Abstract：Objective To observe the efficacy of the bioceramic material iRoot BP Plus in vital pulpotomy for irreversible pulpitis of mature permanent teeth.Methods A total of 100 patients(100 affected teeth)with irreversible pulpitis of mature permanent teeth admitted to the School of Stomatology,Xi'an Jiaotong University from March 2022 to March 2024 were selected as the study subjects.They were divided into a control group and an experimental group by simple randomization,with 50 cases in each group(50 affected teeth each).The control group underwent pulpotomy using mineral trioxide aggregate(MTA)as the pulp capping agent,while the experimental group underwent pulpotomy using the bioceramic material iRoot BP Plus as the pulp capping agent.Pain level,clinical efficacy,radiographic efficacy,and tooth discoloration rate were compared between the two groups.Results On the first and seventh days after surgery,the visual analog scale(VAS)scores of both groups decreased compared with those before surgery(P<0.05),and the scores on day 7 were lower than those on day 1(P<0.05).The VAS scores of the experimental group were lower than those of the control group on both day 1 and day 7 after surgery(P<0.05).At 3,6,and 12 months after surgery,the clinical success rates of the experimental group were 96.00%,94.00%,and 94.00%,respectively,while those of the control group were 94.00%,92.00%,and 90.00%,respectively,with no statistically significant differences between the two groups(P>0.05).At 3,6,and 12 months after surgery,the radiographic success rates of the experimental group were 96.00%,92.00%,and 92.00%,respectively,while those of the control group were 92.00%,90.00%,and 90.00%,respectively,with no statistically significant differences between the two groups(P>0.05).At 12 months after surgery,the tooth discoloration rate of the experimental group was 2.00%(1/50),which was lower than that of the control group at 46.00%(23/50)(χ²=26.535,P<0.05).Conclusion In vital pulpotomy for irreversible pulpitis of mature permanent teeth,the short-term and long-term efficacy of iRoot BP Plus is comparable to that of MTA,but it shows advantages in reducing postoperative pain and preventing tooth discoloration.
