Summary

This study tested whether a vitamin D mouthwash can help repair weak spots on children's permanent teeth (a condition called molar incisor hypomineralization) and improve gum health. Thirty-two children over age 6 used either a vitamin D or placebo mouthwash. Researchers measured tooth strength, plaque buildup, and gum bleeding to see if vitamin D made a difference.
