點解會得牙齦炎、牙周炎?

牙齦炎、牙周炎指嘅系發生喺牙齒周圍組織嘅炎症性疾病,通俗嘅講就系「牙床」發炎了。牙齦炎主要系堆積喺牙面和牙齦溝嘅細菌、牙石引起嘅牙齦嘅炎症、出血和腫脹,如果炎症進一步發展引起牙槽骨嘅破壞,咁就發展成牙周炎了。呢組疾病喺人群中嘅發生率極高,幾乎所有人喺一生中都會有牙齦炎嘅發生,成年人中很多人都有或輕或重嘅牙周炎症。咁點解會得牙齦炎、牙周炎呢?

點解會得牙齦炎、牙周炎?

點解會得牙齦炎、牙周炎?

牙齦炎、牙周炎嘅罪魁禍首就系口腔裏嘅牙周致病菌。我哋嘅口腔與外界相通,系一個有菌嘅環境,大量嘅細菌以生物膜嘅方式粘附喺牙齒嘅表面,我哋稱之為菌斑。牙菌斑中有一部分細菌系有致病性嘅,隨著菌斑堆積嘅時間延長,致病菌嘅比例就會升高。

堆積嘅菌斑會喺唾液環境中鈣化變硬,形成牙結石,牙結石表面粗糙,又會吸附大量菌斑。因此菌斑、牙石中大量嘅致病菌引起了牙齦炎症,當呢些致病菌直接或間接地破壞牙周附著組織和牙槽骨時,牙周炎就發生了。牙周炎嘅程度與菌斑有關,也與患者嘅抵抗力有關,有些重度嘅牙周炎還可能有遺傳背景。

牙菌斑系引起菌斑性齦炎嘅直接病因,通過潔治術清除菌斑、牙石後,牙齦炎症可喺一周左右消退,牙齦完全恢復正常。牙周炎患者喺經過恰當嘅治療後,炎症消退,病情唔會進一步發展,但牙周組織嘅破壞很難完全恢復,必要時需要進行牙周手術治療,達到促進組織再生嘅目的。

以上就系「點解會得牙齦炎、牙周炎?」嘅具體介紹,希望對大家有所幫助。
