Abstract:
Objectives:Clinical examination is considered the gold standard for monitoring periodontal disease. However, it requires significant resources. Self-reported assessment serves as a useful method for screening periodontal diseases in different cohorts. We aimed to evaluate the validity of a selfreported questionnaire for the surveillance of periodontal disease among Korean adults.
Methods:The participants were 120 patients aged ≥19 years old who were examined using the community periodontal index. The questionnaire comprised 10 questions, translated from an English-version, that was used to identify periodontitis. The predictiveness of the measures from the self-reported questions was assessed by multivariable logistic regression modeling using the area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity.
Results:For item 3, “Have you ever had treatment for gum disease, such as scaling and root planning”, the adjusted odds ratio was 4.65; 95% confidence interval, 1.22-17.67; and AUROC, 0.82. The sensitivity and specificity of this item were, 0.93 and 0.42, respectively. In Kendall’s Tau-b correlation analysis, items 1 (“Have gum disease”) and 10 Periodontal treatment and surgery under anesthesia”) had the strongest correlations with item 3, with correlation coefficients of 0.48 and 0.42, respectively. A model combining items 1, 3, and 10, adjusted for demographic variables, resulted in an AUROC of 0.86, sensitivity of 0.86, and specificity of 0.26.
Conclusions:An adapted Korean version (“Have gum disease”, “Treatment for gum disease, such as scaling and root planning”, and “periodontal treatment under anesthesia”) of the self-reported questionnaire demonstrated its capacity for epidemiological surveillance of periodontal disease in this study cohort.
