牙齿健康 身体棒棒 Good teeth Good health

      9月20日是全国爱牙日，9月26日我校携手都江堰市幸福街道卫生服务中心开展了“牙齿健康  身体棒棒”的爱牙讲座活动。

      September 20th is the national tooth loving day. On September 26th, our school carried out the "Good teeth  Good health" tooth lecture activities with  Dujiangyan Xingfu Street Health Service Center.

      通过活动，孩子们认识到牙齿的重要性，并且了解了目前对他们而言最普遍的口腔疾病——龋病（俗称虫牙、蛀牙）。龋病的图片触目惊心，孩子们纷纷检查自己的牙齿是否患龋病。

      Through activities, children realize the importance of teeth and the most common oral disease for them at present. Pictures of dental caries are shocking. Children check their teeth for dental caries.

      若牙齿已患龋病，一定要及时到牙科进行诊治。那若想要预防龋病，该怎么办呢？首先，要正确刷牙；其次，可以通过窝沟封闭来预防龋病。If the teeth have caries, we must timely diagnosis and treatment. What should we do to prevent caries? First of all, we should brush our teeth correctly; secondly, we can prevent dental caries through pit and fissure closure.

      窝沟封闭是指不损伤牙体组织，将窝沟封闭材料涂布于牙冠咬合面、颊舌面的窝沟点隙，当它流入并渗透窝沟后固化变硬，形成一层保护性的屏障，覆盖在窝沟上，能够阻止致龋菌及酸性代谢产物对牙体的侵蚀，以达到预防窝沟龋的方法。窝沟封闭是一种无痛、无创伤的预防方法。Sealing pit and fissure is a method to prevent dental caries by preventing the erosion of cariogenic bacteria and acid metabolites. Pit and fissure closure is a painless and non-invasive method of prevention.

      Good teeth, good health, let's protect our teeth together!
