什麽時候進行窩溝封閉

  什麽時候進行窩溝封閉

  什麽時候進行窩溝封閉,從理論上講,乳牙和恒牙都應進行窩溝封閉,但臨床應用最多的是剛萌出恒磨牙的窩溝封閉。人一般在6歲左右萌出第一顆恒磨牙,第12歲左右萌出第二顆恒磨牙。通常情況下,在磨牙萌出後一年之內,讓孩子做窩溝封閉的效果最好。因爲新萌出的牙齒表層鈣化不足,耐酸性差,容易發生齲齒。加上剛萌出的牙齒表面窩溝深,封閉劑不易脫落,防齲效果最好。如果已經出現了齲齒,窩溝封閉就沒有意義了,這時需要的是充填治療。因爲沒有磨除牙體組織,所以窩溝封閉沒有痛苦。進行窩溝封閉的全過程孩子不會有任何的疼痛感,對孩子來說就像每天刷牙一樣輕松。如果孩子配合,窩溝封閉整個過程只需要20~第30分鍾。
