Abstract: This research aimed to evaluate the outcomes of autotransplantation in both children and adolescents, with a focus on root growth, and determine the clinical and radiographic factors associated with the success rate. In this study, 73 teeth, autogenously transplanted in 63 patients, were examined over an observation period of 3.2 years on average. The mean age at the time of autotransplantation was 11.9 years. Based on the radiographic criteria, the success rate was 73.97% and the survival rate was 100%. Based on the radiographic criteria, the success rate was 73.97%, and the survival rate was 100%. A significant increase in root length was observed in the transplanted teeth with an open apex. An association was found between the success rate and use of bone graft and surgeon experience. In conclusion, greater clinical experience in autotransplantation (> 36 cases) and prohibiting the use of bone grafts may improve the prognosis of the transplanted teeth in children and adolescents.
