Explain the gate control theory of pain perception related to the use of pressure anesthesia for palatal injections
What will be an ideal response?
The gate control theory of pain perception suggests that there are neurological gates that can block signals to the brain. This theory asserts that the perception of physical pain is not based solely on the activation of nociception. The experience of pain is a modulation between activation of large non-pain-transmitting (non-nociceptive) nerve fibers and small pain-transmitting (nociceptive) nerve fibers; the activation of large non-nociceptive fibers can interfere with signals from small nociceptive fibers; and the stimulation of non-nociceptive fibers is greater than the stimulation of nociceptive fibers causing pain to be inhibited or blocked.
The stimuli of pressure anesthesia therefore blocks the pain stimuli caused by the penetration of the needle.
