摘要: ABSTRACTThe surface vibrations of 42 temporomandibular joints (TMJ) with degenerative joint disease (DJD) and/or perforation the disk were evaluated using electrovibratography and compared to 83 normal TMJ imagings 61 meniscal displacement without reduction. Through frequency spectrum analysis, TMJs DJD showed higher vibration energy above 350–450 Hz between 100–150 300–450 Hz. The presence did not seem affect characteristic when associated DJD. A threshold was set for total as described in our previous report used a parameter order separate patients internal derangement from pool dysfunction (diagnostic specificity = 75%, diagnostic sensitivity 80.2%). Using this criteria, following correctly identified DJD: a) 100% with...
