WHY Use Sonography?
Bone transmission of sound is so rapid that unilateral study of joint sound with a stethoscope may not even discern which side the sound is coming from. Further, sounds studied in this manner are subjective and not documented. Data captured by means of sonography not only record joint sounds from both TM joints simultaneously, the information can be played back at will. The dentist can analyze this recorded information in a number of ways that may yield additional insight regarding joint status and joint function. The test can be used as a very quick assessment of joint status and to document patient response to treatment.
