兒童溝隙封填保健知識知多D

——兒童溝隙封填保健知識知多D  小朋友嘅乳牙一共有20顆, 「六歲齒」系指約六歲左右喺乳牙臼齒後新萌出嘅恆牙。很多家長並唔知果個系成人牙。新長出嚟嘅臼齒,牙齒嘅咬合面通常會凹凸不平,有許多很深嘅小窩溝及小裂溝(就系所謂嘅溝隙),呢些地方就算系大人都唔太容易徹底清潔干凈,更唔使講系小朋友,而一般蛀牙產生嘅位置,最早大多開始於臼齒嘅咬合面溝隙之中,縫隙深處易藏污納垢,所以很容易造成蛀牙。因此溝隙封填劑就系要把呢些細小嘅溝隙封填起嚟,把細菌和牙菌斑隔絕在外以預防齲齒嘅發生。
溝隙封填保健  溝隙封填劑 (Pit and Fissure Sealant)  溝隙封填劑系一種特咪設計嚟填平呢些溝隙嘅液態樹脂材料,具有良好嘅流動性,牙齒表面經過特定嘅處理過程可以和呢種材料緊密接合。臨床研究證實可以有效減少咬合面上嘅蛀牙,而對剛萌發嘅牙齒(尤其恆牙第一大臼齒)預防效果尤佳。  溝隙封填劑能維持多久?  研究顯示溝隙封填劑能維持好幾年,只要保持良好嘅口腔清潔習慣並避免咬太硬嘅食物, 溝隙封填劑可以維持更久,因此牙齒剛長出嚟最容易蛀牙嘅頭幾年,佢可以讓牙齒獲得最好嘅保護。一般而言,2至3歲乳臼齒長出後,就可以開始做溝隙封填,最好定期回診檢查,以防止周邊蛀蝕,造成溝隙封填劑脫落而前功盡棄。
