Objective To study the clinical effects of different bioactive pulp capping materials used in the treatment of immature permanent teeth with irreversible pulpitis.Methods A total of 126 children(142 immature permanent teeth)diagnosed with irrecoverable pulpitis were selected from the Stomatology Department of Qinhuangdao Harbor Hospital from December 2021 to December 2022.They were numbered according to the order of treatment and randomly divided into 3 groups,Group A(42 cases,49 teeth)were treated with iRoot BP Plus pulpotomy,Group B(42 cases,46 teeth)were treated with Biodentine pulpotomy,and Group C(42 cases,47 teeth)were treated with mineral trioxide condensate(MTA)pulpotomy.Visual analogue scale(VAS)was used to evaluate the pain degree of the children in each group at 24 and 72 hours after surgery,and the success rate,dentin bridge formation rate,tooth discoloration rate and gingival health status of the three groups were compared at 3,6 and 12 months after surgery to evaluate the efficacy of the three groups.Results No moderate or severe pain occurred in all groups at 24h and 72h after operation,and there was no significant difference in the incidence of mild pain at 24 h among all groups(P>0.05).There were no significant differences in the success rate,dentin bridge formation rate or gingival health status among all groups during the same follow-up period(P>0.05).During the follow-up period,the discoloration rate of teeth in each group was recorded 3 months,6 months and 12 months after surgery as follows,3 months:Group A(0%),Group B(2.22%),Group C(45.65%),6 months:Group A(2.17%),Group B(2.44%),Group C(54.55%),12 months:Group A(4.55%),Group B(4.88%),Group C(69.77%),there was no significant difference between Group A and Group B(P>0.05),the differences between group A and group C,group B and group C were statistically significant(P<0.05).Conclusions The application of bioactive pulp capping materials in the treatment of immature permanent teeth with irrevocable pulpitis has low incidence of postoperative pain,mild degree,satisfactory clinical effect and no significant difference.The tooth discoloration rate of iRoot BP Plus and Biodentine is significantly lower than that of MTA.
