[Teeth condition in children aged 7 years in Warsaw and the province of Warsaw].

Teeth were examined in 180 children aged 7 years of either sex in three randomly selected regions: Warsaw, Sulejówek and Wiazowna community by the routine method in school stomatological offices. The assessment of teeth was done according to the WHO principles. In the studied population 85.3% erupted permanent molars, 71.1% medial incisors, and 29.2% lateral incisors were found. No significant differences were found in the per cent of erupted permanent teeth between these three regions, but the proportion of erupted teeth was greater in girls than boys. The prevalence of caries in the permanent teeth in this population was 25%, and again no difference of this prevalence was found between these three regions, but in girls this prevalence was greater than in boys. The DMF index was not different in these regions, but in girls it was twice that in boys (0.6 vs 0.3).
