Better dental decay detection using ultrasound:

Executive Summary
More efficient detection of dental decay is possible through a new ultrasound process developed at the Fraunhofer-Institut fur Biomedizinische Technik (IBMT) in Germany. Ultrasound detects differences in the density of the tooth; an image of the tooth is then displayed on a monitor which gives a more accurate picture of any decay present. Traditional X-ray examinations often miss decay under or behind fillings or in the space between teeth. Clinical tests are planned in Berlin in two years' time.
