Dental conditions in middle-aged and older people in Denmark and Sweden: a comparative study of the influence of socioeconomic and attitudinal factors.

In 1998-99 two parallel questionnaire studies were performed in Denmark and Sweden. In Denmark the age group was 45-69 years and in Sweden 55-79 years. One aim was to study the influence of socioeconomic and attitudinal factors on dental status in the two countries. For the comparable age groups 55-69 years there was a striking difference in dental conditions between the countries. In Sweden, 72% had either all teeth remaining, missing teeth replaced by fixed prosthodontics, or only one or two single missing teeth not replaced. The corresponding figure for Denmark was 44%. Among Danes, 34% were wearing removable denture(s) or were edentulous in one jaw or both jaws, compared with 15%, among Swedes. In logistic regression models, higher income and longer education were significantly associated with the best dental status categories in Denmark but not in Sweden. In the model with wearing removable denture(s) as the dependent variable, lower income and lower education level showed a significant influence for the Danes. In Sweden, lower income showed a significant influence but education level was insignificant. In both Denmark and Sweden, a positive attitude toward the importance of dental appearance was associated with an increased risk of wearing removable denture(s).
