Impacted tooth extractions are the most frequently performed procedure in oral surgery. Complications such as pain and trismus are frequently observed after surgery. Pain, especially after surgery, causes serious discomfort to the individual. These complications negatively affect the daily lives of individuals. Decreased sleep quality, increased anxiety, fear of moving the jaw joint, decreased quality of life, and loss of labor are among the examples that can be given. It is important for individuals to have a more comfortable process in the early period after surgery. During this period, individuals receive pharmacological treatment; however, non-pharmacological approaches should not be ignored. Evaluation of the effects of relaxation exercise and virtual reality application applied after impacted third molar surgery on pain, trismus, sleep, kinesiophobia, and anxiety levels.

Impacted third molar surgery is one of the most common procedures performed by oral, dental and maxillofacial surgeons. During surgical removal of teeth, trauma may occur due to the narrowing of the area and insufficient visibility, the position of the teeth and the hardness of the bone structure. In addition, this surgical procedure leads to various complications since it requires intraoral intervention. It has also been stated that most complications are triggered by the inflammatory process after surgery and are reported with varying frequencies. As a result of trauma that may occur in soft and bone tissue, symptoms such as pain, swelling and trismus may occur. Post-surgical pain is an acute type of pain that begins with surgical trauma, gradually decreases and ends with tissue healing. This pain triggers a stress response in the sympathetic nervous system, causing an increase in muscle tension. Another situation encountered after surgery is an increase in anxiety. Anxiety is a distinct state of restlessness caused by fear, distress or apprehension. Individuals are afraid of surgery even if they think surgery is necessary to regain their health or improve their quality of life. The incidence of complications is higher in individuals with high levels of anxiety after surgery.

In the evaluation; Modified Dental Anxiety Scale, Visual Analog Scale, Maximum Active Mouth Opening Measurement, The Tampa Scale for Kinesiophobia for Temporomandibular Disorders, Electromyography (EMG), Turkish version of the Visual Analog Sleep Scale, State and Trait Anxiety Scale will be used.

Individuals participating in the study will be included in one of 3 groups. Group 1 will be Relaxation Exercise, Group 2 will be Virtual Reality Application in addition to Relaxation Exercise, and Group 3 will be the control group.
