🔹 Composition and Health Impact of Oral Microbiome
【📌 Core Finding】The oral microbiome comprises roughly 700 bacterial species, alongside fungi and viruses, which profoundly influence systemic health. 【🔸 Causal Path】Poor oral hygiene creates oxygen-poor environments where harmful pathogens like Porphyromonas gingivalis thrive, causing gum disease and increasing the risk of cardiovascular disease, diabetes, Alzheimer's disease, and pancreatic cancer. 【⭐ Diversity Factor】Lower microbial diversity in the mouth is directly associated with depression and systemic inflammation.
