Summary

This study tested two treatments to prevent enamel breakdown in children aged 6-13 with a condition called molar-incisor hypomineralization (MIH), which causes weak, chalky spots on teeth. 17 children received either a resin coating or a fluoride varnish on their affected molars. Researchers checked for new enamel damage over 6 months to see which treatment worked better.
