What is the disadvantage of using composites as restorative material ?

Correct answer: B. Decreased wear resistance

  • A. Increased thermal conductivity
  • B. Decreased wear resistance
  • C. Decreased thermal conductivity
  • D. None of the above

Explanation

Composites generally have lower wear resistance than amalgam, particularly in high-stress or posterior applications. Their low thermal conductivity is an advantage because it reduces thermal irritation to the pulp.
