What outcome measures are commonly used to assess TMD disability and function?

• A. Jaw Functional Limitation Scale (JFLS), pain scales, and quality-of-life measures like SF-36.
• B. Complete blood count and metabolic panel.
• C. Ultrasound of the TMJ only.
• D. Genetic testing panels.

Answer: (A)

The key idea is using patient-reported outcome measures to quantify how TMD limits daily function and how pain affects quality of life. The Jaw Functional Limitation Scale focuses on actual jaw-related activities—chewing, movement, and speaking—highlighting specific functional disabilities caused by TMD. Pain scales capture how intense the pain is, which is a major driver of functional limitation and a common target for treatment. Quality-of-life tools like SF-36 assess broader physical and mental well-being, showing how TMD affects daily life, social participation, work, sleep, and mood. Together, these measures give a comprehensive view of how TMD disrupts function and overall well-being, beyond what imaging or lab tests can show. Other options don’t assess disability or function directly: routine blood tests aren’t about jaw function, imaging of the TMJ provides structural info but not functional impact, and genetic panels don’t measure disability or daily functioning.
