Objective:To evaluate the clinical effect of pulp revascularization in the treatment of immature permanent molars with complex root canal system, and to provide clinical basis for the diagnosis and treatment of pulp revascularization in young permanent molars.Methods:A total of nine patients with apical periodontitis of immature permanent molars, aged 7 to 13 years old, who were treated at the Department of Stomatology, Qingdao Municipal Hospital between January 2020 and June 2020, were included in this study. The sample consisted of three male patients and six females. They were all treated with pulp revascularization and followed up for 12 ~ 36 months. The healing of periapical lesions and root development were observed and evaluated.Results:During the follow-up observation period, seven cases were successful, while one case got improved, and one case failed, leading to the effective rate of 88.9%. Imaging examinations showed that in effective cases, the periapical radiolucency disappeared, while the root length increased, and the apical foramen closed. In addition, the root canal wall also thickened to varying degrees.Conclusions:Pulp revascularization in the treatment of chronic apical periodontitis of immature permanent molars was a highly feasible clinical operation, which can promote root elongation, apical foramen closure and root canal wall thickening.
