Some unusual cases of apexification subsequent to trauma.
Three cases are reported in which apexification occurred without the benefit of endodontic treatment. These reports illustrate that immature teeth which are avulsed and replanted, dislocated and repositioned, or traumatized with pulp necrosis supervening, may progress to form complete apices without intracanal therapy. The value of using calcium hydroxide is not in question, but may not be as essential an aid to apical closure as was previously thought. In one case, the appearance of isolated apixes forming, deep in the bone after loss of very immature lateral incisors poses the question of whether this event does not occur more frequently after extraction of newly erupted or young impacted teeth.
