The degree of intrusion was classified as mild (1\u2013&lt;3 mm), moderate (3\u20137 mm), and severe (&gt;7 mm). Root development was categorized with respect to root formation and development of the apex into three groups of increasing tooth maturity: very immature, immature, and mature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Awaiting re\u2010eruption was the treatment of choice in 107 teeth (47%), orthodontic repositioning in 28 (12%) and surgical repositioning in 95 (41%) teeth. Pulp necrosis was diagnosed in 173 teeth (75%), infection\u2010related root resorption in 57 (25%) and replacement resorption in 50 teeth (22%). Very immature teeth, teeth diagnosed with mild intrusion, and teeth awaiting re\u2010eruption had significantly (<jats:italic>P<\/jats:italic> &lt; 0.05) fewer complications. In a stepwise discriminant function analysis, choice of treatment, root development, and degree of intrusion were significantly (<jats:italic>P<\/jats:italic> &lt; 0.05) associated with the development of replacement resorption. Root development and degree of intrusion were significantly (<jats:italic>P<\/jats:italic> &lt; 0.05) associated with the development of pulp necrosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study indicates that root development and degree of intrusion may be important for the development of pulp necrosis as well as replacement resorption, whereas choice of treatment only seems to influence the development of replacement resorption in intruded permanent teeth. Awaiting re\u2010eruption resulted in the lowest risk for developing replacement resorption.<\/jats:p><\/jats:sec>","DOI":"10.1111\/edt.12266","type":"journal-article","created":{"date-parts":[[2016,3,5]],"date-time":"2016-03-05T16:16:01Z","timestamp":1457194561000},"page":"353-360","source":"Crossref","is-referenced-by-count":35,"title":["Scandinavian multicenter study on the treatment of 168 patients with 230 intruded permanent teeth \u2013 a retrospective cohort study"],"prefix":"10.1111","volume":"32","author":[{"given":"Georgios","family":"Tsilingaridis","sequence":"first","affiliation":[{"name":"Department of Dental Medicine Division of Pediatric Dentistry Karolinska Institutet Stockholm Sweden"},{"name":"Department of Pediatric Dentistry Eastmaninstitutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbro","family":"Malmgren","sequence":"additional","affiliation":[{"name":"Department of Dental Medicine Division of Pediatric Dentistry Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens O.","family":"Andreasen","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery Resource Centre for Rare Oral Diseases University Hospital Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tove I.","family":"Wigen","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Behavioral Science Institute of Clinical Dentistry University of Oslo Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne\u2010Lise","family":"Maseng Aas","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Behavioral Science Institute of Clinical Dentistry University of Oslo Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olle","family":"Malmgren","sequence":"additional","affiliation":[{"name":"Orthodontic Clinic Huddinge Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,3,4]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00421.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2011.01103.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2011.01088.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2008.00686.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00423.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00422.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1985.tb00583.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12104"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1989.tb00348.x"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1995.tb00462.x"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1986.tb00133.x"},{"key":"e_1_2_6_13_1","first-page":"166","article-title":"Healing and sensitivity to pain in young replanted human teeth.
