Abstract：Objective To analyze the effect of fenestration combined with orthodontic traction on the root growth child patients with maxillary central incisor embedded in dental cysts of replacement stage. Methods Retrospective analysis was performed on the data of 48 child patients with maxillary central incisor embedded in dental cysts of replacement stage admitted to Department of Stomatology, Ningde Municipal Hospital of Ningde Normal University from November 2016 to November 2021. According to the surgical methods, they were divided into control group (44 affected teeth, standard square wire bow technique correction) and observation group (46 affected teeth, fenestration combined with orthodontic traction). The root length and root canal wall thickness of two groups were compared before and after treatment; the level and thickness of labial-palatal alveolar bone were compared between two groups after treatment. Results After treatment, the root length and root canal wall thickness of two groups were greater than those before treatment, and observation group was greater than control group, and the differences were statistically significant (P＜0.05). There was no significant difference in the level and thickness of palatal alveolar bone between two groups (P＞0.05); the level and thickness of labial alveolar bone in observation group were less than those in control group, and the differences were statistically significant (P＜0.05). Conclusion Fenestration combined with orthodontic traction can promote the normal development of root and canal wall in patients with maxillary central incisor embedded in dental cysts of replacement stage.
