About this study
Official title: Investigation of the Relationship Between Temporomandibular Joint Dysfunction Prevalence and Oral Habits, Food Consumption Frequency and Eating Behaviour in University Students: A Cross-Sectional Study
This study was planned to investigate the prevalence of TMD in university students and to determine possible predisposition factors by evaluating oral habits, food consumption frequency and eating behaviors thought to be related to TMD.
Read the detailed description
No study has been found examining the relationship between temporomandibular joint dysfunction (TMD) and oral habits, food consumption frequency and eating behavior. In this context, it is thought that understanding the relationships mentioned may provide different perspectives and help develop an effective treatment program.

What is being measured
The primary outcome is the main question the study is designed to answer.
Assessment of Presence and Severity of Temporomandibular Dysfunction
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).
Measured: an average of 6 months
Secondary outcomes (3)
Oral Habits
The Oral habits checklist, a questionnaire recommended for the assessment of parafunctional behaviors, will be used.
Measured: an average of 6 months
Food Consumption Frequency
The frequency and amount of food groups or nutrients consumed will be questioned. Frequency of consumption can be given as day, month or week.
Measured: an average of 6 months
Eating Behavior
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.
Measured: an average of 6 months
