Dental plaster casts should be stored in which color container?

• A. Blue container
• B. Black container
• C. Red container
• D. White container

Answer: (D)

Keeping plaster casts clean and easy to inspect is essential because they are porous and can absorb moisture, stains, or contaminants. A white container provides a light, neutral background that makes any dirt, moisture, or structural defects stand out clearly, so you can verify the cast’s condition at a glance. It also aids quick visual checks for cracks or deformations and helps ensure the casts remain dry and hygienic during storage. While other colors might be used for different materials or lab organization, white is favored for plaster casts because it supports visibility, cleanliness, and condition checks.
