens was found to be
75.9%, 2-mesiodenses to be 23.8%, and 3-mesiodenses to be 0.2%.
3. In mesiodenses according to erupted and impacted status, the erupted mesiodens
was found to be 16.5%, the impacted mesiodens in the interdental alveolar bone to be
66.6%, and in the region below root apex to be 16.9%.
4. In impacted mesiodenses according to direction of tooth crown, the inverted
impaction was found to be 68.8%, the vertical impaction to be 15.1%, and the angulated
impaction to be 16.1%. Among the impacted mesiodenses, a palatally located impaction
was 81.5%, a middle 4.9%, and a labially 7.6%.
5. In mesiodenses according to shape of the tooth crown, a incisor-like type was
found to be 1.6%, a canine-like type to be 6.8%, a conical type to be 79.2%, and a
tuberculated type to be 12.4%.
6. In effect of mesiodens on adjacent tooth, non-specific influences were found to be
73.4%, crowding to be 0.3%, diastema to be 11.8%, rotation to be 5.7%, delayed eruption
to be 3.8%, root resorption to be 2.6%, and dentigerous cyst to be 2.4%.
