What is the term for the foundation that binds a substance together, with continuous polymeric phases in which filler particles are dispersed in composite resin?

• A. Irregular
• B. Malleability
• C. Matrix
• D. Percolation

Answer: (C)

The term describes the continuous polymeric phase that holds everything together in a composite resin. This matrix forms the surrounding network that binds the dispersed filler particles, giving cohesion and the ability to transfer stress through the material. By surrounding the fillers, the matrix defines the overall structure and properties of the composite, such as durability and esthetics, while the fillers enhance strength and wear resistance. Other terms don’t fit because they don’t capture this binding role. Irregular refers to a shape or pattern, not a binding medium. Malleability describes how easily a material can deform, not the binding phase. Percolation is about connectivity in a network, not the continuous resin that holds the composite together.
