- 107 individuals, randomly selected from the County of Göteborg and Bohuslän, all born in 1970 were followed regarding the dental care received 1987-1989. The records of each individual from the actual time were collected and information on diagnosis and treatment measures was gathered. Radiographs from the actual time were studied by one of the authors. Sixty-two per cent of the adolescents had been examined and treated all 3 years. Six percent had not been seen at all. The sample was divided into three groups depending on the patient's DFSa value at the examination the first year. This classification appeared to correlate well with caries development in the following years. One-fourth of the sample was responsible for the major part of the non-attendance and late cancellations. The dental health of these subjects was below average, and non-attendance seemed to be a further risk factor. The preventive measures undertaken during the study appeared to correlate poorly with the actual situation of the patient and the presence or absence of potential risk factors.

- The aim was--in a longitudinal respect--to study whether 15-year-old children, in caries-free groups, and groups with high frequency of carious lesions, had a stable caries development from 15 to 19 years of age, when they left the organised Public Dental Care. Caries index values were analysed for the period 1986/7-1990/1 for patients born 1971-72 and residing in Göteborg. The groups of caries-free children seemed to be stable in their dental health in about 60-70% according to the prevalence indices used; and about 80% according to the incidence index DS-a. The caries prevalence index mean values of the 15-year-old patient groups with high frequencies of lesions showed between 1.5 to 3.5 percentile units higher mean values when the individuals were 19 years of age. However, the corresponding caries incidence index values were as low as half the size, indicating a possible treatment effect of the caries prevention programme used. Related to the DFS-a index, the 20% groups with the highest caries index values were registered for about 80% of all approximal lesions, of special interest for dental care costs.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present study was to compare registered data of caries prevalence and incidence from cross-sectional studies of specified age groups with the corresponding caries data from cohorts of individuals receiving dental health service from the same dental clinic during the years studied. The study covered two 15-19-year groups, who had been offered complete dental care from three years of age in the City of Göteborg for the time periods 1986/7-1990/1. When compared, the longitudinal cohort attempts often gave statistically significant different values to those of the cross-sectional year classes, which should be considered when presenting caries index mean values in dental health reviews. It is not indifferent to choose between longitudinal cohort and cross-sectional year class attempts when searching for dental health treatment effects. Due to the advantages of using longitudinal cohort study methods, and with regard to the differences of the study design used, as pointed out in the study, the use of longitudinal cohort patient material, extracted from cross-sectional epidemiological data bases, could favour analysis of the effects of different preventive dental care programs.
