[Correlations between the presence of a mesiodens and position abnormalities, diastemas, and eruption disturbances of maxillary frontal teeth].

A mesiodens is often diagnosed coincidentally during a radiological examination. However, a mesiodens may also be diagnosed in relation to a clinically identified central diastema and an eruption disturbance, or a rotation of a central incisor. In this study of a group of 162 children and adolescents varying in age from 4 to 18 years, with a mesiodens, the frequency of position abnormalities, diastemas, and eruption disturbances of the maxillary frontal teeth was registered retrospectively. One or more of these complications was diagnosed in 72% of the patients. Usually, removal of the mesiodens in children and adolescents results in spontaneous recovery of the complications. Early diagnosis and early treatment are therefore important.
