The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of reference service at the Universidade Federal de Pelotas, Pelotas, Brazil. In most cases, the maxillary central incisors (85.7%) were involved. In the crown, 57.1% of the cases had a simple line of fracture, and 42.9% had multiple lines. Simple lines predominated in the root (89.3%). In cases with simple fracture lines in the crown, 37.6% underwent a total extraction, 31.2% required a partial extraction and 31.2% underwent pulpectomy. In most teeth with multiple lines of fractures in the crown, total extraction was performed (91.7%) All cases were followed-up until the eruption of the permanent successor tooth, and all patients had favorable outcomes.<\/jats:p>","DOI":"10.1590\/0103-6440201600315","type":"journal-article","created":{"date-parts":[[2016,4,2]],"date-time":"2016-04-02T21:50:09Z","timestamp":1459633809000},"page":"234-238","source":"Crossref","is-referenced-by-count":5,"title":["Crown-Root Fractures in Primary Teeth: A Case Series Study of 28 Cases"],"prefix":"10.1590","volume":"27","author":[{"given":"Vanessa Polina Pereira da","family":"Costa","sequence":"first","affiliation":[{"name":"Universidade Federal de Pelotas,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luisa Jardim Correa","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pelotas,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise Paiva","family":"Rosa\u00b9","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pelotas,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariana Gonzalez","family":"Cademartori","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pelotas,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dione Dias Torriani(in","family":"memoriam)","sequence":"additional","affiliation":[{"name":"Universidade Federal de Pelotas,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","article-title":"Textbook and Color Atlas of Traumatic Injuries to the Teeth","author":"Andreasen JO","year":"2007","journal-title":"Oxford.
