硅酸钙类盖髓剂用于深龋恒牙直接盖髓的临床疗效观察

Clinical efficacy of direct pulp capping with calcium silicate cements in permanent teeth

目的:观察硅酸钙类盖髓剂iRoot BP Plus、TheraCal LC和MTA在深龋露髓恒牙直接盖髓术中的临床疗效及牙本质钙化桥形成情况。方法:将57颗去腐露髓的恒牙随机分为3组,分别采用iRoot BP Plus、TheraCal LC和MTA行直接盖髓术。分别于术后1、3、6、12个月复查,观察各组盖髓成功率和牙本质钙化桥形成情况。结果:术后12个月复查,iRoot BP Plus、TheraCal LC和MTA组治疗成功率分别为89.47%、84.21%和89.47%,3组之间差异无统计学意义(P>0.05)。iRoot BP Plus和TheraCal LC组均未出现充填部位变色。MTA组68.72%患牙出现充填部位变色。术后3、6、12个月,iRoot BP Plus、TheraCal LC和MTA组钙化桥形成率组间差异均无统计学意义(P>0.05)。结论:硅酸钙类盖髓剂iRoot BP Plus、TheraCal LC和MTA临床疗效相当,值得临床推广应用。

Objective:To observe the clinical efficacy of direct pulp capping with iRoot BP Plus, TheraCal LC and mineral trioxide aggregate(MTA)in permanent teeth with deep caries.Methods:Totally 57 permanent teeth with deep caries were randomly divided into three groups.iRoot BP Plus, TheraCal LC and MTA were used to direct cap on the exposed pulp respectively.Clinical efficacy and dentin calcification bridge formation were evaluated.Results:At 12 month recall, the survival rates of the pulp in iRoot BP Plus, TheraCal LC and MTA groups were 89.47%,84.21% and 89.47% respectively.There was no significant difference among the three groups(P>0.05).There was no discoloration of the filling sites in iRoot BP plus and TheraCal LC groups.In MTA group, 68.72% of the teeth had discoloration of the filling sites.There was no significant difference in the formation rate of calcified bridge among iRoot BP plus, TheraCal LC and MTA groups at 3, 6 and 12 months recalls(P>0.05).Conclusion:The clinical efficacy of the three calcium silicate cements was similar, which is worthy of clinical application.
