Data were collected prospectively but examined retrospectively. Children were selected who had been initially screened in their deciduous dentition and on at least one consecutive year, presenting with a posterior crossbite in the deciduous or mixed dentition. Those with a posterior crossbite in the deciduous dentition were evaluated to see whether the crossbite persisted in the mixed dentition, and vice versa.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Of the 2571 children participating in the annual dental screenings, 1076 children were in the deciduous dentition at their first screening appointment, with 693 having attended at least two screening appointments. Of these 693 children, 70 had a posterior crossbite in the deciduous dentition (10.1%). The crossbite persisted in the mixed dentition in only 16 out of these 70 children. Twenty-six out of the 623 children who did not have a posterior crossbite in the deciduous dentition developed one in the mixed dentition.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Limitations<\/jats:title>\n                  <jats:p>The retrospective data collection, multiple examiners carrying out the dental screenings, and the absence of data on para-functions and oral habits were some of the limitations of the present study.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In the present sample, 1 in 10 children have a posterior crossbite in the deciduous dentition, which is however autocorrected in about three-quarters of cases. On the other hand, 4% of children developed a new crossbite in the mixed dentition. It may thus be reasonable in cases with posterior crossbite in the deciduous dentition to wait for the first permanent molars to erupt before initiating treatment.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ejo\/cjac061","type":"journal-article","created":{"date-parts":[[2022,9,19]],"date-time":"2022-09-19T09:57:53Z","timestamp":1663581473000},"page":"266-270","source":"Crossref","is-referenced-by-count":9,"title":["Spontaneous correction and new development of posterior crossbite from the deciduous to the mixed dentition"],"prefix":"10.1093","volume":"45","author":[{"given":"Meryam","family":"Khda","sequence":"first","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine, University of Geneva , Geneva , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stavros","family":"Kiliaridis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine, University of Geneva , Geneva , Switzerland"},{"name":"Department of Orthodontics and Dentofacial Orthopedics, Dental School\/Medical Faculty, University of Bern , Bern , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6741-6922","authenticated-orcid":false,"given":"Gregory S","family":"Antonarakis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine, University of Geneva , Geneva , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,10,7]]},"reference":[{"key":"2023053114084698000_CIT0001","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1051\/orthodfr\/2014008","article-title":"[How to push the limits in the transverse dimension?
