Brushed less than twice per day vs Brushed twice or more per day
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 brushed less than twice per day changes fluorosis (percentage prevalence in permanent teeth) compared with brushed twice or more per day (very low certainty).
