The "story" of ultrasonography in dentomaxillofacial diagnostics is a journey from observing natural biology to developing radiation-free, high-precision tools for modern dentistry. The Origins: From Bats to Teeth
Long before X-rays, the story began with in 1794, who performed experiments on bats that revealed their use of sound for navigation. In 1880, Pierre and Jacques Curie discovered the piezoelectric effect—applying electricity to quartz crystal to produce ultrasonic waves. By 1928, physicist S.Y. Sokolov conceptualized using these sound waves for imaging. Modern Evolution in Dentistry Ultrasonography in Dentomaxillofacial Diagnostics
Today, diagnostic ultrasonography (USG) has evolved into an indispensable tool that offers a non-invasive, radiation-free alternative to traditional X-rays. It is particularly valuable for imaging: the story began with in 1794
