牙齦深處是細菌最容易進入血管(全身循環系統)的部位,牙齦發炎的人都可以看到那一區是深紅色、脆弱、容易流血的,因此細菌也可以經由此處入侵身體,造成菌血症(血液中有細菌),繼而感染免疫力較低的老人或小孩之心臟、肺臟等等。
因此我叫病人一定要用牙線,清理到牙齦深處。
這裡卻反向思考:如何讓疫苗更容易進入身體,也是藉由這個細菌最容易進入身體的地方。
The deep part of the gums is the easiest place for bacteria to enter the bloodstream (systemic circulatory system). The inflamed gums area is dark red, fragile, and prone to bleeding. Therefore, bacteria can also invade the body through this area, causing bacteremia (bacteria in the blood), and infecting the heart, lungs, etc., of the elderly or children with weakened immune systems.
Therefore, I tell patients to use dental floss to clean deep into the gums.
Here, however, we think in reverse: how to make vaccines easier to enter the body, which is also through the place where bacteria can most easily enter the body.
