The purpose of this study was to ascertain whether questionnaires can be used to replace clinical surveys by comparing normative and perceived caries status and treatment needs in a sample of adults living in East London, UK.
A cross-sectional study was conducted in two stages: a structured interview inquired about perceived dental caries status and treatment needs, and dental examinations were performed to determine oral health status and normative treatment needs. Perceived and normative assessments were compared for overall proportions, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), using the dental examination as a gold standard.
Of 139 people examined, 122 were dentate. The PPVs for perceived caries and treatment need were 0.58 and 0.67, respectively. Overall agreement was 65.4 percent for the presence of caries and 64.7 percent for the presence of treatment need. However, no net error was found between the proportions of participants with decay, and a small net error (7.4%) was found between perceived and normative treatment need.
Self-assessment is not useful to assess individual dental treatment need, but is of possible value in assessing the needs of adult communities.
本研究旨在通过比较英国东伦敦成年人群样本中龋齿的规范状况与自我认知状况以及治疗需求，来确定问卷调查是否可用于替代临床检查。
分两个阶段进行横断面研究：通过结构化访谈询问龋齿的自我认知状况和治疗需求，并进行口腔检查以确定口腔健康状况和规范的治疗需求。以口腔检查作为金标准，比较自我认知评估和规范评估在总体比例、敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）方面的差异。
在接受检查的139人中，122人有牙齿。自我认知的龋齿和治疗需求的PPV分别为0.58和0.67。龋齿存在情况的总体一致性为65.4%，治疗需求存在情况的总体一致性为64.7%。然而，在有龋齿的参与者比例之间未发现净误差，而在自我认知和规范的治疗需求之间发现了较小的净误差（7.4%）。
自我评估对于评估个体的牙科治疗需求并无用处，但在评估成年人群体的需求方面可能具有一定价值。
