The aim of this study was to determine the relationship between autonomic nervous system activity and tonus, stiffness and elasticity of temporalis and masseter muscles in individuals with bruxism and to compare them with healthy controls.
Individuals diagnosed with bruxism and healthy individuals as a control group will be included in the study. Firstly, the purpose of the research and evaluation methods will be explained to the participants. Individuals who volunteer to participate in the study and meet the inclusion criteria will be included. Approval will be obtained from the individuals to be evaluated with the 'Informed Voluntary Consent Form'. Individuals will then fill in the Descriptive Data Form. The intensity of pain in the masticatory muscles of all participants at rest and during chewing will be measured by Visual Analogue Scale, Autonomic Nervous System activity (heart rate variables) will be measured by Polar H10 chest strap, and the tonus, stiffness and elasticity of the temporalis and masseter muscles will be measured by Myoton device. The evaluations are planned to take an average of 20 minutes for each participant. The evaluations of the participants will be made only once and will not be evaluated again.

The pain intensity of the participants will be assessed using the Visual Analogue Scale, which is a simple, reliable and short-term method commonly used to measure pain intensity in the clinic. The participant is told that the most severe pain he/she experiences is 10 and if there is no pain, the pain intensity is 0. The participant will be asked to tick a number between 0 and 10 corresponding to the intensity of pain felt in the masticatory muscles at rest and during chewing.
All participants included in the study will undergo a 5-minute test with the Polar H10 chest strap device for autonomic nervous system activity assessment (heart rate variability assessment). The data obtained after the measurement will be analysed with Kubios software. Stress index (cardiovascular system stress), PNS index (parasympathetic nervous system dominance), SNS index (sympathetic nervous system dominance), LF power (sympathetic activity), HF power (parasympathetic activity) and LF/HF ratio (sympathetic/parasympathetic balance) parameters will be used in the evaluation of HRV in Kubios programme.

Masticatory muscles biomechanical properties assessment
The Myoton PRO device will be used to objectively assess the biomechanical properties of the participants' masticatory muscles. The masticatory muscles will be evaluated bilaterally in the sitting position. Three measurements will be recorded at one second intervals and the average value will be used for analysis.
