It is a simple, reliable and short-term method that is frequently used to measure pain intensity in the clinic.

It includes a total of 20 items, with "0" indicating no limitation and "10" indicating severe limitation in each item, about the function of the TMJ during different activities, difficulty in chewing and jaw limitation.

Sleep bruxism reported by the individual was recorded.

Fonseca's Anamnestic Questionnaire (FAQ) was used. The questionnaire includes 10 questions about joint, head and neck pain, pain during masticatory activity, parafunctional habits, decreased joint motion, impaired occlusion and emotional stress. As a result of the questionnaire, the presence of TMD is accepted in patients with a score of 25 and above, and the severity can be classified as mild TMJ disorder (25-45), moderate TMJ disorder (50-65) and severe TMJ disorder (70-100).

Numeric Pain Scale (NAS): It is a simple, reliable and short-term method commonly used in the clinic to measure pain intensity. The patient is told that the most severe pain he/she feels in the TMJ region is 10, and if there is no pain, the pain intensity is 0. The participant was asked to say a number between 0 and 10 corresponding to the intensity of pain felt in the TMJ region.

Jaw Functionality Limitation Scale-20 was used. It includes a total of 20 items, with "0" indicating no limitation and "10" indicating severe limitation in each item, about the function of the TMJ during different activities, difficulty in chewing and jaw limitation. As a result of the questionnaire, it was reported that TMJ function was limited in individuals with a score of 5 and above.
