The studies evaluated patients in transition from deciduous to mixed, mixed to permanent, and deciduous to mixed dentition. Two studies had a low risk of bias, three had a moderate risk, and two had a high risk of bias. The results showed posterior crossbite self-correction frequencies ranging from 12.2 to 77.1% during the transition from primary to mixed dentition, approximately 16% from mixed to permanent dentition, and a range from 20 to 82.8% from deciduous to permanent dentition. The level of certainty of the evidence generated ranged from very low to moderate.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Limitations<\/jats:title>\n                  <jats:p>The observational design of the studies, without adequate control for confounding factors, and non-classification of the samples considering the types or the severity of the posterior crossbite.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The self-correction of posterior crossbite in childhood is possible. However, the results of this research do not allow to affirm how often the self-correction of posterior crossbite can occur. New studies that assess factors associated with the occurrence of self-correction of this malocclusion, including oral habits, may increase the certainty of the evidence.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Registration<\/jats:title>\n                  <jats:p>PROSPERO CRD42022311935<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ejo\/cjad034","type":"journal-article","created":{"date-parts":[[2023,7,16]],"date-time":"2023-07-16T03:06:12Z","timestamp":1689476772000},"page":"739-746","source":"Crossref","is-referenced-by-count":5,"title":["Self-correction of posterior crossbite in childhood: a systematic review of long-term follow-up studies"],"prefix":"10.1093","volume":"45","author":[{"given":"Bianka Costa do","family":"Nascimento","sequence":"first","affiliation":[{"name":"School of Dentistry, Federal University of Par\u00e1 , Bel\u00e9m , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4572-1074","authenticated-orcid":false,"given":"Cibelle Cristina Oliveira dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Federal University of Par\u00e1 , Bel\u00e9m , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milena Cristina Costa dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Federal University of Par\u00e1 , Bel\u00e9m , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1335-1040","authenticated-orcid":false,"given":"David","family":"Normando","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Federal University of Par\u00e1 , Bel\u00e9m , Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,7,15]]},"reference":[{"key":"2023113008163649800_CIT0001","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/0002-9416(70)90201-0","article-title":"Tongue-thrust in preschool children.
