Therefore, this cross\u2010sectional study evaluated the validity of the CDC\/AAP self\u2011report questionnaire for periodontitis in a Thai population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The Thai version of CDC\/AAP self\u2010reported questionnaire was developed. Full\u2010mouth periodontal examinations were performed, and periodontitis was diagnosed using CDC\/AAP 2012 or European Federation of Periodontology (EFP)\/AAP 2018 case definition. Association between questionnaire responses and a periodontitis diagnosis was assessed using multiple regression modeling. Several predictive models were constructed and their validity assessed using receiver operating characteristic curves.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study included 250 participants resided in Chiang Mai, Thailand, aged 20\u201382 years, with 83.6% and 84.4% diagnosed with periodontitis based on CDC\/AAP 2012 and EFP\/AAP 2018 case definitions, respectively. CDC\/AAP questions revealed a satisfactory performance in predicting CDC\/AAP\u2010defined severe periodontitis and EFP\/AAP\u2010defined stage III\/IV periodontitis. Additional questions regarding demographic data and periodontal risk factors improved the performance. Reduced model constructed using stepwise regression yielded sensitivity versus specificity of 57.8%\u00a0versus 84.0% and 79.4%\u00a0versus 81.4% for predicting CDC\/AAP\u2010defined severe periodontitis and EFP\/AAP\u2010defined stage III\/IV periodontitis, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The questionnaire in Thai version demonstrated better performance in predicting advanced stages of periodontitis when combined with demographic variables and periodontal risk factors.

Efforts have been made to assemble tools to ease the process, and questionnaires are an auspicious tool. This study aimed to validate the self\u2010reported questionnaire developed by the US Centers for Disease Control and Prevention in collaboration with the American Academy of Periodontology for predicting periodontal disease in the Thai population. The validity of the questionnaires was assessed by comparing the self\u2010reported responses to the data collected through a full\u2010mouth examination by a third\u2010year resident from the Periodontology Residency Training Program. In our study, questions related to signs of the disease showed promising validity as a predictive variable for periodontitis, especially its severe form, and the questionnaires performed better when used together with other questions, such as age and education level.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jper.24-0707","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T18:46:12Z","timestamp":1761763572000},"page":"1413-1431","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Validity of a self\u2010reported questionnaire for periodontal status in a Thai population"],"prefix":"10.1002","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9410-0791","authenticated-orcid":false,"given":"Chutinun","family":"Chaiwut","sequence":"first","affiliation":[{"name":"Department of Restorative Dentistry and Periodontology Faculty of Dentistry Chiang Mai University  Chiang Mai Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7927-1425","authenticated-orcid":false,"given":"Chidchanok","family":"Ruengorn","sequence":"additional","affiliation":[{"name":"Pharmacoepidemiology and Statistics Research Center Faculty of Pharmacy Chiang Mai University Chiang Mai Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6623-6735","authenticated-orcid":false,"given":"Panwadee","family":"Bandhaya","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry and Periodontology Faculty of Dentistry Chiang Mai University  Chiang Mai Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,29]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12104"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.12732"},{"key":"e_1_2_10_4_1","first-page":"72","article-title":"Prevalence of periodontal disease, its association with systemic diseases and prevention","volume":"11","author":"Nazir MA","year":"2017","journal-title":"Int J Health Sci"},{"key":"e_1_2_10_5_1","volume-title":"Report on the ninth National Oral Health Survey, Thailand 2023","author":"Bureau of Dental Health","year":"2024"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034511402080"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2011.110015"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060212"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034513505621"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060435"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060199"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060344"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060481"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1539\/joh.L8108"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.070134"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.12899"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/JPER.19-0292"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1590\/1807-3107bor-2022.vol36.0060"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12903-019-0784-7"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-021-03952-2"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-93965-4"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.13484"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2017.160678"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2012.110664"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/JPER.17-0721"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.13462"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/JPER.21-0276"},{"key":"e_1_2_10_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/JPER.23-0088"},{"key":"e_1_2_10_29_1","unstructured":"DhandNK KhatkarMS Statulator: an online statistical calculator. sample size calculator for estimating a single proportion2022.
