The aim of this study was to examine the probability of spontaneous re\u2010eruption of injured teeth, to investigate the incidence of pulp necrosis with infection of the root canal system and replacement root resorption and to analyse possible factors related to healing complications after injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Clinical data from 6\u2010 to 18\u2010year\u2010old patients who sustained intrusive luxation from 2007 to 2016 were reviewed. Teeth were treated by awaiting re\u2010eruption, orthodontic repositioning or surgical repositioning. The incidences of spontaneous re\u2010eruption, pulp necrosis with infection, replacement resorption and marginal bone loss were calculated, and factors related to these complications were analysed using Cox regression and Kaplan\u2010Meier analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Data from 79 teeth in 58 patients (mean age 9.19\u00a0\u00b1\u00a02.34\u00a0years) were examined over follow\u2010up periods from 7 to 87\u00a0months (median 18\u00a0months). Of the 50 teeth awaiting re\u2010eruption, the incidences of complete re\u2010eruption and partial re\u2010eruption were 40.0% and 34.0%, respectively. Teeth intruded &lt;3\u00a0mm had a higher complete re\u2010eruption rate (57.1%) than those with a 3\u20107\u00a0mm of intrusion (18.2%) (hazard ratio [HR]\u00a0=\u00a04.15). Of the 52 teeth observed for more than 12\u00a0months, pulp necrosis with infection, replacement resorption and marginal bone loss occurred in 57.4%, 15.4% and 61.5% of the teeth, respectively. Teeth with 3\u20107\u00a0mm (60.9%, HR\u00a0=\u00a02.97) or &gt;7\u00a0mm (100%, HR\u00a0=\u00a06.44) of intrusion and teeth with uncomplicated crown fracture (85.7%, HR\u00a0=\u00a05.19) were more likely to develop pulp necrosis with infection. Teeth that received orthodontic or surgical repositioning showed higher incidences of replacement resorption (23.1%, HR\u00a0=\u00a05.72; 25.0%, HR\u00a0=\u00a011.68, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Spontaneous re\u2010eruption of intruded teeth was significantly related to intrusion depth.
