This study measured tooth surface temperatures during pulp vitality tests. Frigen spray caused rapid cooling, while CO2 snow reached -52°C, with a latex fingerstall moderating temperature changes.

Area of Science:

  • Dental research
  • Thermophysiology
  • Biomaterials science

Context:

  • Pulp vitality testing is crucial for diagnosing tooth health.
  • Accurate temperature measurement is essential for reliable vitality tests.
  • Frigen and carbon dioxide snow are commonly used cooling agents.

Purpose:

  • To record and analyze tooth surface temperatures during pulp vitality testing.
  • To compare the thermal effects of frigen spray and carbon dioxide snow.
  • To evaluate methods for controlling temperature changes during these tests.

Summary:

  • An in vitro study recorded human tooth surface temperatures during pulp vitality tests using frigen and carbon dioxide snow.
  • Frigen spray induced rapid temperature fluctuations.

  • Carbon dioxide snow achieved the lowest temperature (-52°C) at a pressure of 9.81 N, but a latex fingerstall effectively moderated temperature for higher readings and slower changes.

    • Impact:

    • Provides critical data on the thermal behavior of common pulp vitality testing agents.
    • Informs optimal techniques for conducting in vitro pulp vitality tests.
    • Suggests practical methods to enhance the safety and accuracy of dental temperature assessments.
