Randomized Controlled TrialAdditional effect of occlusal splints on the improvement of psychological aspects in temporomandibular disorder subjects: A randomized controlled trial.
To measure the effect of occlusal splints as an additional treatment on psychological aspects in temporomandibular disorder patients. ⋯ Minimally invasive strategies could provide an improvement in the psychological aspects of temporomandibular disorder patients, and the use of an occlusal splint seems to hasten the manifestation of these effects.

Randomized Controlled Trial Comparative StudyComparison of platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and concentrated growth factor (CGF) in rabbit-skull defect healing.
The objective of this study was to evaluate the effect of platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and concentrated growth factor (CGF) on bone healing. ⋯ The addition of PRP, PRF, and CGF had significantly increased bone formation at the 6th week. The effect of PRP, PRF, and CGF was similar and may be useful in the future to increase the success rate of bone grafting.

Randomized Controlled Trial Comparative StudyInfluence of topical anaesthesia on the corticomotor response to tongue training.
The aim of this experimental study was to investigate if perturbation of somatosensory function would change corticomotor excitability of the tongue musculature in relation to a novel tongue training task. ⋯ Topical anaesthesia has no major effects on corticomotor excitability of tongue musculature and there appears to be a strong individual variation in the effects of a tongue training task on MEP amplitudes.

Randomized Controlled TrialEffect of experimental pain on EMG-activity in human jaw-closing muscles in different jaw positions.
We examined the effect of a standardized painful stimulus on the surface EMG-activity of the human jaw-closing muscles at rest and during two levels of jaw opening. Sixteen healthy women participated in two experimental sessions. In randomized order, hypertonic saline (HS: 5.8%) was infused into the left masseter muscle on one occasion, and isotonic saline (IS: 0.9%) on the other. The subjects scored the pain intensity continuously on a 0-10 visual analogue scale (VAS). The subjects were asked to hold the jaw in three different positions (rest, half-maximal, and maximal opening). Before, during, and after infusion, the EMG-activity was recorded from the masseter and temporalis muscles with the jaw in each of the three positions. HS induced significantly higher pain-levels than IS (mean VAS: HS: 5.2+/-1.3, IS: 0.7+/-0.2, P<0.05). At rest, the EMG-activity in most of the jaw muscles increased significantly during both infusions (P<0.05). At half-maximal opening, the EMG-activity in the infused muscle increased significantly with both HS and IS (P<0.05). At maximal opening, the EMG-activity during infusion of HS decreased significantly in the right masseter and temporalis (P<0.05). There was no significant difference in the position of the jaw at rest during infusions. However, the vertical opening distance was significantly decreased during infusion of HS at half-maximal and maximal opening (P<0.05). ⋯ It is concluded that experimental pain affects EMG-activity differentially in jaw-closing muscles in different opening positions of the jaw.

Randomized Controlled TrialGlutamate-evoked jaw muscle pain as a model of persistent myofascial TMD pain?
Compare pain-related measures and psychosocial variables between glutamate-evoked jaw muscle pain in healthy subjects (HS) and patients with persistent myofascial temporomandibular disorder (TMD) pain. ⋯ Glutamate-evoked pain responses in HS and persistent myofascial TMD pain have similar sensory-discriminative and affective-unpleasantness components but differ in psychosocial features. This study suggests that experimental designs based on glutamate injection into muscle can provide an appropriate model for elucidating persistent myofascial pain conditions.
