Abstract Objective The aim of this study was to evaluates histologically apical closure of autogenously transplanted immature permanent dog teeth treated with 3 different revascularization protocols Study design Sixty single-rooted maxillary incisor teeth from ten healthy Mongrel dogs aged 5 months were randomly divided into 3 experimental groups of 20 teeth each. Group I Autotransplantation without regenerative endodontic procedures. Group II: Autotransplantation with regenerative endodontic procedures after removal of their pulps coronally one week past transplantation. Group III Autotransplantation after removing pulp tissue from the apical side and treated with regenerative endodontic procedure one week past transplantation. The animals were sacrificed, histologic sections were prepared and three groups were evaluated for apical closure. Results Only 37.9% of teeth of all groups showed histological apical closure, with significant differences between the three groups (p = 0.008). Group I showed the maximal percentage (66.7%) and group II the minimum (20%). When the experimental groups were compared, there were significant differences between groups I and II (p = 0.004), and groups I and III (p = 0.024). While with group II and III; no statistical significant difference was found (p = 0.465). Conclusion These results suggest that autotransplantation procedures better done without removal of the original pulp tissue or further regenerative endodontic procedures.
