Control group
Only occlusal splint was made for this patients.
Only intramuscular injection was applied to this patients. Intramuscular injectable form of Lidocaine Hydrochloride (20mg/ml, Jetokain Simplex, ADEKA, Samsun, Turkey) was injected. 0,3 ml was injected to all trigger points.
Intramuscular injectable form of Lidocaine Hydrochloride (20mg/ml, Jetokain Simplex, ADEKA, Samsun, Turkey) was injected. 0,3 ml was injected to all trigger points. Patients were started to use their occlusal splints in the evening of the injection day.
16 healthy volunteers was involved. Not given any treatment to these volunteers.
