Thermosensation

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Summary

This summary is machine-generated.

Thermography revealed a temporary increase in skin temperature on the operated side after mandibular third molar surgery. This method aids in assessing inflammation but cannot measure absolute temperature changes over time.

Background:

Mandibular third molar surgery can lead to post-operative inflammation.
Accurate assessment of inflammation is crucial for patient recovery.
Thermography offers a non-invasive method for monitoring surface temperature changes.

Purpose of the Study:

To evaluate differences in facial skin temperature between operated and control sides post-mandibular third molar extraction.
To assess the utility of thermography in quantifying post-surgical inflammation.

Main Methods:

127 patients underwent mandibular third molar removal.
Facial thermograms were captured pre-operatively, 2 days, and 7 days post-surgery.
Paired t-tests analyzed temperature differences in the third molar region.

Main Results:

A significant temperature increase (0.33°C) was observed on the operated side 2 days post-surgery (p < 0.001).
No significant temperature differences were found between sides pre-operatively or at 7 days post-surgery.
The control side showed a significant temperature decrease at 2 days post-surgery compared to pre-operative levels (p < 0.001).

Conclusions:

Thermography is a valuable tool for quantitatively assessing localized inflammation after mandibular third molar surgery.
The study highlights thermography's potential for comparing intervention and control sides.
Absolute temperature changes over time are difficult to ascertain due to natural skin temperature variations.
