Abstract:
Objective:To analyze the influencing factors related to the prognosis of delayed replantation of avulsed permanent teeth.Methods:A retrospective study was conducted on the clinical data of 35 patients with 38 affected teeth underwent delayed replantation of permanent teeth.According to the prognosis after 12 to 108 months of follow-up,the replantation results of the cases were divided into-success,survival and failure groups.Survival curves were plotted using Kaplan-Meier method,Log-Rank test was used for univariate analysis,and Cox proportional risk regression models were used for multivariate analysis to assess the effects of gender,age,degree of tooth development,mode of tooth preservation and mode of endodontic treatment on the survival rate of replanted teeth.Results:Of the 38 replanted teeth,3 were successful,28 remained and 10 failed.The 9-year cumulative survival rate of the replanted teeth was 34.7%.The results showed that there were no statistically significant differences in the survival rate of the replanted teeth in the groups with different sex,age,degree of tooth development and the mode of preservation of avulsed teeth(P>0.05).There were statistically significant differences in the cumulative survival rate of the replanted teeth among the groups with different endodontic treatment(P<0.01),which showed that the cumulative survival rate in the root canal filling group>continuous root canal sealing group>pulp preserva-tion treatment group.Conclusion:For the delayed replantation of avulsed premanent teeth,survival prognosis of the teeth treated with pulp preservation is poor,early pulp extraction and root canal filling are recommended.
