Fluoride toothpaste less than 1000 ppm (lower concentration) vs Fluoride toothpaste 1000 ppm or more (higher concentration)

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years

It is very uncertain whether fluoride toothpaste less than 1000 ppm (lower concentration) changes fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1000 ppm or more (higher concentration) (very low certainty).
