Comparison of Jaw Function and Mental Health Between Patients With Anterior Disc Displacement With and Without Reduction.

OBJECTIVES

Anterior disc displacement with reduction (ADDWR) and without reduction (ADDWOR) are two common clinical types of temporomandibular disorders. This study compared the levels of anxiety, depression, somatization, and jaw function of patients with ADDWR and ADDWOR.

MATERIAL AND

METHODS

From January 2023 to December 2024, 119 patients with ADDWR and 127 patients with ADDWOR were recruited from the Department of Rehabilitation Medicine at the Shanghai Ninth Peoples Hospital. All participants completed a single assessment, including a pain rating and several questionnaires to assess jaw dysfunction, depression, somatization, and anxiety levels. The scores and the grade distribution of somatization, depression, and anxiety of the two groups were compared.

RESULTS

Anxiety, depression, and somatization scores, as well as grade distributions, did not differ significantly between the ADDWR and ADDWOR groups. The scores for jaw function limitation, and pain on mouth opening and chewing were higher in the ADDWOR group than in the ADDWR group.

CONCLUSIONS

Patients with ADDWOR demonstrated more severely impaired jaw function and greater pain intensity during mouth opening and mastication compared to the ADDWR group. However, no significant differences were observed between the groups in terms of anxiety, depression, or somatic symptoms.
