- OBJECTIVE: To investigate the dental health of Swedish children and adolescents with reference to age, gender and residence.MATERIAL AND METHODS: Electronic dental records from 300,988 3-19-year-olds in one Swedish region were derived in a cross-sectional study in years 2007-2009. The DMFT system was used. Age was categorized into 3-6/7-9/10-12/13-15/16-17/18-19-year-olds and residence into 'metropolitan', 'urban' and 'rural' areas. ANOVA, generalized linear regression models and Fisher's exact test were used.RESULTS: Among 7-9-year-old children, nine out of 10 were free from fillings and manifest caries, while for 18-19-year-olds; this proportion was one third. Girls (18-19-year-olds) had a significantly lower risk of caries compared to boys of the same age, RR for the DT index = 0.83 (95% CI = 0.81-0.85). This pattern was reversed in 7-12-year-old children. Children and adolescents in metropolitan and urban areas had significantly more caries than subjects in rural areas, for instance the RR for the DT index in metropolitan 7-9-year-olds was 2.26 (95% CI = 2.11-2.42) compared to their rural counterparts.CONCLUSIONS: In the permanent dentition, the overall pattern revealed that girls ≤ 12 years had a higher risk of caries, while adolescent girls had a lower risk of caries, both compared with boys of corresponding ages. Living in an urban or metropolitan area entailed a higher risk of caries than living in a rural area. A greater occurrence of dental caries in adolescents than in children was confirmed. The findings should have implications for planning and evaluation of oral health promotion and disease prevention activities.

- The study aimed to explore associations between multiple socioeconomic factors and dental caries experience in Swedish children and adolescents (3-19 years old). Electronic dental records from 300,988, in a Swedish region (97.3% coverage) were collected using the DMFT indices (decayed, missing, filled teeth: dependent variables). Socioeconomic status (SES) data (ethnicity, wealth, parental education, and employment) for individuals, parents, and families were obtained from official registers. Principal component analysis was used to explore SES data. Scores based on the first factor were used as an independent aggregated socioeconomic variable in logistic regression analyses. Dental caries experience was low in the participants: 16% in 3- to 6-year-olds (deft index: decayed, extracted, filled teeth) and 47% in 7- to 19-year-olds (DFT index). Both separate and aggregated socioeconomic variables were consistently associated with the dental caries experience irrespective of the caries index used: the crude odds ratio (OR) for having at least 1 caries lesion in 3- to 6-year-olds (deft index) in the lowest SES quintile was 3.26 (95% confidence interval [CI] 3.09-3.43) and in ≥7-year-olds (DFT index) OR 1.80 (95% CI 1.75-1.84) compared with children in the 4 higher SES quintiles. Overall, associations were stronger in the primary dentition than in the permanent dentition. Large SES models contributed more to explaining the caries experience than slim models including fewer SES indicators. In conclusion, socioeconomic factors were consistently associated with dental caries experience in the children and adolescents both as single factors and as multiple factors combined in an index. Socioeconomic inequalities had stronger associations to caries experience in young children than in older children and adolescents.
