Clicking or popping sound during jaw movement. Option B
What is disk displacement?
A popping or clicking sound made when moving the jaw is indicative of "with reduction" TMJ (Temporomandibular Joint) disc displacement. When the jaw is moved in this condition, the articular disc, which serves as a cushion between the jawbone and the skull, may momentarily dislocate but will eventually return to its original position.
The disc moves as a result of this displacement, which frequently produces an audible sound. It's crucial to understand that "with reduction" means that the disc moves back into its natural position, as opposed to "without reduction," which means that the disc stays displaced and causes more serious symptoms like restricted jaw movement or permanent locking.
