Abstract

Objectives: Workplaces are suitable for screening for periodontal disease effectively. However, the majority of workplaces do not have a screening program. One possible reason may be that pocket probing, which is commonly used for the screening, needs qualified examiners and is time-consuming. In this study, the validity of a self-reported questionnaire was assessed for screening of periodontitis in 50-to 59-yr-old male employees in Japan. Methods: A total of 250 people were asked to complete a self-administered questionnaire regarding signs and symptoms of periodontal disease, and experience of periodontal treatment, followed by a clinical examination by a dentist. Subjects with at least one tooth having a clinical attachment loss of 7 mm or more were defined as periodontitis patients. Results: Thirteen percent of the subjects were diagnosed as having periodontitis. Logistic regression selected 4 questions, "Are you a current or past smoker?", "Have your gums bled recently?", "Do you think that you can see more roots of teeth than in the past?", and "Have you ever been told that you need periodontal or gum treatment?" as potential predictors of periodontitis. When subjects with at least 3 "yes" responses to the 4 questions were separated from the others, the subjects with periodontitis were separated most effectively (showing the highest sensitivity + specificity: 1.524) from those without. The area under the receiver operating characteristic curve was 0.81. Conclusions: These results suggest that the self-reported questions are useful for screening of periodontitis in 50-to 59-yr-old Japanese workers.
