Abstract: Objective: To evaluate the clinical effect of pulp revascularization for the immature permanent teeth with wide apical foramen. Methods: Eleven immature permanent teeth with wide apical foramens from 9 patients were selected. The pulp of teeth was exposed and the necrotic tissue was cleaned up using the oral surgery microscope. Triple antibiotic cataplasm were sealed in the root canals after irrigation with 2.5% sodium hypochlorite and 17% EDTA solution. Pulp revascularization was operated when the tooth had no clinical symptoms. The accesses of the cavities were filled with composite resins. Results: The clinical symptoms of 9 patients (11 teeth) disappeared after pulp revascularization, among which the periapical lesions of six teeth were healed and the apical foramens were narrowed with pulp vitality responses, the periapical lesions of four teeth were healed and the apical foramens were getting narrow without pulp vitality responses, and one tooth was failed. Conclusion: Pulp revascularization was an effective treatment for immature permanent teeth with wide apical foramen.
