Determinants of dental treatment avoidance: findings from a nationally representative study

BACKGROUND: Oral health care of older adults is of rising importance due to ongoing demographic changes. There is a lack of studies examining the determinants of dental treatment avoidance in this age group. Therefore, the objective of this study was to identify those determinants. METHODS: Cross-sectional data were drawn from the second wave (year 2002) of the German Ageing Survey which is a population-based sample of community-dwelling individuals ≥ 40 years in Germany (n = 3398). Dental treatment avoidance was quantified using the question “Did you need dental treatments in the past twelve months, but did not go to the dentist?” [no; yes, once; yes, several times]. Socioeconomic and health-related determinants were adjusted for in the analysis. Multiple logistic regressions were performed. RESULTS: In terms of need, 6.7% of individuals avoided dental treatment in the preceding twelve months. Multiple logistic regressions revealed that dental treatment avoidance was associated with younger age (total sample [OR 0.978; 95% CI 0.958–0.998] and men [OR 0.970; 95% CI 0.942–0.999]), unemployment (total sample [OR 1.544; 95% CI 1.035–2.302] and men [OR 2.004; 95% CI 1.085–3.702]), lower social strata (women [OR 0.814; 95% CI 0.678–0.977]), increased depressive symptoms (men [OR 1.031; 95% CI 1.001–1.062]), and increased physical illnesses (total sample [OR 1.091; 95% CI 1.006–1.183] and men [OR 1.165; 95% CI 1.048–1.295]). The outcome measure was not associated with income poverty, marital status and physical functioning. CONCLUSIONS: The present study highlights the association between dental treatment avoidance and different socioeconomic and health-related factors. These results suggest that it is necessary to promote the importance of dental visits.
