【摘要】 龋病是儿童口腔疾病中最常见的一种，尤其是窝沟龋，由于唾液无法流入窄深裂隙中而缺乏冲刷作用，且再矿化制剂目前较少用于儿童口腔预防及治疗，故其具有患病率高、治疗率低的特点。基于全酸蚀技术的发展，学者于20世纪50年代提出了窝沟封闭的概念，即在牙齿表面窝沟点隙处覆盖一层封闭材料，通过建立物理屏障来隔绝细菌入侵，增强牙齿表面的自洁作用，保护牙体组织。数十年来，不仅儿童隔湿技术和窝沟封闭材料得到了很大发展，激光等牙面预处理方法的应用也提高了窝沟封闭剂的保留率和抗龋率。儿童牙科患者成功治疗还依赖有效的沟通，并根据患儿的治疗需求制定个性化行为指导。综合各个方面，现今窝沟封闭技术逐渐成熟，已成为预防窝沟龋发生的最有效措施之一。文章主要围绕其技术进展、操作流程、注意事项进行综述，以期为儿童牙科医生相关临床操作提供参考。更多还原

【Abstract】 Caries is one of the most prevalent chronic diseases of children worldwide, especially pit and fissure caries. Because of the inability of saliva to flow into narrow fissures, it lacks the washing effect, and remineralization agents are currently not widely used in pediatric oral treatment, so it is characterized by high prevalence and low treatment rate. Scholars proposed the concept of pit and fissure sealant in the 1950s, whereby the pit and fissures are covered with sealing material, then isolate bacterial invasion by establishing a physical barrier,which enhance the self-cleaning function of the tooth and then protect the dental tissue. Over the decades, not only have the techniques of moisture isolation and sealing materials been greatly developed, but the application of laser and other pretreatment methods on tooth surface has also improved the retention rate and anticaries rate of sealants.The successful treatment of pediatric dental patients also depends on effective communication and the formulation of personalized behavior guidance according to the treatment needs of child.Integrating all the aspects,current pit and fissure sealing technology has matured and become one of the most effective measures to prevent the occurrence of pit and fissure caries.The article mainly focuses on the review of technical progress,operation procedures and precautions,with a view to providing reference for pediatric dentists in clinical operations.更多还原
