Abstract：Objective To compare the clinical efficacy of iRoot BP Plus and self-setting calcium phosphate paste in pulpotomy of primary molars.Methods Ninety-six children with deep caries near the pulp or early pulpitis in primary molars were included.All underwent pulpotomy and were randomly divided into the iRoot BP Plus group(n=48,using iRoot BP Plus as a capping material)and the self-setting calcium phosphate paste group(n=48,using self-set-ting calcium phosphate paste as a capping material).Surgical success rates,postoperative reactions,and gingival health[gingival index(GI)and sulcus bleeding index(SBI)]were compared between the two groups.Results There were no significant differences in surgical success rates between the groups at 3 and 6 months postoperatively(P＞0.05).Howev-er,at 12 months,the iRoot BP Plus group had a significantly higher success rate(P＜0.05).At 3 and 6 months postop-eratively,the incidence of complications such as tooth mobility,percussion pain,incomplete sinus tract,occlusal dysfunc-tion,abnormal pulp vitality,dentin abnormalities,and apical lesions showed no significant differences between the groups(P＞0.05).At 12 months,the iRoot BP Plus group exhibited a lower complication rate(8.33％)compared to the self-setting calcium phosphate paste group(22.92％,P＜0.05).The iRoot BP Plus group had significantly lower GI and SBI scores at 6 and 12 months postoperatively compared to the self-setting calcium phosphate paste group(P＜0.05).Conclusion Both iRoot BP Plus and self-setting calcium phosphate paste achieved satisfactory results in pulpotomy of primary molars.However,iRoot BP Plus demonstrated higher success rates,lower postoperative reaction rates,and supe-rior pulp health recovery at 12 months postoperatively.
