The Validity of Self‐reported Oral Health Status in the Elderly

Abstract

The validity of self-reported number of teeth was assessed in a random sample of 50 individuals aged 70+ by comparing self-reports in a telephone interview with results of a subsequent in-home examination by a dentist. There were no significant differences between self-report and examination data, nor was there any systematic under- or over-counting of teeth as the actual number of teeth increased. These data support the validity of self-reported dentition.
