Supernumerary and congenitally missing primary teeth in Finnish children. An epidemiologic study.

The prevalence of supernumerary and congenitally missing primary teeth was studied in a sample of 1141 children aged 3-4 years. The prevalence of supernumerary teeth was 0.4%; all the supernumerary teeth being located in the maxillary incisor area. The prevalence of congenitally missing teeth was 0.9%; seven of the missing teeth being maxillary and four mandibular lateral incisors. The differences in the prevalence of the anomalies between the sexes were not statistically significant. Of the fifteen children with a numerical variation of primary teeth, four developed similar anomalies in the permanent dentition.

Epidemiologic study of joined primary teeth in Finnish children.

The frequency of germinated and fused primary teeth was studied in a sample of 1141 Finnish children aged 3-4 years. The prevalence was 0.7%. All the joined teeth were found in the anterior area of the mouth. In seven cases the diagnosis was a fusion of two separate teeth, and in one case it was a germination of a single tooth. A correlation between joined teeth in primary dentition and numerical variations of teeth in permanent dentition was noted in three cases.
