What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Patients suffering from temporomandibular joint disorder | each patient will complete the translated in the greek language JFLS-20 and the 14-item Oral Health Impact Profile (OHIP-14) twice |
What is being measured
The primary outcome is the main question the study is designed to answer.
Jaw Functional Limitation Scale-20
Patients suffering from TMJD will be assessed with the JFLS-20 for the validation and cultural adaptation of the JFLS-20 for the assessment of jaw functional limitation
Measured: "From enrollment (baseline) to the end of assessment at 1 week"
