近 1600 萬美國人患有呼吸系統疾病慢性阻塞性肺疾病 (COPD),使其成為美國第六大死因。但本月《牙周病學雜誌》上描述的一項新研究結果表明,僅僅更好地呵護牙齦可能有助於 COPD 患者阻止疾病的進展。

來自布法羅大學的口腔生物學家研究了 13,792 名患者的牙齦和肺部。他們發現,患有牙周病的人患 COPD 的風險比牙齦健康的人高出 1.5 倍。此外,肺部問題隨著口腔健康狀況的下降而惡化。“我們知道 COPD 的發生和進展取決於吸菸,並且反覆的細菌感染會使肺部疾病惡化,”團隊成員弗蘭克·A·斯坎納皮科說。“牙周細菌有可能透過唾液或正常呼吸進入肺部,並在某種程度上促進肺部感染。另一種可能性是牙周病引起的炎症可能導致肺氣道內膜炎症,從而限制了進出肺部的空氣量。”

斯坎納皮科指出,雖然不刷牙不會導致肺部疾病,但“如果您已經患有肺部疾病,那麼呵護您的牙齒和牙齦就尤為重要。”

Kate Wong is an award-winning science writer and senior editor at 大眾科學 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
