Radiographs of individuals aged between 5 and 25\u00a0years were re-used to establish a reference data set (RDS). A scheme comprising 8 tooth development stages (TDS) was used to assess all the teeth on the left side of the maxilla and mandible. The accuracy of dental age estimation (DAE) was tested with a separate sample of radiographs \u2013 the validation sample (VS) comprised 50 females and 50 males of known chronological age (CA). Dental panoramic tomographs (DPT) of 1,597\u00a0Qataris were assessed.

There is a significant difference in dental age of 4.8\u00a0months in the female group when compared to the CA. The difference in the male group is 4.5\u00a0months. This shows similar differences to assessments of other ancestral or ethnic groups.<\/jats:p>","DOI":"10.1007\/s12024-023-00587-5","type":"journal-article","created":{"date-parts":[[2023,4,5]],"date-time":"2023-04-05T19:16:24Z","timestamp":1680722184000},"page":"59-72","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Dental age estimation: development and testing of a reference data set for Qatari children, adolescents, and young adults aged between 5 and 25\u00a0years"],"prefix":"10.1007","volume":"20","author":[{"given":"Noof","family":"Al-Obaidli","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Najat","family":"Al-Hashimi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria S.","family":"Lucas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8934-7200","authenticated-orcid":false,"given":"Graham","family":"Roberts","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,4,5]]},"reference":[{"key":"587_CR1","unstructured":"United Nations Convention on the Rights of the Child.\u00a01989. www.unicef.org\/child-rights-convention\/convention-text-children\u2019s-version"},{"key":"587_CR2","first-page":"221","volume":"45","author":"A Demirjian","year":"1973","unstructured":"Demirjian A, Goldstein H, Tanner JM.
