Assessment of operator-associated variability in thermal pulp sensibility tests: A simulation study using a...

Area of Science:

• Dentistry
• Dental Diagnostics
• Pulp Vitality Assessment

Background:

• Thermal pulp sensibility tests are essential for evaluating pulp vitality and prognosis.
• Current methods suffer from subjective patient responses and operator variability, affecting accuracy.
• Operator variability in performing heat and cold pulp tests was investigated using a custom apparatus.

Purpose of the Study:

• To evaluate operator-associated variability in thermal pulp sensibility testing.
• To assess the performance of heat and cold pulp tests under controlled conditions.
• To identify potential risks and limitations associated with current thermal testing protocols.

Main Methods:

• A cross-sectional study involving 23 dentists performing heat and cold tests on a custom apparatus.
• Recording of thermal and temporal parameters, including tool heating/cooling time and temperature on tooth.
• Measurement of tool temperature, maximum tooth temperature, and maximum tool temperature.

Main Results:

• Heat testing instruments exceeded 400°C, with application durations often surpassing 10 seconds, posing a burn risk.
• Cold testing with Endo-Frost spray failed to reach sufficiently low temperatures (-50°C) for effective pulpal stimulation.
• Significant temperature loss during cold tests compromised efficacy, indicating substantial operator-induced variability.

Conclusions:

• Considerable operator-induced variability exists in thermal pulp sensibility testing.
• Findings suggest potential implications for diagnostic accuracy and patient safety.
• Standardized protocols are necessary to reduce operator-related discrepancies and enhance diagnostic reliability.
