Management of intrusive luxation in the permanent dentition is controversial. The purpose of this study was to evaluate pulp survival and periodontal healing in intrusive luxated permanent teeth in relation to treatment alternatives, degree of intrusion and root development.<\/jats:p><jats:p><jats:bold>Material and Method:\u2002<\/jats:bold>The material consisted of 60 intruded permanent teeth in 48 patients (32 boys and 16 girls) aged 6\u201316\u2003years (mean 9.4, median 9.0). The observation time was 6\u2013130\u2003months (mean 47.8, median 40.0). The analysed treatments were spontaneous re\u2010eruption (17 teeth), orthodontic extrusion (12 teeth) and surgical reposition (31 teeth). The degree of intrusion was registered as mild (0\u20133\u2003mm), moderate (4\u20136\u2003mm) and severe (\u22657\u2003mm). Root development was categorized with respect to root formation and development of the apex into four stages; one\u2010quarter to three\u2010quarters root formation, full root formation with open apex, full root formation with half\u2010closed apex and full root formation with apex closed. Ankylosis\u2010related resorption with pulp necrosis was diagnosed in 20 teeth, ingrowth of bone apically in two teeth, pulp necrosis without ankylosis\u2010related resorption in 23 teeth and pulp revitalization occurred in 15 teeth.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold>Significant correlations to the treatment outcome were root development (<jats:italic>P<\/jats:italic>\u2003=\u20030.03) and degree of intrusion (<jats:italic>P<\/jats:italic>\u2003=\u20030.03).<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold>No firm conclusion could be drawn for the difference in outcome between orthodontic extrusion and surgical reposition. To conclude, evaluation of the prognosis for intruded teeth should be based on the stage of root development and degree of intrusion. In teeth with immature root development, no active treatment appears to result in fewer healing complications.<\/jats:p>","DOI":"10.1111\/j.1600-9657.2011.01088.x","type":"journal-article","created":{"date-parts":[[2011,11,23]],"date-time":"2011-11-23T12:32:30Z","timestamp":1322051550000},"page":"416-422","source":"Crossref","is-referenced-by-count":80,"title":["Intrusive luxation of 60 permanent incisors: a retrospective study of treatment and outcome"],"prefix":"10.1111","volume":"28","author":[{"given":"Georgios","family":"Tsilingaridis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbro","family":"Malmgren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens O.","family":"Andreasen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olle","family":"Malmgren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,11,23]]},"reference":[{"key":"e_1_2_7_2_2","volume-title":"Intrusive luxation","author":"Andreasen JO","year":"2007"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00421.x"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1997.tb00055.x"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1985.tb00583.x"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00422.x"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2003.06.019"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00423.x"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2000.016001034.x"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2003.00207.x"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF03262663"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(84)90122-2"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2008.00686.x"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(72)80042-5"},{"key":"e_1_2_7_15_2","first-page":"431","article-title":"A study of traumatized permanent teeth in children 7\u201315\u2003years.
