Somatosensory evoked response and jaw opening reflex elicited by tooth pulp stimulation in awake freely moving rats.
OBJECTIVE: Investigation of pain and nociception refers to different models. Depending upon the intensity of stimulation, unmyelinated pulpal fibers or periodontal A-fibers can be stimulated producing a short or a long latency jaw opening reflex of the digastric muscle.
