How does DC/TMD improve upon RDC/TMD?

How does DC/TMD improve upon RDC/TMD?

• A. It provides updated, standardized Axis I diagnoses and expanded Axis II measures for psychosocial status and pain impact.
• B. It provides different Axis I diagnoses and removes Axis II.
• C. It eliminates Axis II entirely.
• D. It adds imaging criteria to Axis I.

Answer: (A)

DC/TMD’s improvement comes from updating how diagnosis is made and expanding the evaluation of the patient’s experience. Axis I now uses updated, standardized, evidence-based criteria for diagnosing TMD subtypes, replacing older RDC/TMD approaches with clearer, more consistent clinical diagnoses. At the same time, Axis II is broadened to include more comprehensive measures of psychosocial status and the impact of pain on daily functioning, giving a fuller picture of how TMD affects a patient’s life. This combination enhances reliability across clinicians and studies and supports more informed treatment planning. It does not introduce new imaging criteria or remove Axis II—the advance is in the revised diagnostic criteria and the expanded psychosocial/pain-impact assessment.
