Late term complications of intruded permanent incisors: 2 case reports

Abstract

This report describes 2 cases of intrusive luxation injuries of maxillary immature permanent central incisors. In both cases, intruded teeth were left for spontaneous re-eruption. During periodic follow-ups for up to 2 years the teeth did not show any sign, clinically or radiographically, of pulp necrosis with apical periodontitis. However, in the first case tenderness to percussion and periapical radiolucency developed after 2.5 years and endodontic treatment was started. In the second case, the patient returned after 2 years 9 months with complaint and periapical radiolucency was observed radiographically. Endodontic therapy was performed. These late-term complications highlight the need for regular long-term follow-up in cases of intrusive luxation in permanent teeth.
