Summary

This study looks at how smoking cigarettes, e-cigarettes, or a water pipe (narghile) affects the gums and teeth of university students aged up to 25. Researchers will measure plaque, gum inflammation, pocket depth, and other signs of gum disease in 90 smokers. The goal is to see if one type of smoking is worse for oral health than the others.
