吸煙與牙周病?

  

  吸煙與牙周病?吸煙與牙周炎的流行分佈密切相關,主要通過局部和全身因素影響牙周炎的發生和發展。

局部因素:吸煙者的口腔衛生差,菌斑蓄積,牙石、軟垢增多,既是牙齦炎,也是牙周炎的主要致病因素。
吸煙使口腔內缺氧,口腔內ph值發生改變,有利於厭氧菌的生存。

全身因素:吸煙可引起機體免疫功能改變。

吸煙者口腔局部免疫功能低下,調查發現吸煙者唾液中iga水準低於不吸煙者。
其他方面:有報導煙草中尼古丁進入血液,導致牙齦血管收縮,血流減少,以致牙齦氧供和血氣交換減少。
清除廢物能力降低,導致牙齦保護性修復功能降低。

研究證明:尼古丁通過刺激成骨細胞鹼性磷酸酶的活性,抑制細胞增殖,促進牙槽骨吸收。
