iRoot BP Plus与MTA在恒牙深龋直接盖髓术中的临床疗效比较

Comparison of clinical efficacy of iRoot BP Plus and MTA in direct pulp capping of deep caries in permanent teeth

目的比较iRoot BP Plus与三氧化矿物聚合体(MTA)在恒牙深龋直接盖髓术中的临床疗效。方法选取82例单颗恒牙深龋露髓患者为研究对象,根据使用盖髓剂不同分为对照组和观察组,各41例。观察组采用iRoot BP Plus直接盖髓,对照组采用MTA直接盖髓。比较两组术后不同时间点治疗成功率,直接盖髓操作时间,钙化桥形成情况及牙冠变色发生情况。结果所有患者术后均连续随访12个月,无失访病例。观察组术后3、6、12个月治疗成功率分别为97.56%、97.56%、95.12%,对照组为95.12%、92.68%、92.68%;两组术后3、6、12个月治疗成功率比较差异均无统计学意义(P>0.05)。观察组患者直接盖髓操作时间为(2.58±0.40)min,对照组为(4.42±0.56)min;观察组患者直接盖髓操作时间短于对照组,差异有统计学意义(t=17.120,P=0.000<0.05)。术后连续随访12个月,观察组钙化桥总形成率为95.12%,对照组为90.24%,两组钙化桥总形成率比较差异无统计学意义(P>0.05);观察组牙冠变色率为0,低于对照组的56.10%,差异有统计学意义(P<0.05)。结论iRoot BP Plus与MTA应用于恒牙深龋直接盖髓术中均具有显著的临床疗效,能提高治疗成功率,但iRoot BP Plus在减少操作时间、避免牙冠变色方面更具优势,是临床上更为理想的直接盖髓剂。

Objective To compare the clinical efficacy of iRoot BP Plus and mineral trioxide aggregate(MTA)in direct pulp capping of deep caries in permanent teeth.Methods A total of 82 patients with single permanent teeth with deep caries and pulp exposure were selected as the study subjects and divided into a control group and an observation group according to different pulp capping agents,with 41 cases in each group.The observation group received iRoot BP Plus for direct pulp capping,and the control group received MTA for direct pulp capping.Both groups were compared in terms of treatment success rates at different postoperative time points,operation time of direct pulp capping,calcification bridge formation and crown discoloration.Results All patients were followed up continuously for 12 months after surgery,and no cases were lost to follow-up.The treatment success rates were 97.56%,97.56%and 95.12%in the observation group,and 95.12%,92.68%and 92.68%in the control group,respectively.There was no statistically significant difference in treatment success rate at 3,6 and 12 months after surgery between the two groups(P>0.05).The operation time of direct pulp capping was(2.58±0.40)min in the observation group and(4.42±0.56)min in the control group.The operation time of direct pulp capping in the observation group was shorter than that in the control group,and the difference was statistically significant(t=17.120,P=0.000<0.05).After 12 months of follow-up after surgery,the total rate of calcification bridge formation was 95.12%in the observation group and 90.24%in the control group,and the difference was not statistically significant when comparing the two groups(P>0.05).The rate of crown discoloration in the observation group was 0,which was lower than 56.10%in the control group,and the difference was statistically significant(P<0.05).Conclusion The application of iRoot BP Plus and MTA in direct pulp capping of deep caries has significant clinical efficacy and can improve the success rate of treatment.However,iRoot BP Plus has more advantages in reducing operation time and avoiding crown discoloration,and is a more ideal direct pulp capping agent in clinical practice.
