Based on clinical populations, chronic orofacial pain of temporomandib
ular disorders (TMD) occurs more frequently (range: 2:1 to 9:1) in wom
en than men. The reasons for this difference are not clear. The presen
t study evaluated symptom presentation, sensitivity to pain, personali
ty, and illness behavior in 2 samples of patients suffering with orofa
cial pain. Also, pain responses were studied in pain-free volunteers,
controlling for experimenter-gender effects. The results showed few ge
nder differences based on ratings of chronic or experimental pain, pai
n-related illness behavior, and personality. The higher ratio of women
versus men seeking TMD care is consistent with greater health awarene
ss or interest in symptoms by women than by men.
