Occurrence and distribution of caries in 6-year-old children in Blekinge, Sweden.

: Community dentistry in Blekinge aims at age-specific levels of dental health. For 6-year-old children the goal is that > 65 percent will have dmft = 0 in the year 2000. At present there is no study on dental health in 6-year-olds in Blekinge. The aims of the present study are to establish baseline epidemiological data on dental caries in the county of Blekinge, expressed as dentin lesions and enamel lesions, to analyse these data and to formulate program oriented planning of dental care for pre-school children to achieve the dental health goal for the year 2000. The material comprised a random sample of 213 children. The sample was drawn from the population register for children living in the county of Blekinge. A clinical investigation was performed by one of the authors and was completed with bite-wing radiographs whenever the proximal surface could not be inspected clinically. In addition the parents were asked questions about tooth-brushing and use of fluoride tablets. Fifty-six percent of the children had filled lesions and manifest lesions (dfs), 65 percent had enamel caries lesions (dsi) and 42 percent had manifest lesions (ds). Fifty-three percent had dmft > 0. The finding of initial lesions in 65 percent of the children indicates that caries prevalence is greatly underestimated. Together with poor oral hygiene, this means an increase in the risk of caries progression. The pattern of dental health was very skewed among the children; 23 percent had between 5 and fourteen decayed or filled teeth and 11 percent had from 5 to 23 manifest lesions. Clinics in Blekinge have had different strategies for preventive dental care. In 1997, however, all the public dental service clinics in Blekinge, adopted a uniform program for child dental care, focusing on primary prevention and risk assessment for each individual.
