| 1. Electromyography of the muscles was measured using an electromyography device (2-channel electromyograph MYOQUICK®, Micromed®, Rome, Italy) before treatment (t0) and 2 weeks after treatment (t1). Regarding the masseter muscle, custom gel (EEG Paste, AQUA Medical, Istanbul, Turkey) was placed on the surface electrodes, with an interval of approximately 3 cm between them, parallel to the fibers of the masseter muscle, in the middle of the muscle, and fixed for accurate measurement. While the ground electrode was placed in the middle of the forehead, its purpose was to distort and remove noise. The patient bit hard on their teeth to clench in the central occlusal position. The measurement was conducted to obtain three values, the highest and the lowest, and the difference was estimated in (µv). Regarding electromyography of the lateral pterygoid muscle, the first surface electrode was placed in front of the ear, the ground electrode was placed in the middle of the forehead, and the EMG Needle was used as a deep electrode for electromyography first, followed by measurement and injection. 2. Bruxism: the participants were asked whether they clenched their teeth during the day or while sleeping and if anyone noticed that they clenched. They were also asked if they had a stiff jaw or facial spasm when they woke up. The questionnaire has four close-ended questions. The scoring was (0) for each no answer and (1) for each yes answer, then presented as a percentage. Patients' answers to the questionnaire were recorded five times before treatment (t0), 2 weeks after treatment (t1), 6 weeks after treatment (t2), 3 months after treatment (t3), and 6 months after treatment (t4). | — |
