NCT ID NCT04807465
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether smoking changes how well a universal dental adhesive works when repairing tooth cavities near the gum line. Researchers tested three different ways of applying the adhesive in 47 adults who smoke at least 10 cigarettes a day. The goal is to see if smoking affects how long the filling lasts, its color, and sensitivity.
