Sealants are a successful tool in caries prevention, but their role in preventive strategies after the caries decline has to be discussed. A survey of paediatric departments across Europe revealed that indications for pit and fissure sealants vary considerably, both nationally and internationally. Evidence for effectiveness of sealants in controlling caries in posterior teeth implies that sealants should be an integrated part of management of pit and fissure caries. Still, the indication for occlusal sealants seems to be shifting from primary prevention to a therapeutic decision for caries management of lesions in enamel and the outer part of the dentine. Sealants are also an interesting concept for caries management in approximal surfaces. Clinical trials suggest that novel techniques of sealing or infiltrating approximal lesions show promise. However, approximal sealing techniques are as complex to apply and time-consuming as approximal fillings. The article proposes guidelines for teaching on the use of sealants.
窝沟封闭剂是龋病预防的有效工具，但在龋病减少后，其在预防策略中的作用仍需讨论。一项对欧洲儿科部门的调查显示，窝沟封闭剂的适应证在国内外差异很大。窝沟封闭剂在控制后牙龋病方面的有效性证据表明，窝沟封闭剂应该成为窝沟龋病管理的一个组成部分。然而，窝沟封闭剂的适应证似乎正在从初级预防转变为对牙釉质和牙本质外层龋损进行治疗性决策的龋病管理。窝沟封闭剂也是邻面龋病管理的一个有趣概念。临床试验表明，用于封闭或渗透邻面病变的新技术有一定前景。然而，邻面封闭技术的应用和耗时与邻面填充一样复杂。本文提出了窝沟封闭剂使用教学指南。
