Adults' estimated prevalence of healthy behavior in society and self-reported oral health status and behaviors.

Abstract

To assess Mashhad residents' self-perceived oral health level (OHL) and behaviors in relation to their perceptions of those of their fellow citizens. Cross-sectional telephone survey of 384 individuals recruited from communication centers. The interviews followed a validated Persian schedule with three main sections: 1) background information, 2) questions regarding self-reported OHL, and 3) questions regarding respondents' perceptions of the OHL of their fellow citizens. Participants' mean self-rated OHL and tooth brushing frequency were higher than those of their fellow citizens. The correlation between self-reported and the estimated decayed and missing (DMT) was highest in the middle and lowest in the upper classes. Perceptions of the self- and others' OHL and DMT were positively correlated, with the latter being more so. Education level, age, and tooth brushing frequency affected self-perceived OHL and DMT. Participants' perceived OHL could be explained by their estimation of the general population's oral health. These findings suggest that social norm interventions could nudge improving oral health behaviors.
