Abstract

Aim To externally validate a previously developed time‐ and cost‐effective screening tool for screening subjects with different periodontal conditions by combining various questionnaires, demographic data and lifestyle factors, providing a reliable basis for future efforts to promote public awareness of oral/periodontal health and early periodontal care. Methods The study consisted of a self‐administered questionnaire and a full‐mouth periodontal and radiographic examination. External validation was conducted using a representative cohort systematically and randomly selected from the general population of Hong Kong. A modified questionnaire originally proposed by the Centers for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP) was given to participants, and the results were tested against the periodontal case definition based on the 2017 World Workshop Classification of Periodontal Diseases. Accuracy was analysed by multivariate logistic regression, and the area under the receiver operating characteristic curve (AUROC) was calculated. Results A total of 384 subjects participated in this validation study, including individuals with periodontal health (6.2%), gingivitis (19.3%), Stage I/II periodontitis (19.3%) and Stage III/IV periodontitis (55.2%). The screening model, which integrated the CDC/AAP questionnaire with demographic and lifestyle factors, showed the best performance in detecting both periodontitis and severe periodontitis. For periodontitis detection, the model achieved an AUROC of 0.888, with a sensitivity of 91.1% and specificity of 90.0%. For Stage III/IV periodontitis, it showed an AUROC of 0.899, with a sensitivity of 88.8% and specificity of 77.2%. Conclusion This externally validated model demonstrates acceptable accuracy in identifying periodontitis patients in independent populations, supporting its potential applicability across diverse community settings.

自我报告牙周病诊断准确性的外部验证试验

目的通过结合各种问卷调查、人口统计数据和生活方式因素，从外部验证先前开发的具有时间和成本效益的筛查工具，用于筛查不同牙周状况的受试者，为未来努力提高公众对口腔/牙周健康和早期牙周保健的认识提供可靠的基础。方法：采用自行填写的调查问卷和全口牙周及x线检查。外部验证采用有代表性的队列系统和随机从香港的一般人群中选择。研究人员向参与者发放了一份由美国疾病控制与预防中心/美国牙周病学会（CDC/AAP）最初提出的修改后的问卷，并根据2017年世界牙周病研讨会分类的牙周病例定义对结果进行了测试。采用多元logistic回归分析准确率，计算受试者工作特征曲线下面积（AUROC）。结果共有384名受试者参与了本验证性研究，包括牙周健康（6.2%）、牙龈炎（19.3%）、I/II期牙周炎（19.3%）和III/IV期牙周炎（55.2%）。该筛查模型将CDC/AAP问卷与人口统计学和生活方式因素相结合，在检测牙周炎和重度牙周炎方面表现最佳。对于牙周炎的检测，该模型的AUROC为0.888，灵敏度为91.1%，特异性为90.0%。对于III/IV期牙周炎，AUROC为0.899，敏感性为88.8%，特异性为77.2%。结论：该外部验证模型在独立人群中识别牙周炎患者具有可接受的准确性，支持其在不同社区环境中的潜在适用性。

期刊介绍： Journal of Clinical Periodontology was founded by the British, Dutch, French, German, Scandinavian, and Swiss Societies of Periodontology. The aim of the Journal of Clinical Periodontology is to provide the platform for exchange of scientific and clinical progress in the field of Periodontology and allied disciplines, and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope. The Journal publishes original contributions of high scientific merit in the fields of periodontology and implant dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, and the comprehensive rehabilitation of the periodontal patient. Review articles by experts on new developments in basic and applied periodontal science and associated dental disciplines, advances in periodontal or implant techniques and procedures, and case reports which illustrate important new information are also welcome.
