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 diffe…

This study looks at children aged 10-15 who need braces for prominent upper front teeth. Some will have upper premolars removed as part of treatment, others will not. Researchers will use sleep studies before and after treatment to see if the extractions increase the risk of obst…
