Design outcomes

Primary

Measure	Time frame
To evaluate changes in pain intensity, measured by the Numerical Rating Scale (NRS), and pain sensitivity, assessed by the Pressure Pain Threshold (PPT), in women with chronic painful temporomandibular disorder after a dietary intervention focused on reducing ultra-processed food consumption, compared with a control group.	—

Secondary

Measure	Time frame
To evaluate changes in pain-related functional disability (Graded Chronic Pain Scale – GCPS), sleep quality (Pittsburgh Sleep Quality Index – PSQI), anxiety and depression levels (Hospital Anxiety and Depression Scale – HADS), participants’ global perception of improvement (Patient Global Impression of Change – PGIC), and ultra-processed food consumption, measured by the Quest-NOVA platform, in women with chronic painful temporomandibular disorder after the dietary intervention, compared with the control group.	—
