Pellicle考過:
沒有結構,沒有細胞的有機質層
具保護牙釉質功能
可減少牙齒之間的磨擦(friction)
來自唾液中的蛋白質,含免疫球蛋白IgE
在清洗牙齒後二小時內會完全覆蓋牙齒表面
可作為牙齒再礦化之基質

Within 2 hours, a cell-free, organic film, the acquired enamel pellicle (AEP), can cover the previously denuded area completely. The pellicle is formed primarily from the selective precipitation of various components of saliva, particularly selective enzymes. The functions of the pellicle are believed to be (1) to protect the enamel, (2) to reduce friction between teeth, and (3) to provide a matrix for remineralization.
後天性牙釉質薄膜(acquired enamel pellicle)由無細胞的有機膜所構成。而這個薄膜由唾液中成分選擇性沉澱。功能有:
(1) 保護牙釉質(enamel)
(2)減少牙齒間的摩擦力 --> (C)錯誤
(3) 提供再礦化(remineralization)的基質
