Comparative Study
Peripheral painful traumatic trigeminal neuropathy: clinical features in 91 cases and proposal of novel diagnostic criteria.
To field-test carefully designed criteria for pain following trigeminal nerve trauma. ⋯ Overall, the proposed PPTTN criteria have proven to be clinically useful. In view of these results, modified PPTTN diagnostic criteria are proposed for use in future research.

Comparative Study
Biopsychosocial factors associated with the subcategories of acute temporomandibular joint disorders.
To assess the biopsychosocial factors associated with acute temporomandibular disorders (TMD) based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). ⋯ Participants with multiple diagnoses reported higher pain, as well as other symptoms, relative to participants without a TMD diagnosis. For chewing performance, participants with mutual diagnoses reported more pain compared to other participants. Finally, the risk-status of patients significantly affected chewing performance.

To study the effect of radiofrequency thermocoagulation (RFT) of the sphenopalatine ganglion (SPG) on headache and facial pain conditions following critical reevaluation of the original diagnosis. ⋯ Correct headache and facial pain diagnosis is vital to assess the outcome of different treatment strategies. Even in a tertiary center, headache and facial pain can be misdiagnosed. RFT of the SPG may be effective in patients with facial pain, but repeated procedures are often needed.

To investigate the influence of noxious stimulation of the temporomandibular joint (TMJ) on conditioned pain modulation (CPM) and the possible influence of gender on such CPM effects in the craniofacial region of humans. ⋯ Acute noxious stimulation of the TMJ does not alter the magnitude of CPM effects on masseter muscle pain in either gender. It is suggested that deficiencies in CPM in persistent pain conditions are most likely more related to the duration of clinical pain than the pain per se.

Comparative Study
Comparison of techniques for evaluation of deep pain sensitivity in the craniofacial region.
To determine whether a new palpometer and manual palpation can detect site-to-site differences in human craniofacial pain sensitivity in a similar pattern to that of an electronic pressure algometer and subsequently to compare between-session and within-session variability of palpometer and manual palpation. ⋯ The palpometer and manual palpation could detect differences in craniofacial sensitivity in healthy subjects, with no significant differences between repeated sessions. All techniques showed the highest sensitivity at the retromandibular site and the lowest at the temporalis muscle site. The palpometer had lower within-session variability compared with manual palpation.
