Immature permanent teeth may develop pulpal pathosis due to caries or trauma and preserving these young teeth is quintessential. The general consensus for clinical treatment of immature teeth with non-vital pulps is Apexification. However, this treatment modality does not result in further root development and increase incidence of root fractures in teeth after apexification. Regenerative Endodontics has been defined as biologically based procedures designed to replace damaged structures such as dentin, root structures, and cells of the pulp-dentin complex. The advantages of pulp revascularization lie in the possibility of further root development and reinforcement of dentinal walls by deposition of hard tissue, thus strengthening the root against fracture. This retrospective study evaluated treated cases by regenerative endodontic procedures performed by Endodontists/endodontic residents in the United States/Canada with a minimum of 1-year recall. The participating Endodontists evaluated the regeneration success parameters as defined by the AAE and filled out a Data Collection Form for each patient. 27 of the 28 submitted cases showed absence of clinical symptoms and apical resolution of pathology at the time of one year follow up; 19 cases showed increase in the root width; 15 cases showed increase in the root length; However none of the cases showed any positive response to pulp vitality tests. The results obtained are promising and prove that pulp regeneration/revascularization is indeed a viable treatment option. Further investigation should be considered with a larger sample size for a valid statistical analysis.
