The study included 89 patients with clefts treated at the Oulu University Hospital. The subjects were divided into three groups: cleft palate, cleft lip, and cleft lip and palate. Study casts were scanned, and the maxillary arch dimensions were examined using a 3D program (3Shape Orthoanalyzer, Copenhagen, Denmark). The statistical methods Student\u2019s t-test and one-way ANOVA were used to compare the means (SD) between the groups. Spearman\u2019s correlation coefficient was used to determine the correlation between cleft severity and maxillary dimensions. A significant difference was found between different initial cleft sizes in terms of distance between the second deciduous molar and the first incisor on the right side. The intermolar width showed a negative correlation with the initial cleft size. The dimensions were shorter for clefts affecting the palate and largest for clefts affecting only the lip. Larger clefts resulted in a shorter maxilla on the right side. Many dimensions became shorter when the initial cleft was larger. Clefts of the palate resulted in smaller maxillas.<\/jats:p>","DOI":"10.3390\/ijerph18147432","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T21:56:37Z","timestamp":1626126997000},"page":"7432","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Maxillary Arch Dimensions in 6-Year-Old Cleft Children in Northern Finland: A Cross-Sectional Study"],"prefix":"10.3390","volume":"18","author":[{"given":"Mirjami","family":"Corcoran","sequence":"first","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3160-8137","authenticated-orcid":false,"given":"Saujanya","family":"Karki","sequence":"additional","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leena","family":"Ylikontiola","sequence":"additional","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"},{"name":"Medical Research Centre Oulu, Oulu University Hospital and University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riitta","family":"Lithovius","sequence":"additional","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"},{"name":"Medical Research Centre Oulu, Oulu University Hospital and University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George K.","family":"S\u00e1ndor","sequence":"additional","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"},{"name":"Medical Research Centre Oulu, Oulu University Hospital and University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5272-6300","authenticated-orcid":false,"given":"Virpi","family":"Harila","sequence":"additional","affiliation":[{"name":"Research Unit of Oral Health Sciences, University of Oulu, 90220 Oulu, Finland"},{"name":"Medical Research Centre Oulu, Oulu University Hospital and University of Oulu, 90220 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"372","DOI":"10.3109\/00016357.2013.840737","article-title":"A descriptive epidemiology study of cleft lip and palate in Northern Finland","volume":"72","author":"Lithovius","year":"2014","journal-title":"Acta Odontol.
