Abstract:

It aims to evaluate the association between dental appearance and Oral Health Related Quality of Life. Fifteen primary care services with dental services were selected in Porto Alegre, Brazil. Individuals were interviewed from a random sampling of households in the catchment area of the health centres. The outcome was having an OHIP14 score >0 (any impact). The main exposures included self-reported tooth colour and position, perception of oral health and concern with dental aesthetics. Data were analysed with stepwise logistic regression. Of 1943 individuals contacted, 433 used public dental services in the last year. Seventy-three percent had some impact on quality of life, 35.2% and 47.5% reported stained and crowded teeth, respectively. Also, 22.2% had already tried bleaching their teeth. Individuals concerned with colour were 2.56 times (95% CI: 1.34-4.89) more likely to report any impact after adjusting for number of teeth, smoking and education. Concerns about tooth position, reporting stained or crowded teeth, age, sex and income were not significant (p>0.30). There is a direct and independent association between concerns with tooth colour and quality of life. The effect of tooth colour on quality of life may be mediated by individuals’ perceptions of aesthetics.
