两种材料用于年轻恒牙直接盖髓的临床疗效

Outcomes of direct pulp capping with different materials in young permanent teeth

目的:比较iRoot BP Plus和三氧化矿物聚合体(MTA)两种材料在年轻恒牙直接盖髓中的疗效差异。方法:将60颗深龋去腐净后露髓患牙随机分为两组,每组30颗;分别采用iRoot BP Plus和MTA进行直接盖髓术,术后3、6、12个月复诊时分别记录患牙临床及影像学检查情况。结果:术后1年iRoot BP Plus组和MTA组治疗成功率分别为96.7%和93.3%,差异无统计学意义(P>0.05)。iRoot BP Plus组患牙均未见牙齿变色,MTA组有18颗患牙观察到牙齿变色(P<0.01)。结论:年轻恒牙深龋露髓直接盖髓术中iRoot BP Plus与MTA临床疗效相近,但iRoot BP Plus操作较为便利且无牙齿变色现象,是临床上更为理想的直接盖髓材料。

Objective:To evaluate the effect of iRoot BP Plus and mineral trioxide aggregate(MTA)as a capping material for pulp tissue in young permanent teeth.Methods:Sixty young permanent teeth were randomly divided after caries excavation into 2 groups that iRoot BP Plus and MTA(30 teeth in each group).Exposed pulps were capped using standardized protocols.The treated teeth were restored with glass ionomer cement and composite restoration.The outcome was success rate at the 12-month follow-up.Clinical and radiographic evaluations were performed at 3,6,and 12 months after treatment.Results:The success rate was 96.7% for iRoot BP Plus and 93.3% for MTA(P>0.05).Gray discoloration was observed in 18 teeth only with MTA(P<0.01).Conclusion:iRoot BP Plus and MTA had similar favourable results when used as direct pulp-capping agents for cariously exposed young permanent teeth.However,iRoot BP Plus showed no any cause any gray discoloration in this study.
