The clinical characteristics suggested the possibility of a reactive fibroma and we decided to intervene surgically by means of an excisional biopsy. Histology confirmed the presumptive diagnosis. Prompt referral and early surgical care spontaneously favoured both repositioning of the displaced primary tooth and closure of the diastema. This is an infrequent lesion in paediatric patients.<\/jats:p>","DOI":"10.1136\/bcr-2022-249369","type":"journal-article","created":{"date-parts":[[2022,3,16]],"date-time":"2022-03-16T12:10:35Z","timestamp":1647432635000},"page":"e249369","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Oral irritation fibroma associated with the pathological migration of a primary tooth"],"prefix":"10.1136","volume":"15","author":[{"given":"Anastasiya","family":"Lapitskaya","sequence":"first","affiliation":[{"name":"Department of Paediatric Dentistry, Hospital Sant Joan de D\u00e9u, University of Barcelona, Barcelona, Catalonia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pau","family":"Cahuana-Bartra","sequence":"additional","affiliation":[{"name":"Department of Paediatric Dentistry, Hospital Sant Joan de D\u00e9u, University of Barcelona, Barcelona, Catalonia, Spain"},{"name":"Department of Odontostomatology, Faculty of Medicine and Health Sciences, University of Barcelona, Barcelona, Catalonia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Llu\u00eds","family":"Brunet-Llobet","sequence":"additional","affiliation":[{"name":"Department of Paediatric Dentistry, Hospital Sant Joan de D\u00e9u, University of Barcelona, Barcelona, Catalonia, Spain"},{"name":"Hospital Dentistry, Clinical Orthodontics and Periodontal Medicine Research Group (HDCORPEMrg), Institut de Recerca Sant Joan de D\u00e9u (IRSJD), Barcelona, Catalonia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8211-1561","authenticated-orcid":false,"given":"Jaume","family":"Miranda-Rius","sequence":"additional","affiliation":[{"name":"Department of Odontostomatology, Faculty of Medicine and Health Sciences, University of Barcelona, Barcelona, Catalonia, Spain"},{"name":"Hospital Dentistry, Clinical Orthodontics and Periodontal Medicine Research Group (HDCORPEMrg), Institut de Recerca Sant Joan de D\u00e9u (IRSJD), Barcelona, Catalonia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,3,16]]},"reference":[{"key":"2025082708594622000_15.3.e249369.1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.coms.2015.07.005","article-title":"Pediatric benign soft tissue oral and maxillofacial pathology","volume":"28","author":"Glickman","year":"2016","journal-title":"Oral Maxillofac Surg Clin North Am"},{"key":"2025082708594622000_15.3.e249369.2","doi-asserted-by":"crossref","first-page":"76","DOI":"10.4103\/jomfp.JOMFP_350_19","article-title":"Relative frequency of oral focal reactive overgrowths: an institutional retrospective study","volume":"24","author":"Lakkam","year":"2020","journal-title":"J Oral Maxillofac Pathol"},{"key":"2025082708594622000_15.3.e249369.3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0714.2010.00895.x"},{"key":"2025082708594622000_15.3.e249369.4","first-page":"486","article-title":"Pediatric localized reactive gingival lesions: a retrospective study from Israel","volume":"32","author":"Buchner","year":"2010","journal-title":"Pediatr Dent"},{"key":"2025082708594622000_15.3.e249369.5","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(86)90010-1"},{"key":"2025082708594622000_15.3.e249369.6","unstructured":"Moret Y , Rivera H , Cartaya M .
