Data obtained by computer tomography of the TMJ were compared with those of clinical and instrumental analyses of function. 25 females and 37 males aged between 19 and 47 years (mean age, 24.8 years) were examined. None of the patients complained of functional problems subjectively, but clinical analysis of function showed several signs of stomatognathic dysfunction to be present. Results of CT did not correlate with those of clinical and instrumental analysis.
