Which term describes the function of adhesive interfaces in dental restorations?

• A. Bonds
• B. Retention
• C. Wetting
• D. Tarnish

Answer: (A)

The function of adhesive interfaces in dental restorations is to create bonds between the tooth structure and the restoration, forming a strong, sealed connection that helps resist dislodgement and microleakage under function. This bonding results from the adhesive’s ability to wet and penetrate the tooth surface and to form chemical or micromechanical links with enamel, dentin, and the restorative material. Retention is about keeping the restoration in place, often through mechanical fit or design, which is related but not the same as the actual adhesive bonding at the interface. Wetting describes how well the adhesive spreads on and covers the surface, which is crucial for achieving a good bond but is a property of the bonding process rather than the function itself. Tarnish is a surface alteration from corrosion and has no role in the adhesive connection.
