1、1會計(jì)學(xué)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(jìn)修復(fù)性牙本質(zhì)形成激活堿性磷酸酶，促進(jìn)修復(fù)性牙本質(zhì)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(hù)牙髓組織，使其恢炎癥和感染，保護(hù)牙髓組織，使其恢復(fù)健康。復(fù)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(xì)菌被蓋髓劑覆蓋窩洞中遺留的少量細(xì)菌被蓋髓劑覆蓋，及細(xì)菌產(chǎn)酸所需的底物被隔絕而大幅度，及細(xì)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(fù)性牙本質(zhì)的形成。有利于修復(fù)性牙本質(zhì)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(shù)活髓切斷術(shù) 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
