Area of Science:

  • Materials Science
  • Biomaterials Engineering

Context:

  • Dental cements are crucial in restorative dentistry.
  • Thermal insulation is a key property for patient comfort and pulp protection.

Purpose:

  • To measure and compare the thermal diffusivity of three common dental cements: Zinc Oxide Eugenol (ZOE), glass-ionomers, and poly-carboxylates.
  • To evaluate the thermal insulative efficiency of these dental materials.

Summary:

  • Thermal diffusivity was measured using thermocouples and a cooling bath apparatus, analyzed via a mathematical model.
  • Measured values ranged from 2,985 to 3,934 cm²/sec.
  • ZOE cement showed the highest thermal diffusivity, glass-ionomers the lowest, and poly-carboxylates were intermediate. Differences were not statistically significant.

Impact:

  • Dental cements exhibit thermal diffusivity similar to dentin.
  • These findings suggest that dental cements can be considered effective thermal insulators, potentially reducing thermal sensitivity during dental procedures.
