The Effect of Bruxism on Balance

Short Form 36 (SF-36)

Quality of Life Scale/Short Form-36 (SF-36): SF-36 was developed by the Rand Corporation to obtain information about the health status of the individual. It was translated into Turkish by Koçyiğit and his colleagues, who conducted a validity and reliability study. It consists of eight sub-dimensions and 36 items. The sub-dimensions consist of physical function, social function, physical role difficulty, emotional state difficulty, mental health, energy/vitality, pain, and general perception of health. A score of "0" represents the worst health status, while "100" represents the best health status. Each sub-dimension is evaluated individually without calculating the total score.

Pittsburgh Sleep Quality Index

Pittsburgh Sleep Quality Index (PSQI): It is a 24-question scale developed by Buysse et al. in 1989 that evaluates sleep quality in the last month. A Turkish validity and reliability study was performed in 1996. The sum of the scores of seven components, subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, sleep medication use, and daytime dysfunction, gives the total score index. The total PSQI score ranges from 0 to 21; a score above 5 points indicates poor sleep quality; a score of 5 points or less indicates good sleep quality. The PSQI is one of the most commonly used scales for evaluating sleep quality. The validity of the use of this index in sleep disorders has been tested before, and it has been frequently used in studies on bruxism.

Beck Anxiety Inventory (BAI)

This scale's 21 items describe the most typical symptoms of anxiety disorders. It was developed to measure the intensity of anxiety symptoms in clinical populations. It asks respondents to indicate how much they have been affected by each symptom during the last week, on a scale from 0 (Not at all) to 3 (Severely - I could barely stand it). Total scores are the sum of all item scores, and range from 0 to 63; higher scores indicate higher anxiety. When this instrument was developed, the goal was to more easily discriminate between anxiety disorders and depressive disorders, whose symptoms frequently overlap on other assessment tools.

Fonseca Anamnestic Index

Fonseca Anamnestic Index (FAI): It was developed in 1994 by Fonseca et al. and consists of 10 questions investigating pain in the head and TMJ. Turkish validity and reliability of the test was performed by Kaynak et al. The questionnaire includes various questions about joint, head, and neck pain; joint movements; parafunctional habits; impaired occlusion; and emotional stress. Participants were asked to answer "Yes" , "Sometimes" , or "No" to each question, and TMD was classified as none, mild, moderate, or severe according to the total score.
