The ability of dental materials to withstand tensile forces is directly related to their strength. In the context of dental materials, tensile strength refers to the maximum amount of tensile (pulling) stress that a material can endure before failure occurs. This characteristic is crucial for various dental applications, including crowns, bridges, and other restorations, where materials are subject to pulling forces during normal function.

Strength encompasses both tensile strength and compressive strength, making it a vital property for ensuring that dental materials can not only withstand the daily stresses of biting and chewing but also maintain their integrity over time. Evaluating strength in dental materials ensures that they will hold up under the mechanical forces encountered in the oral environment, providing reliability and longevity for dental restorations.

While elasticity pertains to a material's ability to deform elastically and return to its original shape, and durability relates to the material's overall resilience over time against wear and degradation, these properties do not specifically address the material's ability to resist tensile forces. Viscosity, on the other hand, refers to a fluid's resistance to flow and is not relevant in this context as it applies to the behavior of liquids rather than solid materials subject to tensile stress.
