Changes in pulp temperature during thermostimulation of human teeth by a simple electrically controlled thermode

Area of Science:

• Biomedical Engineering
• Sensory Science
• Dental Research

Background:

• Accurate measurement of tooth temperature is crucial for understanding thermoperception.
• Existing methods may not fully replicate the thermal environment of the oral cavity.
• Electrically controlled devices offer precise temperature regulation.

Purpose of the Study:

• To describe a novel, electrically controlled thermode for psychophysical experiments.
• To investigate human thermoperception in teeth.
• To measure intrapulpal temperature dynamics during thermal stimulation.

Main Methods:

• Development of a simple, electrically controlled thermode.
• Conducting psychophysical experiments on human subjects.
• In vitro measurement of intrapulpal temperature changes during controlled heating/cooling (60s).
• Stimulation of temperature exchange between the tooth and surrounding simulated tissues.

Main Results:

• The described thermode allows for controlled thermal stimulation of teeth.
• Intrapulpal temperature changes were successfully measured during cooling and heating.
• In vitro experiments simulated the thermal exchange present in vivo.

Conclusions:

• The developed thermode is a viable tool for studying tooth thermoperception.
• This method allows for precise investigation of temperature perception in human teeth.
• Further research can utilize this device to explore various aspects of dental sensory function.
