You May Get Future Vaccines via Dental Floss
Researchers have demonstrated a novel vaccine delivery method, using dental floss to introduce vaccine via the tissue between the teeth and gums.
“We found that approximately 60% of the dye was deposited in the gum pocket, which suggests that floss picks may be a practical vaccine delivery method to the epithelial junction,” Ingrole says. The study was supported in part by the National Institutes of Health (NIH) under grants R01AI137846 and R01DE033759, and by funds from the Whitacre Endowed Chair in Science and Engineering at Texas Tech University. Here we show that flat tape dental floss can deliver vaccines through the junctional epithelium of the gingival sulcus, exploiting its naturally leaky properties.
