Which component in composite resin material contributes to its hardness and wear resistance?

The resin matrix alone, such as the Bis-GMA monomer base
Inorganic filler particles such as silica dispersed in the resin
The residual water content within the set composite material
The bonding agent that is applied to the cavity walls before placement

Show answer and explanation

Correct answer: Inorganic filler particles such as silica dispersed in the resin

Composite resin’s strength and wear resistance come from inorganic filler particles dispersed in the resin matrix — they provide structural reinforcement and wear resistance.
