Effect of Caps Warmer and VisCalor Dispenser preheating on the color stability and surface roughness of resin composites after coffee immersion: an in vitro study

Using preheating devices may increase color changes in resin composites, particularly after prolonged immersion in a staining medium like coffee. Selecting an appropriate preheating method for timing and usability may be crucial for maintaining color stability. This study underscores the importance of considering both material choice and preheating technique in clinical applications to minimize discoloration risk.
