Dental plaster and dental stone are both types of gypsum products used in dentistry, but they differ in their properties and applications. Here's a simple breakdown:

Dental Plaster:

Composition: Made by heating gypsum(calcium sulfate dihydrate) at a specific temperature, which partially dehydrates the material, creating a powder.

Properties: It is softer, more porous, and less dense than dental stone.

Setting time: Faster setting time compared to dental stone.

Strength: Weaker than dental stone, not suitable for detailed or high-strength applications.

Uses: Primarily used for preliminary models, or for making impressions where strength is not a critical factor.

Dental Stone:

Composition: Dental stone is made by heating gypsum to a higher temperature, resulting in a denser and stronger material.

Properties: It is denser, less porous, and stronger than dental plaster. It also has better dimensional stability.

Setting time: Slower setting time than dental plaster.

Strength: Stronger and more durable than dental plaster, which makes it ideal for making final models, casts, or when detailed work is needed.

Uses: Used for creating detailed dental models, crowns, bridges, dentures, and other restorations.

5. Type V – High-Strength, High-Expansion Dental Stone

# data[].attributes.body
Dental plaster and dental stone are both gypsum-based materials used in dentistry, but they have different properties and applications. Here are the key differences:

1. Composition & Particle Size:

Dental Plaster (Type II): Made of beta-hemihydrate (CaSO₄·½H₂O), with irregular and porous particles, making it weaker and more porous.

Dental Stone (Type III, IV, and V): Made of alpha-hemihydrate, with more uniform, denser, and less porous particles, resulting in higher strength and lower water absorption.

2. Strength & Hardness:

Dental Plaster: Weaker and softer due to larger, porous particles.

Dental Stone: Much stronger and more durable, especially Type IV and V, which have very high compressive strength.

3. Water-Powder Ratio:

Dental Plaster: Requires more water to form a workable mix (higher water-powder ratio).

Dental Stone: Requires less water (lower water-powder ratio), leading to a denser and stronger final product.

4. Uses in Dentistry:

Dental Plaster: Used for preliminary models, diagnostic casts, and mounting casts on articulators because of its easy trimming and lower cost.

Dental Stone: Used for working models, study models, and fabricating dentures, crowns, and orthodontic appliances due to its higher precision and durability.

5. Setting Expansion:

Dental Plaster: Higher setting expansion (~0.2-0.3%), leading to less accuracy.

Dental Stone: Lower setting expansion (~0.08-0.1%), providing more precise models.

# data[].attributes.body
Dental plaster and dental stone are both gypsum-based materials used in dentistry, but they differ in composition, properties, and applications.

1. Composition & Processing:

Dental Plaster (Type II): Made by heating gypsum at a lower temperature (about 110-120°C) under atmospheric pressure, producing irregular, porous particles.

Dental Stone (Types III, IV, and V): Heated under steam pressure or in an autoclave at a higher temperature, resulting in denser, mo
