Studies included those using the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC\/AAP) criteria or the 2017 World Workshop classifications as reference standards and reporting the diagnostic accuracy of self\u2010reported questionnaire items. The validity of the eight\u2010item questionnaire developed by the CDC\/AAP was assessed by analysing the proportion of answers, and bias was evaluated using the QUADAS\u20102 tool. Owing to the limited number of studies using the 2017 World Workshop classifications, the quantitative synthesis was restricted to those using the CDC\/AAP criteria. Sensitivity, specificity, diagnostic odds ratio (DOR) and 95% confidence intervals (CIs) were calculated for total periodontitis (including mild, moderate and severe cases), moderate\u2010to\u2010severe periodontitis and severe periodontitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Totally, 23 studies (from 22 articles) were included in the systematic review, with 16 studies (from 15 articles) eligible for meta\u2010analysis. The \u2018Don't know\/Refused\u2019 option across the eight items of the CDC\/AAP questionnaire ranged from 0% to 46.1%, indicating variable comprehension of certain items. Pooled sensitivity and specificity across the questionnaire items ranged from 17% to 82% and from 23% to 97%, respectively. DOR varied from 0.75 (95% CI: 0.54\u20131.03) to 8.01 (95% CI: 2.33\u201327.45).
