OBJECTIVE: To study the characteristic of joint sounds from temporomandibular joint (TMJ) without symptom during mandible movement.
METHODS: Joint sounds of 42 asymptomatic TMJ were recorded and analyzed with K6-I system during mandible movement, the waveform, frequency range, peak frequency and amplitude of joint sounds electrosonogram were studied.
RESULTS: Joint sounds were recorded in 25 joints of the 42 joints, 4 kinds of joint sounds were found according to the waveform, frequency range, peak frequency and amplitude of the electrosonography.
CONCLUSIONS: Joint sounds can be recorded in asymptomatic TMJ during mandible movement, 4 kinds of joints sounds were found according to the electrosonographic characteristics.
