Abstract
Recording both Electromyographic (EMG) and temporo-mandibular joint (TMJ) sounds using surface (SEMG) and intramuscular electrodes can prove to be extremely beneficial for both dental research and clinics. SEMG can provide a comprehensive overview, while needle EMG can be used to analyze the functioning of a specific muscle or muscle component. Amplifiers should have various power level options and a flat frequency response. When using needle electrodes for EMG recording, it is crucial to have a sampling rate of at least 10,000 Hz to capture the necessary waveforms.
