1、1会计学dd牙髓病和根尖周病治疗概述牙髓病和根尖周病治疗概述 Cotton rollsSaliva evacuatorSaliva ejectorsulp capping is defined as “endodontic treatment designed to maintain the vitality of the endodontium”.Antibacterial activity中和炎症所产生的酸中和炎症所产生的酸性产物性产物Activate AKP, promote dentin formation激活碱性磷酸酶，促进修复性牙本质形成激活碱性磷酸酶，促进修复性牙本质形成Pulp

2、 capping implies placing the dressing directly onto the pulp exposure.原原 理理 用盖髓剂用盖髓剂覆盖在露髓创面上，消除覆盖在露髓创面上，消除炎症和感染，保护牙髓组织，使其恢炎症和感染，保护牙髓组织，使其恢复健康。复健康。For a direct pulp capping procedure, a calcium hydroxide lining material is placed on the exposed pulpal tissue and a small amount of surrounding dentin.

3、A sealing liner and/or a sealing restoration is then placed to seal out bacteria and their by-products.原原 理理 窝洞中遗留的少量细菌被盖髓剂覆盖窝洞中遗留的少量细菌被盖髓剂覆盖，及细菌产酸所需的底物被隔绝而大幅度，及细菌产酸所需的底物被隔绝而大幅度下降，下降，Ca(OH)2可维持局部的碱性环境，可维持局部的碱性环境，有利于修复性牙本质的形成。有利于修复性牙本质的形成。In an indirect pulp capping procedure, demineralized dentin is

4、 removed in the periphery of the preparation, but a small amount of demineralized dentin is left immediately over the area of the pulp. A calcium hydroxide lining material is placed to cover the remaining demineralized dentin. A sealing liner and/or a sealing restoration is then placed to seal out bacteria and their by-products. Pulpotomy活髓切断术活髓切断术 是通过临床征象确定切除组织的深度，去除有病变的冠髓，以盖髓剂覆盖于牙髓断面，保存未感染根髓的治疗方法 Pulpotomy implies the removal of coronal pulp tissue to the level of healthy pulp.This plan of action
