Physical properties of dental materials
Dental materials possess various physical properties that are crucial for their clinical performance. These properties include: 1. ** Density **: The mass of a material per unit volume. 2. ** Hardness **: The resistance of a material to indentation or scratching. 3. ** Elasticity **: The ability of a material to return to its original shape after deformation. 4. ** Flexibility **: How easily a material can be bent or flexed without breaking. 5. ** Compressive Strength** : The maximum compressive load a material can withstand without breaking. 6. ** Tensile Strength* *: The maximum tensile load a material can withstand without breaking. 7. ** Fracture Toughness **: The ability of a material to resist crack propagation. 8. ** Coefficient of Thermal Expansion **: The change in volume or length of a material with a change in temperature. 9. ** Thermal Conductivity* *: The ability of a material to conduct heat. 10. ** Electrical Conductivity **: The ability of a material to co
