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 varnish applied before 4 years of age may leads to higher fluorosis (percentage prevalence in permanent teeth) compared with no fluoride varnish application (low certainty).
