What is the primary benefit of using an etch-primer on enamel?

Enhanced aesthetics
Strongest bond
Reduced treatment time
Better color matching

The correct answer is: Strongest bond

Using an etch-primer on enamel primarily enhances the bond between the orthodontic materials and the tooth surface. The etching process creates micro-roughness on the enamel, which increases the surface area for adhesive bonding. This stronger mechanical interlocking significantly improves the bond strength, making it less likely for brackets or other appliances to debond during treatment. While aesthetics, treatment time, and color matching are relevant considerations in orthodontics, the main purpose of etching enamel with an etch-primer is to ensure a strong and durable bond. This strong bond is essential for the effectiveness of orthodontic treatment, as it helps maintain the position of brackets and other appliances throughout the duration of the treatment.
