To investigate the practical value of using questionnaires (self perceived assessment) as compared with clinical examinations (normative assessment) and to evaluate the role of socioeconomic status and implications of the results in understanding the public perception of oral health.
This was a cross-sectional single-blind study. A purposive sample of 860 bank employees of Belgaum city, India, were asked to fill in a close-ended questionnaire inquiring about their socioeconomic status, dental, periodontal health levels and treatment needs. Clinical examinations, employing the WHO dentition status and Community Periodontal Index, were performed to determine normative status and needs. Perceived and normative assessments were compared for sensitivity, specificity, positive and negative predictive values.
The kappa values ranged from 0 (treatment needs) to 0.67 (for prosthesis). The degree of agreement with the following kappa values and sensitivity was seen in filled teeth (0.52, 60%), missing teeth (0.62, 83.8%), and prosthesis (0.67, 58.3%). However, the disagreement was seen with all other questions with average kappa value of 0.20.
Self-assessment questionnaires were of low value in evaluating dental, periodontal health status and treatment needs in the study subjects. Findings reflect a low level of awareness that may influence care-seeking behavior and socioeconomic status has a clear role to play in dental health perception.
探讨使用问卷调查（自我感知评估）与临床检查（规范评估）相比的实用价值，并评估社会经济地位的作用以及结果在理解公众口腔健康认知方面的意义。
这是一项横断面单盲研究。选取印度贝尔高姆市860名银行员工作为有目的的样本，要求他们填写一份封闭式问卷，询问其社会经济地位、牙齿、牙周健康水平及治疗需求。采用世界卫生组织牙列状况和社区牙周指数进行临床检查，以确定规范状况和需求。比较感知评估和规范评估的敏感性、特异性、阳性和阴性预测值。
kappa值范围从0（治疗需求）到0.67（假牙）。在补过的牙齿（0.52，60%）、缺失牙（0.62，83.8%）和假牙（0.67，58.3%）方面，观察到与以下kappa值和敏感性的一致程度。然而，在所有其他问题上存在不一致，平均kappa值为0.20。
自我评估问卷在评估研究对象的牙齿、牙周健康状况和治疗需求方面价值较低。研究结果反映出认知水平较低，这可能会影响就医行为，且社会经济地位在口腔健康认知方面有明显作用。
