Aim:

To verify if self-report is a valid instrument to study the clinical oral condition in older people without cognitive deficit.

Methods:

A Cross-sectional study was conducted with 647 older people from the community, without cognitive deficit, living in Campinas, Brazil. A self-report questionnaire assessing the presence or absence of teeth (edentulism) and use of complete denture was applied, identifying the location of the denture, whether in the upper and/or lower arch. In the same session oral clinical exams were performed, considered the gold standard. The self-report validation was performed by calculating sensitivity, specificity, predictive values, odds ratios and Kappa agreement.

Results:

There were high percentages of sensitivity (95–99%), specificity (84–97%), positive (81–97%) and negative (95–98%) predictive values, obtaining an elevated level of confidence and quality intrinsic value of self-report. Agreement with the clinical examination was excellent for all variables (greater than 0.80). The likelihood ratios showed compelling evidence that with self-report an edentulous individual (+LR 32), non-edentulous (-LR 0.06) and absence of complete denture (-LR 0.01) could be correctly identified, with moderate evidence to identify the presence and location of complete denture use (+LR 6.5 to 6.9).

Conclusion:

Self-report is a valid instrument to study the clinical oral condition in the older people of the community
