Sequelae to trauma to immature maxillary central incisors: a case report.

This case report highlights (i) a rare example of spontaneous apexification despite pulp necrosis and periradicular pathosis, and (ii) pulpal necrosis and periapical pathosis following secondary trauma. The initial trauma occurred in a seven-year-old female who received secondary trauma 4 years later. The diagnosis and management of both maxillary central incisors as well as follow-up assessments for both immature and mature teeth subjected to trauma is discussed.
