Objective To compare the effects of three different dental restoration materials. Methods A total of 120 patients who underwent oral repair in our hospital from January 2020 to November 2021 were randomly divided into group A, group B and group C, with 40 cases in each group. Group A was repaired with ceramic materials, group B was repaired with resin materials, and group C was repaired with metal materials. The success rate of repair and the incidence of adverse reactions were compared among the three groups. Results There was no significant difference in the success rate of repair between the three groups at 6 and 12 months after repair (P>0.05). The incidence of adverse reactions in group A was 7.50%, which was lower than 40.00% in group B and 22.50% in group C, the difference was statistically significant (P
