Randomized Controlled Trial Comparative StudyIntramuscular temperature modulates glutamate-evoked masseter muscle pain intensity in humans.
To determine whether glutamate-evoked jaw muscle pain is altered by the temperature of the solution injected. ⋯ Glutamate-evoked jaw muscle pain was significantly altered by the temperature of the injection solution. Although temperature perception in the jaw muscle is poor, pain intensity is increased when the muscle tissue temperature is elevated.

Randomized Controlled Trial Comparative StudyPreoperative Local Administration of Morphine as an Add-on Therapy in Patients Undergoing Surgical Removal of an Odontogenic Maxillary Cyst. A Randomized, Double-Blind Pilot Study.
To evaluate whether a combination of locally administered morphine (1 mg) and lidocaine as part of a multimodal analgesic approach is safe, and whether it improves pain control during the first 24 hours after odontogenic maxillary cyst removal under general anesthesia compared to local lidocaine alone. ⋯ Within the limitations of this study, local administration of 1 mg of morphine prior to the surgical removal of an odontogenic maxillary cyst was safe, but it did not prove to be very effective as an add-on therapy for postoperative pain control.

Randomized Controlled Trial Comparative StudyCan experimentally evoked pain in the jaw muscles or temporomandibular joint affect anterior bite force in humans?
To test the hypothesis that experimental pain in the masseter muscle or temporomandibular joint (TMJ) will decrease the anterior maximum voluntary bite force (MVBF) and jaw muscle activity in relation to the perceived effort. ⋯ Experimental pain from either masseter muscle or TMJ did not affect the MVBF, in accordance with the subject-based reports. Jaw muscle activity, except for EMG activity of the anterior temporalis and anterior digastric muscles during TMJ pain, also remained unaffected by pain. The findings suggest that it is not pain in itself but rather how pain is perceived that may lead to adaptation of motor function, supporting an integrated pain adaptation model.

Comparative Study Clinical TrialMyofascial pain: an open study on the pharmacotherapeutic response to stepped treatment with tricyclic antidepressants and gabapentin.
To evaluate, in an open trial, the pharmacotherapeutic efficacy of tricyclic antidepressant (TCA) drugs and gabapentin in patients with persistent myofascial pain and to identify patient and pain characteristics that may predict treatment outcome. ⋯ This study has demonstrated the good pharmacotherapeutic response of persistent myofascial pain, even in more severe cases. Not being a randomized controlled trial, the results may be biased and should be interpreted with caution. Patients who do not respond to TCAs may be a distinct subgroup and this needs further investigation. The results also suggest that gabapentin, at a lower dose than previously reported, is a good alternative in TCA-resistant patients.
