老年人患牙周病嘅原因系乜?

老年人患牙周病嘅原因系乜?牙周炎系系最常見嘅口腔疾病之一,發作喺牙齒支持組織(牙齦、牙周膜、牙槽骨)嘅一種慢性、毀壞性疾病。老年人也會經常發生牙周炎咁嘅牙齒症狀,咁,老年人患牙周病嘅原因系乜呢?老年人患牙周炎嘅原因有以下幾個方面:1、牙結石

老年人患牙周病嘅原因系乜?牙結石系沉積喺牙面上礦化嘅菌斑。牙石根據其沉積部位和性質分為齦上牙石和齦下牙石兩種:齦上牙石位於齦緣以上嘅牙面上,肉眼可直接睇到。喺牙頸部沉積較多,特咪喺涎腺導管開口相對處,如上頜磨牙嘅頰側和下頜前牙嘅脷側沉積更多。
齦上牙石中無機鹽嘅主要來源系唾液中嘅鈣、磷等礦物鹽。齦下牙石位於齦緣以下、齦袋或牙周袋內嘅根面上,肉眼唔得直視,必須用探針探查,方能知其沉積部位和沉積量。齦下牙石喺任何牙上都可形成,但以牙嘅鄰面和脷面較多。齦下牙石主要系齦溝液和滲出物內嘅礦物鹽鈣化而成。2、創傷性咬合喺咬合時,若咬合力過大或方向異常,超越了牙周組織所能承受嘅咬合力量,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、干擾、夜間磨牙等。
3、全身性因素全身性因素包括:年齡、性別、遺傳、內分泌、營養、糖尿病等因素使牙齒嘅支持組織逐漸被破壞,失去了支撐嘅牙齒最後松動、咀噍無力,梗系唔得發揮咀噍功能了。
