Comparative Study
Orofacial pain conditions and impact on quality of life in community-dwelling elderly people in Hong Kong.
To determine orofacial pain (OFP) characteristics, associated disability, and effect on quality of life in elderly community-dwelling Chinese people. ⋯ OFP had a substantial detrimental impact on daily life activities, psychological distress level, and quality of life in Chinese elders. MST and DA conditions had the greatest adverse impact on quality of life.

To evaluate the sensitivity and reproducibility of a multimodal psychophysical technique for the assessment of both spatial and temporal changes in somatosensory function after an infraorbital nerve block. ⋯ The present findings indicate that the psychophysical method is sufficiently reproducible, with no major differences between sessions in healthy subjects. All stimulus modalities demonstrated adequate sensitivity. Furthermore, measurement of points in 5 x 5 matrices allowed a spatial description of somatosensory sensitivity. This method may be valuable for studies on changes in somatosensory sensitivity following trauma or orthognathic surgery on the maxilla.

To test in vitro and in vivo the reliability and accuracy of a new algometer, the pressure algometer for palpation (PAP), for measuring pressure pain thresholds (PPTs) and to compare its features with those of a commercially available pressure algometer. ⋯ Both the PAP and the Somedic algometer showed high reliability. Concurrent validity was demonstrated by statistically significant correlations between the devices. Both showed equally high capacity for differentiating TMD cases from controls. The PAP yielded significantly higher PPTs than the Somedic algometer.

To develop and validate a questionnaire-based tool which would enable classification of idiopathic orofacial pain in the general population. ⋯ The classification criteria developed for idiopathic orofacial pain can be used as a screening tool for subjects with this condition in the general population.

To examine differences in temporal summation of mechanically evoked pain between women and men suffering from chronic pain associated with temporomandibular disorders (TMD), as well as between male TMD patients and healthy controls. ⋯ These findings suggest that central nociceptive processing upregulation is likely to contribute to TMD pain for women but is not a factor for
