Unmonitored apexification of wide open apex in nonvital, immature incisor: a case report.

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 erupting maxillary central incisor in 7-year-old female child with immature root (half root) formation and wide open apex. Although it was an induced procedure, but unmonitored. Patient did not return until 18 months after his first visit. Treatment then concluded with gutta percha obturation against firm "cap shaped" apical stop.
