Abstract：Objective To compare the clinical efficacy of Ceramage resin inlay and resin filling in the repair of pulp-less immature permanent molars with large-area defect.Methods A retrospective analysis was performed on 35 patients with 40 pulpless immature permanent molars with large-area defect treated from January 2016 to January 2017.The patients were divided into Ceramage resin inlay group(16 patients,18 teeth)and resin filling group(19 patients,22 teeth)according to re-pair methods.The Ceramage resin inlay group was repaired using Ceramage polymer ceramic inlay,while the resin filling group was repaired using direct resin filling.The restorations were evaluated according to the modified the United States Public Health Service(USPHS)standard at 1 and 6 years after the restoration,and the shedding of the restorations in the two groups was compared.Results At 1 year after repair,there was no significant difference in clinical effect between the two groups(P>0.05).At 6 years after restoration,the restoration integrity and abutment fracture free effect of Ceramage resin inlay group were better than those of resin filling group(P<0.05).The rate of shedding of restoration in Ceramage resin inlay group[5.56％(1/18)]was lower than that in resin filling group[40.91％(9/22)],and the difference was statistically sig-nificant(P<0.05).Conclusion The short-term repair effect of Ceramage resin inlay and resin filling is similar in the repair of immature permanent molars with serious tooth defects;however,the long-term repair effect of Ceramage resin inlay is better than that of direct resin filling.
