Clinical and radiographic data was available for 35 patients (18 males, 17 females) representing 55 incisors. Mean age at the time of injury was 10.6\u2003years (range: 7.1\u201317.8\u2003years). Mean time elapsed to follow up was 1320\u2003days (range: 423\u20132887\u2003days). Survival analysis was used to identify variables significantly related to the prognosis of these teeth. The loss of an incisor following extrusion was uncommon as only one tooth (1\/55) required extraction. There was no statistically significant difference in survival between severely extruded teeth and avulsions that had been stored in physiological media (<jats:italic>P<\/jats:italic>\u2003&gt;\u20030.10). Pulp necrosis (PN) was the most common complication following injury (43%) and it most often occurred during the first year. Although not statistically significant, a trend towards increased PN was found with more severely extruded teeth (<jats:italic>P<\/jats:italic>\u2003=\u20030.20, relative risk\u2003=\u20032.08). Pulp canal obliteration (PCO) was the second most common outcome (35%). The degree of extrusion was proven to be significantly associated with the development of PCO (<jats:italic>P<\/jats:italic>\u2003=\u20030.03, relative risk\u2003=\u20030.33). Root resorption was an uncommon outcome (3\/55). This study represents the first outcome data on extrusions to permanent maxillary incisors in an exclusively pediatric population.<\/jats:p>","DOI":"10.1034\/j.1600-9657.2003.00208.x","type":"journal-article","created":{"date-parts":[[2003,9,9]],"date-time":"2003-09-09T08:34:20Z","timestamp":1063096460000},"page":"274-279","source":"Crossref","is-referenced-by-count":54,"title":["Clinical outcomes for permanent incisor luxations in a pediatric population.
