What is the influence of oral health literacy on the parents' choice of fluoride toothpaste?

Parents or guardians with higher OHL used less, and consequently more ideal amounts of, fluoride toothpaste for children compared to those with a lower level of OHL. This was the case both before and after the educational interventions. The allocation to intervention group did not predict the amount of toothpaste used. Finally, only schooling predicted the choice of correct fluoride toothpaste.
