Final answer:
The dental gypsum product that requires the least water for mixing and has the highest final density is dental stone, high strength (type IV).
Step-by-step explanation:
The dental gypsum product that requires the least water for mixing and has the highest final density is dental stone, high strength (type IV).
Dental gypsum products, such as impression plaster (type I), model plaster (type II), dental stone (type III), and dental stone, high strength (type IV), are used in dentistry for various applications, such as making models of teeth and jaws, pouring impressions, and producing casts for prosthetics.
The final density of a dental gypsum product depends on its water-to-powder ratio. Higher water-to-powder ratio results in lower final density. Dental stone, high strength (type IV), requires the least water for mixing and has the highest final density, making it suitable for producing accurate and strong dental casts.
