Abstract
The purpose of this study was to record the caries status in children attending public primary schools in Nairobi. The sample comprised 513 children, 262 aged 68 years and 251 aged 13–15 years. The children were drawn from six randomly selected schools in the city. Clinical examination was carried out in a room with natural daylight, using the WHO (1977) criteria. Fifty-four per cent of the 6-to 8-year-olds and 50% of the 13-to 15-year-olds were caries-free. The mean dmft in the 6-to 8-year-olds was 1.7, and the mean dmfs was 3.5. The mean DMFT in the 13-to 15-year-olds was 1.8, and the mean DMFS was 2.9. The d- and D-components dominated and were mainly located in the occlusal surfaces. The f-component of the dmft and the F-component of the DMFT comprised 1% and 10%, respectively. There was no statistically significant difference (p > 0.05) in the prevalence of caries between males and females in the younger age group. In the older age group, however, females had a higher (p < 0.05) prevalence than males. In general, the study showed a low caries prevalence in Nairobi children. □ Dental caries; epidemiology; prevalence
