Abstract

Click sounds in cases other than ADDw/r were studied in order to clarify the specificity thereof. Three subjects were diagnosed by double contrast arthrography for adhesion in the lower joint cavity, posterior displacement of the disk with reduction at the maximum opening of the mouth and incoordination of the disk, respectively.<BR>Three joints of the subjects were compared with 20 joints of ADDw/r with click sounds as controls. The character of TMJ sounds and condylar movement were quantitatively studied using our original analyzing system.<BR>The results were as follows:<BR>1. MRI findings were false negative.<BR>2. There were click sounds with condylar movement deflection or sounds similar to reciprocal click sounds in cases other than ADDw/r; therefore, it was impossible to diagnose TMD only by click sounds at opening and closing of the mouth.<BR>3. Subject 1 had the same position for opening and closing sounds, and subjects 2 and 3 had markedly distinct sounds or condylar movement deflection at closing. These were different from those of ADDw/r.<BR>4. In the 3 cases, these characteristics enhanced distinction from ADDw/r.
