直接盖髓术是用药物覆盖暴露的牙髓,以促进牙髓愈合和修复的治疗.通常仅适应于健康牙髓的新鲜暴露病例,对于因龋病露髓的患牙则不宜应用.近年,不少学者报道对去龋露髓的患牙采用直接盖髓术也取得了较好效果,其疗效不低于健康露髓牙.本研究是对临床无明显症状或症状轻微的深龋露髓年轻恒磨牙,进行直接盖髓术,试图探讨保留全部活髓的临床疗效,并对观察中的失败病例在改变治疗时进行牙髓的临床病理学研究.
Direct pulp capping is the use of drugs to cover the exposed pulp to promote healing and repair of the pulp.Usually only adapted to freshly exposed cases of healthy pulp, dental caries for the exposed pulp is unfit for use.In recent years, Many scholars reported that dental pulp to caries exposed pulp using direct pulp capping also achieved good results, its efficacy is not less than healthy dew pulp.This study is no clinical symptoms or mild symptoms of caries exposed pulp Young permanent molars were treated with direct pulp capping to explore the clinical efficacy of preserving all viable pulp and to investigate the clinicopathological studies of pulp during changing treatment when failure was observed.
