The majority were found in the 9\u201013\u2010year\u2010old age group (0.8% prevalence within the total population). In all, 244 canines were assessed for eligibility and 181 had adequate final radiographs for evaluation of RR. Among ectopic maxillary canines, 9.4% caused severe incisor RR to neighbouring teeth. Timely palpation for canine eruption significantly reduced the odds for upper incisor resorption by 80%. Multiple regression showed that when the permanent canine cannot be palpated and the deciduous has been extracted, delaying the first X\u2010rays was associated with a 38% odds ratio increase for RR for each year of delay after the age of 10\u2009years. No significant associations were found between incisor RR and intervention conducted or other dental anomalies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Palpation of erupting maxillary canines is crucial for timely diagnosis of ectopic eruption and initiation of treatment to avoid RR. If the canine cannot be palpated at 10\u2009years of age, radiographic examination is highly recommendable.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ocr.12703","type":"journal-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T08:23:46Z","timestamp":1691742226000},"page":"165-173","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Apical incisor root resorption due to ectopic maxillary canine eruption: Association with time of diagnosis and type of intervention in a retrospective population\u2010based cohort study"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5514-2960","authenticated-orcid":false,"given":"Susanna","family":"Botticelli","sequence":"first","affiliation":[{"name":"Section of Orthodontics Aarhus University  Aarhus Denmark"},{"name":"Cleft Lip and Palate Department Istitut for Kommunikation og Handikap  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tina","family":"Byriel","sequence":"additional","affiliation":[{"name":"Section of Orthodontics Aarhus University  Aarhus Denmark"},{"name":"Orthodontic Municipality Clinic FKO Syddjurs Kommune  R\u00f8nde Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0903-6718","authenticated-orcid":false,"given":"Peter","family":"Stoustrup","sequence":"additional","affiliation":[{"name":"Section of Orthodontics Aarhus University  Aarhus Denmark"},{"name":"Orthodontic Municipality Clinic Aars  Aars Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7604-3259","authenticated-orcid":false,"given":"Paolo Maria","family":"Cattaneo","sequence":"additional","affiliation":[{"name":"Melbourne Dental School, Faculty of Medicine, Dentistry and Health Sciences University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9133-4644","authenticated-orcid":false,"given":"Annelise","family":"K\u00fcseler","sequence":"additional","affiliation":[{"name":"Section of Orthodontics Aarhus University  Aarhus Denmark"},{"name":"Cleft Lip and Palate Department Istitut for Kommunikation og Handikap  Aarhus Denmark"},{"name":"Department of Oral and Maxillofacial Surgery Aarhus University Hospital  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-009-0262-8"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2014.09.012"},{"issue":"2","key":"e_1_2_9_4_1","first-page":"95","article-title":"Does the canine dental follicle cause resorption of permanent incisor roots?
