Name two validated outcome measures used in DC/TMD Axis II to assess pain-related disability.

• A. Graded Chronic Pain Scale (GCPS) and Fonseca Disability Index
• B. Visual Analog Scale and range of motion
• C. MRI and CT imaging findings
• D. Pain diary and sleep quality index

Answer: (A)

In DC/TMD Axis II, the focus is on how pain from TMD affects function and daily life, using patient-reported measures that are validated for this purpose. The two best choices are the Graded Chronic Pain Scale and the Fonseca Disability Index. The Graded Chronic Pain Scale combines measures of pain intensity with how much pain interferes with usual activities, producing a disability grade that reflects the overall impact of chronic pain on function. The Fonseca Disability Index is a concise, TMD-specific questionnaire that assesses functional limitations and overall disability attributable to TMD symptoms. Both are well-validated, widely used in both research and clinical practice, and designed to capture pain-related disability rather than just pain intensity or structural findings. Why the others aren’t the best fit: a simple pain rating scale measures how much pain is felt but not how that pain limits function, which is central to Axis II. Range of motion tests physical capacity but aren’t validated self-report measures of disability. Imaging findings like MRI or CT relate to anatomy and are part of Axis I assessment, not Axis II. A pain diary and sleep quality index can provide useful context, but they aren’t standard, validated, two-measure instruments specifically designated for assessing pain-related disability in DC/TMD Axis II.
