Which of the following statements about disc dislocation is incorrect?

The statement that is deemed incorrect is that consistent joint clicking is seen in cases of disc dislocation without reduction. In cases of disc dislocation without reduction, the disc is displaced and not in its proper alignment, which often leads to a lack of consistent joint sounds, such as clicking. This is because the disc does not return to its normal position during mandibular movements, preventing the typical clicking sound that occurs when the disc moves back into alignment.

The other statements are accurate and reflect typical clinical observations associated with disc dislocation. A history of clicking often precedes the sensation of the jaw catching, suggesting that the displacement of the disc usually occurs over time and may start with intermittent clicking. The presence of a loud click often indicates that the disc has recaptured itself during the mouth's opening, a phenomenon commonly observed in disc dislocations that may occasionally reduce. Additionally, with significant dislocation without reduction, the range of mandibular opening can indeed be limited to around 25 to 30 mm, reflecting restricted movement due to the displacement of the disc. Therefore, the nuances of disc dysfunction dynamics are crucial to understanding these clinical features.
