During bite test, pain on the opposite side indicates what?

• A. Nerve damage
• B. Muscle involvement
• C. Vascular issue
• D. Joint involvement

Answer: (D)

During a bite test, where the patient feels pain helps distinguish the source of TMD pain. If the pain is reported on the side opposite the bite, it points to joint involvement in the contralateral temporomandibular joint. This happens because unilateral biting stresses both joints, and pathology within the opposite joint (disc, capsule, or articular surfaces) tends to produce pain that is perceived on that opposite side. In contrast, muscular pain is typically felt on the side that is actively contracting to bite. So contralateral pain during the bite test indicates a TMJ joint problem on the opposite side.
