Perceptions of the natural dentition in the context of multiple variables

Abstract

Perceived oral health status has been shown to be associated with a variety of single clinical and self-reported indicators of oral health and oral health-related behaviors. A behavioral model is utilized which hypothesizes that perceived condition of natural teeth is predicted by multiple factors, including individual demographic and enabling characteristics, other health perceptions and orientations, actual levels of diseases and conditions, and self-defined need for treatment. The data are from the clinical examination and adult questionnaire of Phase 1 (1988-1991) of the Third National Health and Nutrition Examination Survey, which is based on a stratified multistage probability sample to produce nationally representative data for the civilian, non-institutionalized US population. Multivariate hierarchical regressions were used to assess perceived condition of natural teeth in two groups of dentate adults (those with a dental visit during the past 12 months, and those with a less recent dental visit). Self-defined treatment need made a significant, non-trivial contribution after other variables had been controlled. In both subpopulation models, the perception of general health and epidemiological indicators of oral health status were also significant factors. Socio-economic indicators did not contribute significantly in either regression. Understanding components of overall perceptions of oral health moves us closer to understanding oral health behaviors and oral-health-related quality of life.
