盖髓术是一种保髓的生物学疗法。盖髓剂的药物性能是其成败的关键性问题之一。自1984年6月以来,我们用硝酸钾盖髓318例,并通过成年人错位、阻生等废用患牙的病理组织学观察,对其作用机理作了初步研究。现将记录资料完整、随诊复查的304例(325颗患牙)的临床疗效及该剂对牙髓组织影响的病理组织学变化观察总结如下。
Gai pulp surgery is a cardinal biological therapy. The medical properties of capping agents are one of the key issues of its success. Since June 1984, 318 cases of pulp capping have been treated with potassium nitrate and the mechanism of action has been preliminarily studied through histopathological observation of disused and impacted adult teeth. The record is now complete, follow-up review of 304 cases (325 teeth) clinical efficacy and the agent on the pulp tissue histological changes observed as follows.
