title: The perception of induced dental pain in young and elderly women.
abstract: Pain threshold for electrical stimulation of healthy, unfilled teeth was studied in young and elderly women. Using the methodology of Sensory Decision Theory, ability to discriminate between suprathreshold shocks (d') and response bias were also assessed. No difference in threshold was observed betweeen the young and elderly groups. The elderly women were poorer at discriminating between suprathreshold shocks than the young women. These results were interpreted to reflect the integrity of highthreshold dental pulp afferents in the elderly and a central nervous system deficit on the part of the elderly for discriminating between such shocks. Significant age differences in response bias were also observed. Elderly subjects were biased against reporting shock as very faint pain compared to the young subjects and they restricted the range of their criteria across the six-point rating scale.
