Objectives: We aim to prove the central etiology hypothesis for bruxism, we plan examine structural components that contribute occurance of RMMA/Bruxism such as cortical, subcortical structures and a key roleplaying component, brainstem by investigating MEP, CSP, MIR (SP1 SP2) blink reflex (R1 R2) conduction time. Materials Methods: In this study, total 77 subjects investigated find any difference between two groups. The reflexes studied transcranial magnetic stimulation (TMS) electric stimulation. cortical silent period (CSP) evoked in contralateral masseter muscle TMS. Central motor conducting times were evaluated. Results: absence SP2 (component MIR), R2 reflex) latency left APB (abductor pollicis brevis) F wave are found be significantly different Conclusions: As result our loss component prolongation localization circuits brainstem, although their pathways separate, bruxer suggested pathophysiology may have origin most bruxers.
