新型生物陶瓷材料用于年轻恒牙牙髓切断术中的临床价值

Clinical value of new bioceramic materials for young permanent teeth pulpectomy

目的:探讨新型生物陶瓷材料应用于年轻恒牙牙髓切断术中的临床价值。方法:选取40例外伤冠折牙髓外露患儿作为研究对象,患儿均需行牙髓切断术治疗,采用随机数字表法分为研究组和对照组,每组20例。两组均予年轻恒牙牙髓切断术治疗,研究组采用三氧化矿物凝聚体作为盖髓剂,对照组采用氢氧化钙作为盖髓剂,比较两组临床疗效,术后不良反应发生率及患牙存活情况。结果:研究组患儿临床总有效率为95.00%,高于对照组的60.00%,差异有统计学意义(P<0.05);研究组术后充填物异常、根尖周炎发生率均低于对照组,差异有统计学意义(P<0.05);随访2年,研究组患牙存活率为95.00%,高于对照组的60.00%,差异有统计学意义(P<0.05)。结论:在年轻恒前牙牙髓切断术中应用三氧化矿物凝聚体,有利于保障患儿治疗效果,还可提高随访期间患牙存活率。

Objective:To explore clinical value of new bioceramic materials for young permanent teeth pulpectomy.Methods:40 children with dental crown fractured caused by trauma and exposed pulps were selected as the research subjects.All the children needed pulpectomy.They were divided into study group and control group according to the random number table method,20 cases in each.Both groups were treated with pulpectomy for the young permanent teeth.Besides,the study group used mineral trioxide aggregate as pulp capping agents,while the control group used calcium hydroxide as the pulp capping agents.The clinical efficacy,incidence of postoperative adverse reactions and survival of the affected teeth were compared between the two groups.Results:The total clinical effective rate in the study group was 95.00%,which was higher than the control group of 60.00%,and the difference was statistically significant(P<0.05).The incidence rates of abnormal fillers and periapical periodontitis in the study group were lower than those in the control group,and the differences were statistically significant(P<0.05).After 2 years of followup,the survival rate of the affected teeth in the study group was 95.00%,which was higher than the control group of 60.00%,and the difference was statistically significant(P<0.05).Conclusions:The mineral trioxide aggregate for the young permanent teeth pulpectomy is beneficial to guarantee the treatment effect of the children and can also improve the survival rate of the affected teeth during the follow-up period.
