We conducted a retrospective study of 30 patients who sought.

Service of Dentistry, University Cruzeiro do Sul, with a diagnosis of temporomandibular disorders (TMD) in the period from January 2002 to January 2006.

The images obtained through nuclear magnetic resonance offer a better visualization of the disturbances and anatomy of TMJ when compared to other auxiliary diagnosis methods.

Aim: Check the signals and symptoms relationship through clinical exams of TMD patients with results obtained from the nuclear magnetic resonances.

Materials and methods: Thirty patients with signs and symptoms of temporomandibular disfunction were submitted to clinical evaluations and subsequent exam of magnetic nuclear resonance.

Results: There was a respectively result of 56.7% (Kappa = 0.1) and 56.7 (Kappa = 0) in left and right sides.

Conclusion: We found no relation between the disc displacement clinical diagnosis and the magnetic nuclear resonance.

Conflict of interest: None declared.
