What is a common practice to ensure even distribution of light body impression material?

Extrude material from a distance
Use a spatula to spread
Keep the tip submerged in the material
Applying pressure to the tray

The correct answer is: Keep the tip submerged in the material

Keeping the tip submerged in the material is a common practice to ensure even distribution of light body impression material. When the tip is submerged, it allows for a consistent flow of the material, which helps prevent air bubbles from being trapped and ensures that the material will evenly coat the surfaces of the prepared area. This method promotes a more accurate impression by allowing for smooth and controlled application, ultimately leading to better detail reproduction in the final impression. The other methods can lead to variations in the distribution of the material; for instance, extruding material from a distance can cause it to lose its consistency and may result in uneven application. Using a spatula to spread the material could also introduce air and create uneven layers, while applying pressure to the tray might not facilitate the even distribution of the light body material, as it could push the material away from the desired areas rather than distributing it uniformly.
