Abstract :
Ultrasound is a well-established tool for medical imaging but it has yet to emerge in routine use in dental diagnostics. Nevertheless, it was shown in the late 1970s that ultrasound can be used to probe the internal structures of teeth, and more recently to observe surface changes due to caries and acid erosion.
