The present study reported clinical management of external root resorption of an avulsed and reimplanted maxillary central incisor. Case report: A 9-year-old boy reported an uncomplicated crown fracture and avulsion of tooth 11 and complicated crown fracture of tooth 21 due to trauma. Reimplantation of element 11 was obtained within 30 min post-trauma and 3 days after both elements were diagnosed with necrotic pulp. In addition, tooth 11 showed early external root resorption. Both elements underwent endodontic treatment and root closure with apical plug using calcium-silicate-based cement. At 6-month follow-up root resorption appeared to be arrested. Twenty-four months after trauma the clinical results were stable, although signs and symptoms of ankylosis were observed. Conclusions: An immediate endodontic approach and use of calcium-silicate-based cement seemed to contrast the progression of root resorption of an avulsed and reimplanted central incisor after 24 months of follow-up.<\/jats:p>","DOI":"10.3390\/dj9060072","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T10:27:07Z","timestamp":1623839227000},"page":"72","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["External Root Resorption Management of an Avulsed and Reimplanted Central Incisor: A Case Report"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6251-4072","authenticated-orcid":false,"given":"Gianni","family":"Di Giorgio","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Science, \u201cSapienza\u201d University of Rome, Via Caserta, 6, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Salucci","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Science, \u201cSapienza\u201d University of Rome, Via Caserta, 6, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gian Luca","family":"Sfasciotti","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Science, \u201cSapienza\u201d University of Rome, Via Caserta, 6, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flavia","family":"Iaculli","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Science, \u201cSapienza\u201d University of Rome, Via Caserta, 6, 00161 Rome, Italy"},{"name":"Department of Neuroscience and Reproductive and Odontostomatological Sciences, University of Naples \u201cFederico II\u201d, Via Pansini, 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Boss\u00f9","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Science, \u201cSapienza\u201d University of Rome, Via Caserta, 6, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"331","DOI":"10.1111\/edt.12573","article-title":"International association of dental traumatology guidelines for the management of traumatic dental injuries: 2.
