Posttraumatic external inflammatory root resorption (EIRR) is also a high\u2010risk complication often observed in children. Regenerative endodontic procedure (REP) has been considered a successful treatment to arrest EIRR, especially in posttraumatic cases. This case report presents clinical outcomes of REP in two teeth of an 8\u2010year\u2010old systemically healthy patient with a history of severe dentoalveolar traumatic injury, one with a history of avulsion, and the other with an EIRR. The treatment consisted of REP on both teeth #8 and #9. The results showed some evidence of maturation in the apical third of tooth #9 and resolution of signs and symptoms on tooth #8.<\/jats:p>","DOI":"10.1155\/2021\/4737104","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T19:35:26Z","timestamp":1633894526000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Regenerative Endodontic Treatment of Maxillary Incisors with a History of Severe Traumatic Injury"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7711-0310","authenticated-orcid":false,"given":"Nazanin","family":"Chitsaz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8967-4022","authenticated-orcid":false,"given":"Mehrfam","family":"Khoshkhounejad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8895-3524","authenticated-orcid":false,"given":"Hadi","family":"Assadian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8922-9802","authenticated-orcid":false,"given":"Behnam","family":"Bolhari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3638-7273","authenticated-orcid":false,"given":"Mohammadreza","family":"Sharifian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0099-1380","authenticated-orcid":false,"given":"Zahra","family":"Mohammadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,10,8]]},"reference":[{"key":"e_1_2_6_1_2","volume-title":"Textbook and Color Atlas of Traumatic Injuries to the Teeth","author":"Andreasen J.
