All cases were treated between June 1988 and June 1998 in a teaching hospital clinic. Clinical and radiographic data were collected for 26 patients (19 males, 7 females) that represented 31 permanent maxillary incisors. Mean age at the time of injury was 9.3\u2003years (range\u2003=\u20035.5\u201317.8\u2003years). Mean time elapsed to follow up was 1380\u2003days (range\u2003=\u200365\u20133394\u2003days). Survival analysis was used to identify variables significantly related to the survival and pulp necrosis (PN) for these incisors. Proportional hazards regression yielded significant prognostic models for tooth survival and the diagnosis of PN (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). Incisors intruded &gt;6\u2003mm had significantly decreased survival compared with incisors intruded &lt;3\u2003mm (5\u2010year survival, 0.45 and 1.0, respectively, (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05)). Complex crown fractures were significantly related to the development of PN (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). Logistic regression analysis showed that treatment method and severity of intrusion were related to the presence of replacement root resorption (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). This study represents the largest sample of intruded permanent incisors examined in an outcome study of children and adolescents exclusively.<\/jats:p>","DOI":"10.1034\/j.1600-9657.2003.00207.x","type":"journal-article","created":{"date-parts":[[2003,9,9]],"date-time":"2003-09-09T08:34:20Z","timestamp":1063096460000},"page":"266-273","source":"Crossref","is-referenced-by-count":91,"title":["Clinical outcomes for permanent incisor luxations in a pediatric population.
