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

Abstract

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.
