Abstract

OBJECTIVE:

We compared joint pain (JP) in patients diagnosed with and without articular disc displacement without reduction (ADD) based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and identified the characteristics of each JP.

STUDY DESIGN:

Fifty-eight patients with restricted mouth opening and pain in temporomandibular joint (TMJ) and with a magnetic resonance imaging diagnosis of ADD were selected. Diagnosis of ADD + JP and nonADD + JP was made with the use of the RDC/TMD.

RESULTS:

A multiple regression analysis of the data disclosed a positive correlation between range of motion on maximum assisted mouth opening and visual analog scale (VAS) (severity of JP) in the ADD + JP group, and between chronic pain grade (CPG) and VAS in the nonADD + JP group. A significant difference was observed between ADD + JP and nonADD + JP groups in CPG; CPG was higher in the nonADD + JP than in the ADD + JP group.

CONCLUSIONS:

It is suggested that JP related and unrelated to ADD can indicate different types of disease.
