Abstract: Introduction: There are numerous challenges in treating immature permanent teeth with a diagnosis of pulp necrosis. Three general treatment options are calcium hydroxide apexification, mineral trioxide aggregate (MTA) apexification, and revascularization. The objective of this retrospective study was to evaluate radiographic and clinical outcomes of immature teeth treated with 1 of these 3 methods. Methods: Clinical outcome data and radiographs were collected from 61 cases (ie, 22 calcium hydroxide apexification cases, 19 MTA apexification cases, and 20 revascularization cases). Both tooth survival and clinical success rates were analyzed. In addition, the preoperative and recall radiographs were analyzed to calculate the percentage increase in root width and length. Results: The percentage change of root width was significantly greater in the revascularization group (28.2%) compared with the MTA apexification (0.0%) and calcium hydroxide apexification groups (1.5%). In addition, the percentage increase of root length was significantly greater in the revascularization group (14.9%) compared with the MTA (6.1%) and calcium hydroxide apexification groups (0.4%). Moreover, the survival rate of the revascularization-treated teeth (100%) and MTA apexification-treated teeth (95%) were greater than the survival rates observed in teeth treated with calcium hydroxide (77.2%). Conclusions: In this study, revascularization was associated with significantly greater increases in root length and thickness in comparison with calcium hydroxide apexification and MTA apexification as well as excellent overall survival rates.
