Validity of a Questionnaire for Periodontitis Screening of Japanese Employees

Abstract

Validity of a Questionnaire for Periodontitis Screening of Japanese Employees: Tatsuo YAMAMOTO, et al. Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesObjectives: 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. (J Occup Health 2009; 51: 137-143)

Prediction of Periodontitis Occurrence: Influence of Classification and Sociodemographic and General Health Information

“…AUC observed in this study was close to that previously reported in a national survey, 24 but not as high as stated previously 47 , 48 . Some factors might have influenced the results: 1) low prevalence of PD ≥4 mm at age 24 years as severity of periodontal conditions is directly related to AUC increase; 24 2) recording each periodontal condition for tooth and non‐tooth sites for calculus, BOP, and, most importantly, only presence or absence of PD ≥4 mm, leading to loss of information at age 24 years; and 3) periodontal disease being a non‐linear chaotic process, especially in population‐based studies with large intrinsic variations, such as genetic factors and lifestyle (e.g., smoking and nutrition) 49 .…”

Self‐report assessment of severe periodontitis: Periodontal screening score development

“…Yamamoto et al. () also proposed an equation to identify periodontal patients based on four self‐report items; however, this score was validated in a highly selected population of 50‐ to 59‐year‐old men receiving a partial mouth periodontal examination and applying a case definition exclusively based on CAL. Wu et al.…”

“…Within the past decade, self‐report questionnaires for the assessment of periodontal diseases have appeared in the literature (Blicher, Joshipura, & Eke, ; Cyrino, Miranda Cota, Pereira Lages, Bastos Lages, & Costa, ; Dietrich et al., ; Eke et al., ; Genco, Falkner, Grossi, Dunford, & Trevisan, ; Gilbert & Litaker, ; Slade, ; Taylor & Borgnakke, ; Wu, Weng, & Lin, ; Yamamoto et al., ; Zhan et al., ). The majority of the questionnaires were developed in English‐speaking countries.…”

“…Its use allows differentiating healthy individuals from individuals with periodontal diseases with acceptable levels of sensitivity and specificity (Blicher et al, 2005). Other attempts have been made to develop self-report measures for periodontal diseases in Portuguese, German, Chinese, Japanese, and Arabic languages and some authors proposed a periodontal score or scale to identify diseased individuals (Cyrino et al, 2011;Dietrich et al, 2005Dietrich et al, , 2007Khader, Alhabashneh, & Alhersh, 2015;Wu et al, 2013;Yamamoto et al, 2009;Zhan et al, 2014). To date, no self-report questionnaire or score has been developed or validated to be used as a screening tool in French-speaking populations.…”
