What is the least reliable vitality testing method?

Thermal testing
Laser Doppler flowmetry
EPT
Radiographs

The correct answer is: EPT

EPT (electric pulp testing) is the least reliable vitality testing method because it only measures the ability of a nerve to conduct electricity, rather than directly measuring the nerve's vitality. It can be affected by many factors such as moisture, temperature, and the thickness of dentin. This makes the results less accurate compared to thermal testing, which directly measures the nerve's response to temperature, or laser Doppler flowmetry, which measures blood flow in the pulp. Radiographs, while not a vitality testing method, can also provide information about the health of the pulp and surrounding structures and can help confirm initial test results.
