Summary

This study looks at how metal and ceramic braces change the bacteria in dental plaque (biofilm) and affect gum health in 80 people with crooked teeth. Researchers will measure the types and amounts of bacteria, plaque buildup, and gum swelling. The goal is to understand how different braces influence oral infections and how well standard cleaning methods work.
