牙齦出血?可能系慢性牙齦炎!

牙齦出血有人覺得好正常,但又有人對牙齦出血很害怕,誤認為系得咗壞血病(維生素C缺乏)或系白血病嘅反應。的確,缺少維生素C、白血病以及其他全身性疾病,都有牙齦出血症狀,但都唔系牙齦出血嘅常見原因,最常見嘅原因,仲系慢性牙齦炎。

牙齦出血?好可能系慢性牙齦炎!

乜系慢性牙齦炎?

牙齦系一個嬌嫩嘅黐膜,有豐富嘅血管,邊緣緊貼喺牙齒頸部,形成了一條整齊嘅波浪形曲線,喺牙與牙齦之間有一條環狀嘅1~2 mm深嘅小溝(齦袋),牙與牙之間,又存在一條自然縫隙(牙縫),呢種牙縫喺牙列唔整齊嘅人中更易睇出。

由於食物和碎屑很容易嵌塞喺牙縫和齦袋內,唾液中嘅鈣鹽也就很容易沉積喺呢些地方形成斑塊,多種厭氧菌更以此為溫床而大肆繁殖。呢啲斑塊如果冇得到徹底清除,佢哋就會形成牙垢或牙石,並緊貼喺牙頸部嘅牙面上(特別系內側),甚至延伸至齦下。牙垢和牙石中嘅多種理化,生物不良刺激,結果導致牙齦慢性炎症,出現紅、腫、潰爛、出血等症狀。本病病程可持續多年。

牙齦炎只侵犯牙齦,唔侵犯其他牙周組織,所以牙齒唔發生鬆動,X線片檢查牙槽骨、牙周膜、牙骨質無異常。由於牙齦炎病因明確,牙菌斑系發病嘅致病因素,且病變只局限喺牙齦,因此,除去病因,消除菌斑,即可得到明顯效果。

以上就系「牙齦出血?好可能系慢性牙齦炎!」嘅具體介紹,希望對大家有所幫助。
