儿童乳磨牙和年轻恒磨牙窝沟以其独特的解剖和生理特点，为细菌的生长定植，菌斑的集聚提供了一个微生态环境，从而导致牙面脱矿和龋的发生，其中又以窝沟龋占绝大多数。窝沟封闭术是儿童窝沟龋最有效的预防方法之一，临床上常用的窝沟封闭术有常规窝沟封闭术（CST）和釉质窝沟封闭术（EST）。 EST的应用明显地提高了封闭剂的黏结面积，增强了封闭剂在牙面上的黏结性、渗透性和密合性，既提高了窝沟封闭剂的保留率和防龋效果，还可及时地发现窝沟早期龋和隐匿龋，明显地提高了窝沟封闭剂的保留率，其防龋效果优于CST。本文就窝沟封闭术的临床应用和窝沟封闭术的防龋效能等研究进展作一综述，旨在为儿童窝沟封闭术的操作提供部分参考。

Dental fissure in children has unique anatomical and physiological features, which provide a micro-e-cological environment for the growth of bacteria colonization and plaque accumulation, and then will result in dem-ineralization of teeth surfaces and occurrence of caries, and pit and fissure caries accounts for the vast majority of them. The pit and fissure sealant technique has become one of the most effective prevention methods. At present, the clinical dentists usually use enameloplasty sealant technique(EST), or conventional sealant technique(CST) to prevent caries happening. The application of EST can be preferred to CST for improving adhesion, adaptation, pen-etration and the remaining rate of the sealant within the fissure system, and also has less microleakage. Thus enameloplasty has been implicated in the successful application of pit and fissure sealants. The following words will discuss about the research progress in efficiency and application of the pit and fissure sealant, in order to ap-ply reference to the operation in children.
