Formulations with desensitizing agents such as potassium nitrate and fluoride showed lower dropout rates in longer programs.
LED devices with milder peroxides proved suitable for users with crowns or veneers seeking conservative enhancement.
Product Ingredients And Stability
Stabilized hydrogen peroxide and carbamide peroxide formulations maintained higher active oxygen levels over shelf life.
Packaging that minimized air exposure, light blocking tubes, and unit-dose formats correlated with consistent performance.
