Traumatic dental injuries can range from simple enamel fractures to permanent tooth loss. This case report presents an eight-year-old patient with an uncomplicated crown fracture of tooth 21, and 30 days after trauma, it was diagnosed as necrotic pulp. The first treatment choice was a regenerative endodontic procedure (REP), however, the failure led to apexification with Mineral Trioxide Aggregate (MTA). The chosen rehabilitation was a composite veneer. Concerning the available literature and fracture enamel dentin, the treatment approach proposed for the case provided good functional and esthetic outcomes.<\/jats:p>","DOI":"10.3390\/dj8030094","type":"journal-article","created":{"date-parts":[[2020,9,1]],"date-time":"2020-09-01T08:53:43Z","timestamp":1598950423000},"page":"94","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Management of an Unsuccessful Regenerative Endodontic Procedure after Tooth Fracture: A Case Report"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4412-7102","authenticated-orcid":false,"given":"Lu\u00edsa","family":"Bandeira Lopes","sequence":"first","affiliation":[{"name":"Pediatric Department, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz, Egas Moniz Cooperativa de Ensino Superior, 2521-511 Caparica, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Paredes","sequence":"additional","affiliation":[{"name":"Pediatric Department, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz, Egas Moniz Cooperativa de Ensino Superior, 2521-511 Caparica, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreia","family":"Pimenta","sequence":"additional","affiliation":[{"name":"Clinical Research Unit (CRU), Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz (CiiEM), Instituto Universit\u00e1rio Egas Moniz (IUEM), 2521-511 Caparica, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1480-8997","authenticated-orcid":false,"given":"In\u00eas","family":"Carpinteiro","sequence":"additional","affiliation":[{"name":"Dentistry Department, Centro de Investiga\u00e7\u00e3o Interdisciplinar Egas Moniz, Egas Moniz Cooperativa de Ensino Superior, 2521-511 Caparica, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/S0109-5641(01)00047-1","article-title":"Bond durability of the resin-bonded and silane treated ceramic surface","volume":"18","author":"Hooshmand","year":"2002","journal-title":"Dent.
