ULTRASONICS IN DENTISTRY

Dr. Amit Kumar Khajuria*

ABSTRACT

The term “ultrasound” applies to sound waves that vibrate at a frequency higher than the frequency that can be heard by human ear (20,000 hertz or 20 kilohertz). (20,000 hertz or 20 kilohertz). Principle of ultrasonic waves generation is to cause some dense material to vibrate very rapidly. These vibrations results in the vibration of surrounding air to vibrate with the same frequency and spread out in the form of ultrasonic waves. The uses of these waves ranges from detecting subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for structural changes, pathology and lesions to various therapeutic purposes. They have been used in various fields of medicine for early detection of structural changes in human body. Ultrasound has the advantage of being safe, non-invasive, cost effective and non-deleterious waves. Ultrasound is making its way in various areas of diagnosis and therapeutics in the field of dentistry.
