Dental caries in a group of 20‐year‐olds after previous participation in public child dental health services in Copenhagen, Denmark

The present study was undertaken to investigate the prevalence of dental caries in a group of 20-year-olds who had previously participated in Public Child Dental Health Services. Dental caries was related to social status and preventive vists to the private dentist after termination of school. The study population comprised 389 persons aged 20, out of which 313 (80.5%) were examined clinically and radiographically by one dentist according to standardized criteria. Mean DMFT was 10.4 and mean DMFS 16.7. Differences in relation to sex were not significant. The distribution of subjects according to DMFS was uneven. The 20% with the highest DMFS accounted for about 45% of the total amounts of DS. A consistent pattern with higher mean DMFS in the low social groups was found. Attendance to Regular Youth Dental Service was higher the longer the subjects had been students and higher mean DMFS was found in nonregular attenders. The presence of a high caries risk group is discussed in relation to the dental care system received by the study population.
