To validate the level of agreement between self-report and clinical examination for oral conditions and evaluate the effect of sociodemographic conditions on the validity of self-report among women aged 60 and older.
A cross-sectional study was conducted in a social community center for seniors in Southern Brazil. Sociodemographic data (age, level of education, and income) were measured. Participants were interviewed and clinically examined for the number of teeth (DMF-T index) and the use of dental prostheses. The self-reported number of teeth in each arch and the use of dental prostheses were gathered through interviews. The level of agreement was estimated using the observed agreement, Kappa statistics, sensitivity/specificity (edentulism/prostheses) and Lin's concordance correlation coefficient, and related tests (number of teeth). The validity of the oral conditions was estimated according to sociodemographic information.
Ninety-nine women participated in the study. High levels of agreement were observed for edentulism (97.8%; 95%CI 92.8;99.7; Kappa 0.947) and the use of dental prostheses (97.0%; 95%CI 91.3;99.4; Kappa 0.922). In both conditions, despite achieving similar concordance correlation coefficients (ranging from weak to moderate), the mean number of upper teeth was lower in clinical examination (7.1 ± 5.2) compared with self-reported (8.6 ± 3.6), while the opposite was observed for lower teeth (clinical examination: 9.1 ± 3.4; self-reported: 6.6 ± 5.3). Larger differences were found among women of low income and educational levels.
Our findings suggest that the participants' socio-economic position might influence their self-reported number of teeth.
验证自我报告和临床检查在口腔状况方面的一致性水平，并评估社会人口状况对 60 岁及以上女性自我报告有效性的影响。
在巴西南部的一个老年人社会社区中心进行了一项横断面研究。测量了社会人口统计学数据（年龄、教育水平和收入）。通过访谈对参与者进行了采访和临床检查，以了解牙齿数量（DMF-T 指数）和使用牙假体的情况。通过访谈收集自我报告的每侧牙齿数量和使用牙假体的情况。使用观察一致性、Kappa 统计、敏感性/特异性（无牙/假体）和 Lin 的一致性相关系数以及相关测试（牙齿数量）来估计一致性水平。根据社会人口学信息评估口腔状况的有效性。
99 名妇女参加了这项研究。观察到无牙（97.8%；95%CI 92.8%；99.7%；Kappa 0.947）和使用牙假体（97.0%；95%CI 91.3%；99.4%；Kappa 0.922）的高度一致性。在这两种情况下，尽管一致性相关系数（从弱到中等）相似，但临床检查中上颌牙齿的平均数量（7.1±5.2）低于自我报告（8.6±3.6），而对于下颌牙齿则相反（临床检查：9.1±3.4；自我报告：6.6±5.3）。在收入和教育水平较低的女性中，差异更大。
我们的研究结果表明，参与者的社会经济地位可能会影响他们自我报告的牙齿数量。
