What is NOT a characteristic of disc displacement with reduction?

Disc displacement with reduction is a condition affecting the temporomandibular joint (TMJ) where the articular disc of the joint is displaced but can be reduced back into its normal position during movement.

The characteristics of this condition include the presence of reproducible joint noises, such as clicking or popping, during mandibular movements. These noises occur because the disc displaces and then reduces as the jaw opens and closes. Additionally, soft tissue imaging, such as MRI, often shows the displaced disc returning to its proper position during motion, indicating the dynamic nature of the displacement. It is also common for patients with this condition to experience pain or deviation during movement, reflecting the underlying joint dysfunction.

On the other hand, a characteristic that does not align with disc displacement with reduction is the revelation of a non-improving displaced disc through soft tissue imaging. In cases of disc displacement without reduction, the disc remains displaced, which does not exhibit the aforementioned characteristics of movement and recovery seen in displacement with reduction. Thus, it is the imaging revealing no improvement of the displaced disc that diverges from the traits of disc displacement with reduction, making it the correct response in this context.
