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
Fluoride toothpaste 550 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1000 ppm (higher concentration) (moderate certainty).
