The purpose of this study was the measurment of skin dose with thyroid gland, both sides of temporomandibular joint (TMJ) and eye in the X-ray examination of TMJ. The methods of X-ray examination were fluoroscopy, conventional lateral tomography, arthrotomography and arthrofluoroscopy. Objective cases were 37 patiants diagnosed with TMJ disorders clinically (10 males and 27 females).<br>Following results were obtained.<br>1. The exposure time of fluoroscopy at the arthrotomography was approximately 1.6-4.1 minutes.<br>2. The skin dose was 0.58-2.88mGy on the objective side of TMJ from the fluoroscopy at the arthrotomograpic examination. On the contrast, the skin dose of objective side of TMJ was 0.15-0.24mGy in fluoroscopy without contrast media.<br>3. The skin dose of exposure area from the fluoroscopy was measured by means of phantom, and it was 6.43mGy/min.<br>4. The skin dose at TMJ from the arthrotomography and tomography was respectively 15.6mGy and 13.6mGy/exposure.<br>5. From the arthrotomography of TMJ, skin dose at TMJ of objective side which suited at the exposure side was 62mGy.
