Fifty-five low back pain patients and 47 healthy volunteers judged the intensity of calibrated thermal stimuli. The method of constant stimuli yielded a pain threshold, and sensory decision theory (SDT) methods provided two independent indices of perceptual performance: discriminability, P(A), the ability to differentiate among various stimulus intensities;(More)
The purpose of this study was to determine whether pulpal responses to cold temperatures applied to enamel, using a method that precisely controls the intensity of the cold stimulus or measures the response time, could distinguish dentin-sensitive teeth from nonsensitive teeth. Eighteen human subjects were stimulated with cold temperatures decreasing in 5(More)
