ReviewThe effectiveness of cannabinoids in the management of chronic nonmalignant neuropathic pain: a systematic review.
To carry out a systematic review to assess the effectiveness of cannabis extracts and cannabinoids in the management of chronic nonmalignant neuropathic pain. ⋯ Cannabis-based medicinal extracts used in different populations of chronic nonmalignant neuropathic pain patients may provide effective analgesia in conditions that are refractory to other treatments. Further high-quality studies are needed to assess the impact of the duration of the treatment as well as the best form of drug delivery.

Randomized Controlled Trial Comparative StudyHeadache Attributed to Masticatory Myofascial Pain: Clinical Features and Management Outcomes.
To describe the characteristics of headaches attributed to temporomandibular disorders (TMD) and assess the effects of two management strategies used for the management of TMD on headache intensity and frequency. ⋯ Headache attributed to masticatory myofascial pain was mainly characterized by long duration, frontotemporal bilateral location, and a pressing/tightening quality. Also, counseling and behavioral management of masticatory myofascial pain improved headache, regardless of the use of an occlusal appliance.

Randomized Controlled Trial Comparative StudyShort-Term Sensorimotor Effects of Experimental Occlusal Interferences on the Wake-Time Masseter Muscle Activity of Females with Masticatory Muscle Pain.
To investigate the effects of the application of an acute alteration of the occlusion (ie, interference) on the habitual masseter electromyographic (EMG) activity of females with temporomandibular disorders (TMD)-related muscular pain during wakefulness. ⋯ An active occlusal interference in female volunteers with masticatory muscle pain had little influence on the masseter EMG activity pattern during wakefulness and did not affect the pressure tenderness of the masseter and temporalis.

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.
