牙周炎成因有哪些方面?

Posted By vickong pun     March 21, 2021

牙周炎首要體現為齒齦紅腫、出血,唔僅係刷牙時出血,有時係措辭或者咬硬物時也要出血,齒齦色彩暗紅,因為浮腫顯患上比力光亮此外,另有牙周袋形成,牙周炎是侵犯牙齦同牙周組織嘅慢性炎癥,是一種破壞性疾病,那麼,牙周炎成因有哪些方面呢?

菌斑

粘附於牙齒表面嘅微生物群,一般嘅潔牙同啷口水沖洗,唔能完全清除。

牙結石

牙結石是指沉積係牙面上嘅礦化嘅菌斑,根據其沉積部位同性質分為齦上牙結石同齦下牙結石兩種。

(1)齦上牙結石

位於齦緣以上嘅牙面上,肉眼可直接看到。係牙頸部沉積較多,特別是係大涎腺導管開口相對處,如上頜磨牙嘅頰側同下頜前牙嘅舌側沉積更多。齦上牙石中無機鹽嘅主要來源是唾液中嘅鈣、磷等礦物鹽。

(2)齦下牙結石

位於齦緣以下、齦袋或牙周袋內嘅根面上,肉眼唔能直視,必須去醫院檢查,方能知其沉積部位同沉積量。齦下牙石中無機鹽嘅主要來源是齦溝液。牙石對牙周組織嘅危害,主要是構成瞭菌斑附著同細菌滋生嘅良好環境。

牙周炎成因

創傷性咬合

係咬合時,若咬合力過大或方向異常,超越瞭牙周組織所能承受嘅合力,致使牙周組織發生損傷嘅咬合,稱為創傷性咬合。創傷性咬合包括咬合時嘅早接觸、牙合幹擾、夜間磨牙等。

以上就係牙周炎成因嘅具體介紹,牙醫建議,如果發現有牙周炎症狀,應馬上到口腔科就診。
