Ultrasound: Radiation free imaging in dentistry

Ultrasonography is used to view internal body structures and organs. Ultrasonic images, also known as sonograms that are produced by sending pulses of ultrasound into tissue through the use of a probe, which carries a transducer containing material that produces a piezoelectric effect. The lower the frequency, the higher the penetration of tissues but the lower the potential image resolution. Intraoral USG makes it possible to visualize oral cavity organs, such as the sublingual gland and the submandibular duct, tongue, lips, tonsils, and soft palate, which are virtually impossible to image via conventional USG.
