TMJ noise is a sign of TMJ dysfunction. But it is sometimes difficult to distinguish objectively the side at which the TMJ noise is occurring. This study examined a method to distinguish objectively the side of TMJ noise. We used a three-directional accelerometer to measure the TMJ noise in 6 subjects. 1. The lateral amplitude of the occurring side was as much as the other side at times. 2. The time difference between the peaks of the three directions of the occurring side was shorter than the other side. 3. The cause of this time difference could be due to the viblation of the TMJ noise traveling through many routes of the boney structure of the head from the occurring side to the other side. 4. These results suggest that the use of a three-directional accelerometer is a reliable method in distinguishing at which side the TMJ noise is occurring.
