title: Traumatically intruded permanent incisors: a study of treatment and outcome.
abstract: Twenty-nine traumatically intruded permanent maxillary incisors from 20 patients were examined, treated and monitored for 2 years. There was a higher proportion of males than females. The teeth intruded furthest were more frequently extracted. Those which were surgically repositioned were more frequently retained and were associated with marginal bone loss significantly less frequently than those which were passively observed, while external root resorption occurred in similar proportions in both groups. A significantly higher proportion of those teeth that were delayed in presentation were subsequently extracted, and a similar trend was found for those with immature roots at the time of the initial examination.
