Abstract：Objective To evaluate the clinical efficacy of vital pulp therapy using different endodontic biomaterials Min-eral Trioxide Aggregate(MTA)and iRoot BP Plus in mature permanent teeth with carious pulp exposure.Methods From October 2020 to May 2023,200 teeth with carious pulp exposure in mature permanent teeth were selected from the Department of Cariology and Endodontology,Hohhot Stomatological Hospital.The teeth were randomly divided into two groups,MTA group(n=100)and iRoot BP Plus group(n=100),different treatment methods of vital pulp preservation were selected according to the bleeding condition and capped with MTA or iRoot BP Plus according to the group.The clinical efficacy,occurrence of dentin bridge,tooth discoloration,pulp cavity calcification and root resorption,visual ana-logue scale(VAS)score and satisfaction were compared between the two groups.Results At 12 months after treatment,the success rate of treatment in the iRoot BP Plus group was 87％(87/100),which was significantly higher than that in the MTA group(72％),and the difference was statistically significant(x2=6.903,P=0.014).At 3,6 and 12 months af-ter operation,the formation rates of dentin bridge were 5％(5/100),36％(36/100)and 45％(45/100)in MTA group and 8％(8/100),42％(42/100)and 53％(53/100)in iRoot BP Plus group,respectively,and the differences were not statisti-cally significant(all P＞0.05).At 3,6 and 12 months af-ter operation,the incidence of teeth discoloration in the MTA group were 16％(16/100),28％(28/100),and 46％(46/100),respectively,while none of the teeth in the iRoot BP Plus group showed tooth discoloration(0％),and the differences were statistically significant(all P＜0.05).At 24 h after operation,there was no significant difference in VAS score between the two groups(P＞0.05).At 12 months af-ter operation,there was no significant difference in patient satisfaction between the two groups(P＞0.05).Conclusion The clinical efficacy of vital pulp therapy for management of carious pulp exposure in mature permanent teeth is good.Compared with MT A,iRoot BP Plus has a higher success rate of treatment as a pulp capping agent,and it is not easy to cause tooth discoloration,which has a broad clinical application prospect.
