Summary

This study tested a new fluoride product to see if it can help remineralize white spot lesions—early signs of tooth decay. Twenty-three people with at least two active spots on their front teeth or premolars received both the experimental treatment and a standard fluoride varnish on different teeth. Researchers measured changes in mineral content using a special fluorescence camera to compare effectiveness.
