The experiments were performed on Wistar rats anaesthetized with urethane (1g/kg). The vibration (120-150Hz, 1mm) was applied to the mandible and the reflex activity was recorded bilaterally from the masseter, temporal and digastric muscles. Experiment I: To establish an experiment model, effective parameters such as vibration frequency, direction of vibration, and jaw position (muscle length) to elicit TVRs were determined. Experiment II: Using the established experimental model, We examined effects of hypertonic saline (5%) and mustard oil (20% in mineral oil) injection into the temporal muscle on TVRs. A vibration frequency of 150Hz in horizontal direction and jaw opening position of 7mm apart at the opposing incisor were determined to be the most effective parameters for TVRs. Both chemicals injected into the temporal muscle reduced the TVR amplitude, and the effect of mustard oil was more than that of hypertonic saline. However, the modulatory effect varied among the muscles tested. In conclusion, effective parameters to elicit TVRs were determined and the change in sensitivity of muscle spindles was suspected to be a factor that affect the response of TVRs to noxious stimuli applied to the jaw closing muscles.", "subitem_description_type": "Abstract"}, {"subitem_description":
