摘　　要：目的 探讨生物陶瓷材料iRoot BP Plus和三氧化矿物聚合体(mineral trioxide aggregate,MTA)应用于成熟恒牙直接盖髓术的效果,为临床提供参考。方法 因深龋或可复性牙髓炎去腐后露髓的成熟恒牙75颗,患者74例,随机分为两组,每组37例患者,试验组使用iRoot BP Plus(iRoot组),对照组使用MTA(MTA组)作为盖髓剂。术后1、3、6、12个月进行临床评价及影像学分析。比较两组治疗成功率,并分析性别、年龄、牙位、洞型、穿髓孔数目、大小等因素对直接盖髓术疗效的影响。结果 12个月后完成复诊60例患者61颗患牙(i Root组30例患者31颗,MTA组30例患者30颗),iRoot组的成功率90.3%,MTA组成功率为90.0%,两组成功率差异无统计学意义(P>0.05),性别、年龄、牙位、洞型、穿髓孔数目、大小等因素对两组疗效的影响均无统计学意义(P>0.05)。结论 iRoot BP Plus与MTA用于因龋露髓成熟恒牙直接盖髓术效果均良好,但iRoot操作较为简便。Objective To study the clinical efficacy of biological ceramics(iRoot BP Plus) and mineral trioxide aggregate(MTA) in direct pulp capping of mature permanent teeth,to provide referrence for clinical application.Methods Seventy-four patients with pulp exposure due to deep caries or reversible pulpitis in 75 mature permanent teeth were selected and were randomly divided into two groups.iRoot BP Plus were used as pulp capping agents in the treatment group and MTA were used as pulp capping agents in the control group respectively.The clinical efficacy and imaging analysis were performed at 1,3,6 and 12 months after operation.Treatment success rate of the two groups were calculated,and the influence of various factors including gender,age,tooth position,cavity,number and size of pulp exposure on the efficacy of direct pulp capping were analyzed.Results Sixty patients with 61 mature permanent teeth were selected.Twelve mouths after treatment,61 teeth of 60 patents were completely investigated(iRoot group:31 teeth30 patients;MTA group:30 teeth 30 patients).The success rates of the 2 groups were 90.3%(iRoot BP Plus) and90.0%(MTA),respectively.There was no statistical difference between 2 groups(P>0.05).Statistical analysis also showed that gender,age,tooth position,cavity,number and size of pulp exposure had no significant difference between the two groups(P>0.05).Conclusion Both iRoot BP Plus and MTA are effective in direct pulp capping of mature permanent teeth with carious pulp exposure,while the operation of iRoot is simple and convenient.
