窩溝封閉
窩溝封閉 （英語：fissure sealants[1][2]）是一個牙醫學上為防止齲齒將窩溝封閉材料塗佈於牙冠咬合面、頰舌面的窩溝點隙上的方法。主要用於易蛀牙的兒童，在兒童換出恆臼齒後即可進行。
背景
大牙的咬合面上凹陷的部位叫窩溝。如果窩溝非常深，食物和細菌嵌塞進去，就容易發生窩溝齲。
窩溝封閉不損傷牙體組織，是一種無痛、無創傷的預防窩溝齲的方法[3] 。
窩溝封閉材料滲透進窩溝後，固化變硬，形成一層保護性的屏障，覆蓋在窩溝上。
歷史
第一次防止齲齒的嘗試是1905年米勒將硝酸銀塗到牙齒表面，以防止齲齒[4]。
操作
窩溝封閉可分為清潔牙齒、酸蝕、沖洗乾燥、塗布封閉劑和固化幾個步驟。[5][6][7]
效果
窩溝封閉是預防窩溝齲的有效方法。[8]
