title: Apexification of wide-open apices in nonvital, immature permanent incisors: a case report.
abstract: Apexification is the accepted procedure to form an apical stop in nonvital teeth with incomplete root formation. A case is presented in which apexification with calcium hydroxide was performed on two permanent central incisors with immature roots and wide-open apices; treatment concluded with gutta-percha root canal restoration. Spontaneous apical seal had probably been initiated before the calcium hydroxide was inserted, but it was weak and nonhomogenous.
