Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The modified six-minute functional chewing test (F-6MMT) was proposed as a tool to evaluate chewing ability and fatigue in patients with TMD. This test is an adaptation of a previously designed test in which subjects with mitochondrial pathology were evaluated; however, the subjects were not instructed to perform functional chewing during the test. In this version, modifications are added so that the test is as functional as possible, allowing chewing to be evaluated in a standardized way, and cut-off points established between healthy subjects and subjects with TMD in terms of chewing capacity in general and fatigue in particular. This study will follow standardized reporting guidelines and recruit participants from diverse clinical settings.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy Subjects
Subjects with TMD Screener score \< 3
Functional 6-minute mastication test
All participants will be evaluated in 3 different phases. First, they will respond to the online TMD screener questionnaire. Then, they will be presentally evaluated using the DC/TMD and finally they will undergo the functional 6-minute mastication test.
TMD subjects
Subjects with TMD screener score ≥ 3
Functional 6-minute mastication test
All participants will be evaluated in 3 different phases. First, they will respond to the online TMD screener questionnaire. Then, they will be presentally evaluated using the DC/TMD and finally they will undergo the functional 6-minute mastication test.
