氟為什麼可以預防齲病的發生?


    氟為什麼可以預防齲病的發生?



    氟為什麼可以預防齲病的發生?牙齒處於複雜的口腔環境中,經常會受到細菌和某些酸性物質的侵襲。

    

    氟可以通過下麵多種途徑發揮防齲作用,達到保護牙齒的目的。

    (1)氟可以抑制致齲細菌的生長繁殖,阻礙細菌與菌斑在牙面的堆積和黏附,影響菌斑形成。氟還可以抑制酶的活性以及細菌的產酸能力,減少齲病的發生。

    

    (2)氟能夠進入牙釉質中,使釉質變得結實,在酸中也不溶解,從而增強了牙齒的抗齲力。

    

    (3)氟可以促進牙釉質的再礦化,從而促進早期齲損的修復和重建。

    

    (4)氟還可以使牙齒外形更有利於自潔作用,如窩溝裂隙較淺,牙尖較圓等。
