Which set correctly lists the three cardinal features of TMD?

• A. Dizziness
• B. Orofacial pain, jaw dysfunction, joint noise
• C. Hearing loss
• D. Facial asymmetry

Answer: (B)

The main concept is the classic triad used to identify TMD: pain in the jaw region, problems with jaw movement, and sounds from the jaw joint. Orofacial pain reflects discomfort in the muscles that move the jaw or inside the joint itself, often brought on by chewing or jaw work. Jaw dysfunction shows up as limited opening, difficulty with chewing, or a jaw that deviates or locks during movement. Joint noise includes clicking or popping, and sometimes crepitus, as the joint components move.

So the set that lists orofacial pain, jaw dysfunction, and joint noise matches these core features. Dizziness, hearing loss, and facial asymmetry aren’t the defining triad of TMD, though they may appear with other conditions or less typical presentations.
