Explanatory models for clinically determined and symptom-reported caries indicators in an adult population.
The aim of the present study was to analyze possible indicators of: (i) relative number of decayed and filled teeth, (ii) relative number of decayed teeth, (iii) subjectively reported toothache, and (iv) sensitive teeth, and to find explanatory models for these phenomena. Independent variables from three domains were used: (i) socio-economic factors, (ii) general health and health-related lifestyle, and (iii) dental attitudes and behaviors. The study basis was validated questionnaires from all 50-year-olds in 2 Swedish counties (n = 8888), response rate 71% (n = 6343). For a 20% subsample (58% participation) the DFT and DT were determined by calibrated dentists. Analyses were done with logistic and multiple regression. The variables born outside Sweden, gender, education, shift work, satisfaction with dental care, fear and care utilization were associated with DFT/number of teeth. For DT/number of teeth, the direction of association was reversed for the variables born outside Sweden and gender. Social class, education, general health, and use of tobacco were further covariates. Good oral hygiene gave a lower ratio of DT. For the logistic regression model of toothache, residence in cities and satisfaction with dental care had lower probability for toothache reports, while born outside Sweden, mouth dryness, use of pharmaceuticals, tobacco, fear, and high utilization increased this probability. In general, the association pattern was as could be expected: immigrants, working class, low education, smoking, dissatisfaction with dental treatment and low utilization all appeared as risk factors for both the clinically determined caries indicators, but not necessarily for subjective symptom reports. Only fear of dental treatment showed a consistent positive association with all the indicators.
