Purpose/Question
The authors aimed to answer 4 questions:
1.Is sensitivity to standardized noxious stimuli (perceived usually as painful) predictive of TMD risk?
2.What psychological characteristics are associated with pain sensitivity?
3.Are those same psychological characteristics predictive of TMD risk?
4.Is the magnitude of TMD risk associated with those psychological factors attenuated after adjustment for variants of the gene encoding COMT?
