Dental Caries in the Adult Population in Finland: I. Prevalence of Dental Caries

Abstract

The aim of this study was to describe the prevalence of untreated dental caries in the adult population aged 30 years and over in Finland according to sex, age, region of living, and socioeconomic status. The level of untreated caries per subject also was studied and population estimates were made for prevalence and level of untreated caries. The representative sample used in this study included 5028 dentate subjects. Data were collected using interviews and clinical examination. The prevalence of untreated caries was 55% in women, and the figure for men was 67%. In eastern Finland the figures for women and men differed significantly. The mean number of decayed teeth was 2.5 per person. Men had more decayed teeth per person than women did. The number decreased significantly with increasing socioeconomic status. The data presented in the study provide a reliable picture of the occurrence of untreated dental caries in Finnish adults and form the basis for further analyses.
