1、1會計學dd牙髓病和根尖周病治療概述牙髓病和根尖周病治療概述 Cotton rollsSaliva evacuatorSaliva ejectorsulp capping is defined as “endodontic treatment designed to maintain the vitality of the endodontium”.Antibacterial activity中和炎癥所產(chǎn)生的酸中和炎癥所產(chǎn)生的酸性產(chǎn)物性產(chǎn)物Activate AKP, promote dentin formation激活堿性磷酸酶，促進修復性牙本質形成激活堿性磷酸酶，促進修復性牙本質形成Pulp

2、 capping implies placing the dressing directly onto the pulp exposure.原原 理理 用蓋髓劑用蓋髓劑覆蓋在露髓創(chuàng)面上，消除覆蓋在露髓創(chuàng)面上，消除炎癥和感染，保護牙髓組織，使其恢炎癥和感染，保護牙髓組織，使其恢復健康。復健康。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 窩洞中遺留的少量細菌被蓋髓劑覆蓋窩洞中遺留的少量細菌被蓋髓劑覆蓋，及細菌產(chǎn)酸所需的底物被隔絕而大幅度，及細菌產(chǎn)酸所需的底物被隔絕而大幅度下降，下降，Ca(OH)2可維持局部的堿性環(huán)境，可維持局部的堿性環(huán)境，有利于修復性牙本質的形成。有利于修復性牙本質的形成。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活髓切斷術活髓切斷術 是通過臨床征象確定切除組織的深度，去除有病變的冠髓，以蓋髓劑覆蓋于牙髓斷面，保存未感染根髓的治療方法 Pulpotomy implies the removal of coronal pulp tissue to the level of healthy pulp.This plan of action
