MTA直接盖髓术治疗年轻恒牙露髓效果观察

Effect observation on MTA direct pulp capping in the treatment of young permanent teeth with pulp exposure

目的探究矿物三氧化物凝聚体(MTA)直接盖髓术治疗年轻恒牙露髓临床效果。方法 34例年轻恒牙牙髓外露患儿,随机分为观察组与对照组,每组17例。对照组使用氢氧化钙糊剂实施直接盖髓术,观察组使用MTA直接盖髓术。随访1年,对比治疗效果。结果观察组患儿成功率为94.12%,高于对照组的64.71%,差异有统计学意义(P<0.05)。结论对于年轻恒牙露髓患儿使用MTA作为直接覆盖术材料进行治疗,效果比氢氧化钙糊剂要好,安全性强,患儿耐受程度高,具有良好的生物相容性和封闭性,值得进一步推广使用。

Objective To explore the clinical effect of mineral trioxide aggregate (MTA) direct pulp capping in the treatment of young permanent teeth with pulp exposure. Methods A total of 34 young permanent teeth with pulp exposure children were randomly divided into observation group and control group, with 17 cases in each group. The control group received calcium hydroxide paste for direct pulp capping, and the observation group received MTA direct pulp capping. Treatment effect was compared in two groups after 1 year of follow-up. Results The observation group had higher success rate as 94.12% than 64.71% in the control group, and the difference had statistical significance (P<0.05). Conclusion For young permanent teeth with pulp exposure children, MTA as direct pulp capping material for treatment shows better effect than calcium hydroxide paste with strong security,high degree of tolerance in children, good biocompatibility and closeness. So it is worth further promotion and and use.
