Joint vibration records were made with JVA (Biopak system BioResearch , Inc., Milwaukee, WI) device during the opening and closing movements. The recordings were made before and after occlusal splint treatment for three months in patients with bruxism. The recordings of individuals in control group was made two times at three months intervals. Also clinical evaluation was made with questionnaire forms.
