Abstract：Objective Pulp revascularization is a therapy of regenerative endodontic procedures.However,the lack of suitable teaching and training models has hindered the widespread promotion and adoption of pulp revascularization.This study aims to develop a novel model and evaluate its effectiveness in the preclinical training of pulp revascularization.Methods The external and root canal anatomical data of the mandibular first premolars intended for pulp revascularization were obtained through 3D scanning technology and CBCT.The pulp revascularization model was designed and constructed for pulp revascularization teaching and preclinical training.Forty full-time fifth-year undergraduate dental students from West China School of Stomatology,Sichuan University participated in the preclinical course and randomly divided into control group and experimental group.Traditional teaching method(control group)or endodontic revascularization model assisted teaching method(experimental group)were adopted,respectively.The teaching effectiveness of the pulp revascularization model was investigated through practical examinations and student feedback questionnaires.Results The pulp revascularization model designed and constructed in this study successfully reproduced the root canal and periapical anatomical features of young permanent teeth,allowing for the implementation of clinical procedures of pulp revascularization.The operational evaluation demonstrated that the introduction of pulp revascularization models significantly improved performance across all steps of pulp revascularization.The average score of experimental group(7.69±0.51)was notably higher than that of the control group(4.91±0.66)(P<0.001).Survey responses indicated that more than 90%of students believed that the application of the pulp revascularization model had a positive impact on their mastery of theoretical knowledge,enhancement of operational skills.Conclusion The integration of 3D-printed pulp revascularization models into the preclinical training of pulp revascularization has achieved good teaching effect,and is worth further extension.
