Treatment and study plan

Primary outcomes

  1. Assessment of Presence and Severity of Temporomandibular Dysfunction

    Time frame: an average of 6 months

    Fonseca Anamnestic Index, reported as a reliable and valid index, will be used to determine the presence and severity of TMD. The total score ranges from 0 to 100. The total score of the index allows the following classification: no TMD (≤ 15), mild TMD (20-40), moderate TMD (45-65), and severe TMD (70-100).

Secondary outcomes

  1. Oral Habits

    Time frame: an average of 6 months

    The Oral habits checklist, a questionnaire recommended for the assessment of parafunctional behaviors, will be used.

  2. Food Consumption Frequency

    Time frame: an average of 6 months

    The frequency and amount of food groups or nutrients consumed will be questioned. Frequency of consumption can be given as day, month or week.

  3. Eating Behavior

    Time frame: an average of 6 months

    The Adult Eating Behavior Scale will be used. There are 8 sub-dimensions and a total of 35 items in the scale. It is scored with a five-point Likert. The score obtained shows the tendency towards the relevant behavior. There is no scale measuring the total score.
