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.

Complications and survival rates of teeth after dental trauma over a 5-year period

“…4 The Kaplan-Meier estimator shows the pulp survival for luxations as well as complicated and uncomplicated fractures in the permanent dentition 57.7 to 80 % for avulsions [19,[30][31][32][33][34][35][36]. The percentage of resorption in permanent dentition after severe luxation injuries, such as avulsions and intrusion, in this study is low (2/ 16; 12.5 %).…”

Orthodontic repositioning of traumatically intruded maxillary incisors minimizes negative sequelae

“…The observation and surgical repositioning rates that they cite were from a controlled, prospective study. 1 This type of study reduces bias, which is a benefit in assessing the true effect of an intervention. However, the decreased bias associated with higher levels of evidence often results in a finding of less benefit from an intervention compared to studies that are of lower quality.…”

Eruption of teeth in the nose following trauma to the primary and permanent dentitions

“…Conservative treatment is generally advocated for both primary and secondary incisor teeth, which usually erupt within one to six months of intrusion. 9 Definitive management of the intruded permanent incisor tooth is not universally agreed 10 but permanent incisor teeth with incomplete root formation often re-erupt spontaneously. 11 The opinion of an orthodontist may be appropriate at an early stage of management.…”
