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.

Randomized Controlled Trial Comparative Study
Palmitoylethanolamide versus a nonsteroidal anti-inflammatory drug in the treatment of temporomandibular joint inflammatory pain.
To carry out a randomized clinical trial to compare the effect of palmitoylethanolamide (PEA) versus ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), for pain relief in temporomandibular joint (TMJ) osteoarthritis or arthralgia. PEA acts as an endogenous agent with an autacoid local inflammation antagonism and modulates mast cell behavior controlling both acute and chronic inflammation. ⋯ These data suggest that PEA is effective in treating TMJ inflammatory pain.

To evaluate the relationship between preoperative resting arterial blood pressure and postoperative pain in patients undergoing nonsurgical root canal therapy. ⋯ This study has provided further evidence of a functional interaction between the cardiovascular and trigeminal pain regulatory systems. Understanding this complex relationship may lead to enhanced pain management strategies.

To determine whether mucosal pain, evoked through a novel topical capsaicin model, has an effect on jaw movement and whether psychologic factors have an association with any pain-induced movement effects. ⋯ Capsaicin-induced mucosal pain resulted in a significant increase in chewing rate but had no effect on amplitude or velocity in opening/closing jaw movements and chewing. Anxiety and depression scores correlated negatively with velocity in free opening jaw movement and chewing rate, respectively.

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.
