Which term refers to dental stone and plaster when mixed with water and set into an irreversible solid mass?

• A. Impression Materials
• B. Replacement Denture
• C. Gypsums
• D. 5-7 years

Answer: (C)

Gypsum materials. Plaster and dental stone are both gypsum-based dental materials. When these powders are mixed with water, a chemical reaction occurs that rehydrates the hemihydrate back to calcium sulfate dihydrate, forming a hard, rigid mass that cannot be reversed. This set forms the casts and dies used in prosthodontics and restorative procedures. The term you’re looking for is gypsum products (often referred to as gypsums).
