It defines periodontal disease based on\nstaging, grading and extent, facilitating a more accurate approach for general dentists and periodontists.\nAim: The aim of this study was to establish the inter-observer agreement and diagnostic accuracy among\nthree groups with different levels of education and experience in dentistry in assigning stages, grades and\nextent of periodontitis using the 2017 AAP-EFP classification system. Materials and Method: The study\ninvolved 32 participants divided into three groups: Group 1-dental students (n=12), Group 2-dentists with\nup to 3 years\u2019 experience (n=10), and Group 3-general dentists with more than 4 years\u2019 clinical experience\n(n=10). Twelve periodontitis cases were evaluated by all participants, who classified each case by stage,\ngrade and extent. The evaluations were compared with the gold standard provided by a panel of expert\nperiodontists. Statistical analysis, including Fleiss\u2019 kappa and chi-square tests, was performed to assess\nagreement and diagnostic accuracy. Results: Significant differences were observed in stage classification,\nwith students and recent graduates more likely to underestimate the severity of the disease, while experienced\ndentists tended to overestimate it. No significant differences were found in grade and extent classifications.\nDiagnostic accuracy was comparable across all groups, but students showed slightly higher agreement with\nthe gold standard compared to other groups. Conclusions: The 2017 AAP-EFP classification system can\nbe applied by both general dentists and dental students, but further clinical practice is needed to improve\ndiagnostic accuracy. Misclassification tendencies, such as over- or underestimation of disease severity,\nhighlight the need for additional training and familiarity with the system.<\/jats:p>","DOI":"10.54589\/aol.38\/2\/154","type":"journal-article","created":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T21:22:17Z","timestamp":1761859337000},"page":"154-161","source":"Crossref","is-referenced-by-count":2,"title":["Level of agreement among dental students and general dentists on the diagnosis of periodontitis using the new classification of periodontal diseases"],"prefix":"10.54589","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-3496-4784","authenticated-orcid":false,"given":"Fabio","family":"Herrero","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2728-4017","authenticated-orcid":false,"given":"Mar\u00eda","family":"Terenzani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9805-605X","authenticated-orcid":false,"given":"Luciano","family":"Marconi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7171-1533","authenticated-orcid":false,"given":"Ayel\u00e9n","family":"Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9061-3833","authenticated-orcid":false,"given":"Carlos D","family":"De la Vega Elena","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"31696","published-online":{"date-parts":[[2025,8,30]]},"container-title":["Acta Odontol\u00f3gica Latinoamericana"],"original-title":[],"deposited":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T21:40:00Z","timestamp":1761860400000},"score":1,"resource":{"primary":{"URL":"https:\/\/actaodontologicalat.com\/wp-content\/uploads\/2025\/10\/aol_2025_38_2_154.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,30]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2025,8,30]]}},"URL":"https:\/\/doi.org\/10.54589\/aol.38\/2\/154","relation":{},"ISSN":["1852-4834"],"issn-type":[{"value":"1852-4834","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,30]]}}}
