Root fractures are rare and have a reported incidence of 2% in the primary dentition. Hence, there is limited evidence on this topic. This study aims to evaluate the risk of healing complications in primary teeth with root fracture and to identify possible sequelae in the permanent dentition following root fracture in the primary dentition.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>A retrospective analysis of a cohort of 53 patients with 74 root fractured primary teeth. The standard follow\u2010up program included clinical and radiographic examination after 4\u2009weeks, 8\u2009weeks, 6\u2009months, and 1\u2009year after the trauma and when the patient was 6\u2009years of age. The following complications were registered: pulp necrosis (PN), pulp canal obliteration (PCO), ankylosis with replacement root resorption (ARR), infection\u2010related root resorption (IRR), premature tooth loss (PTL), and repair\u2010related resorption (RRR). Statistics: The Kaplan\u2013Meier and Aalen\u2010Johansen estimators were employed. The level of significance was 5%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 74 teeth were included. 42 teeth were extracted at the initial examination. Risks estimated after 3\u2009years: PTL 45.9% [95% CI: 28.8\u201363.0], PCO 12.9% [95% CI: 2.3\u201323.4], PN 14.9% [95% CI: 3.9\u201325.9], RRR 2.6% [95% CI: 0.0\u20137.5]. No teeth showed ARR or IRR. All complications were diagnosed within the first year. Most common sequelae in the permanent dentition was demarcated opacities, with an estimated risk of 20% [95% CI: 8.2\u201341.3].<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There is a low risk of healing complications following a root fracture in the primary dentition. Root fractures often result in early extraction of the coronal fragment. The remaining apical fragment will undergo a physiological resorption. Aside from opacities, there is a low risk of sequelae in the permanent dentition.<\/jats:p><\/jats:sec>","DOI":"10.1111\/edt.12853","type":"journal-article","created":{"date-parts":[[2023,6,7]],"date-time":"2023-06-07T03:06:54Z","timestamp":1686107214000},"page":"455-461","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The risk of healing complications in primary teeth with root fractures: A retrospective cohort study"],"prefix":"10.1111","volume":"39","author":[{"given":"Mir","family":"Kevci","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery and Oral Medicine Malm\u00f6 University  Malm\u00f6 Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Alexander","family":"Gerds","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0859-7262","authenticated-orcid":false,"given":"Eva","family":"Lauridsen","sequence":"additional","affiliation":[{"name":"Resource Centre for Rare Oral Diseases Department of Oral and Maxillo\u2010Facial Surgery Copenhagen University Hospital  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1035-2539","authenticated-orcid":false,"given":"Lars","family":"Andersson","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery and Oral Medicine Malm\u00f6 University  Malm\u00f6 Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,5]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12389"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(72)80042-5"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2005.00362.x"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2008.00696.x"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12482"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2001.170501.x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0011-8532(22)00624-3"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.25241\/stomaeduj.2019.6(4).bookreview.3"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12576"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016357.2017.1414956"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2019.05.006"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12149"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.3390\/dj10050074"},{"key":"e_1_2_8_15_1","first-page":"865","article-title":"Root fractures in the primary dentition","volume":"77","author":"Dynesen H","year":"1973","journal-title":"Tandlaegebladet"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1998.tb00806.x"},{"key":"e_1_2_8_17_1","first-page":"399","article-title":"Pulp canal obliteration following trauma to primary incisors: a 9\u2010year clinical study","volume":"33","author":"Santos BZ","year":"2011","journal-title":"Pediatr Dent"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12342"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12341"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12340"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0528.1974.tb01669.x"},{"key":"e_1_2_8_22_1","first-page":"103","article-title":"The formation and the alveolar and clinical eruption of the permanent teeth.
