    Researchers created a high-resolution map of human gum tissue to study smoking's effects on periodontitis.

  • 2

    Smoking weakens the gum's epithelial barrier, leading to structural and functional damage.

  • 3

    Fibroblasts in smokers show increased activity in genes related to aging, cell death, and wound repair.

  • 4

    Smoking-related periodontitis has more immune cells, particularly proinflammatory macrophages.

  • 5

    CXCL12 is identified as a potential therapeutic target to mitigate smoking-related periodontitis.
