Summary

This study looked at how smoking changes saliva and whether it makes teeth more prone to erosion. Fifty healthy volunteers wore a small device in their mouth to collect saliva samples. Researchers then measured how much calcium was lost from tooth samples and analyzed the saliva's makeup. The goal was to understand if smokers have a higher risk of dental erosion due to changes in their saliva.
