Ultrasonics (Applications of Ultrasound in Orthodontics)

Ultrasound are sound waves with frequencies higher than those audible to humans. They can be used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for possible pathology and lesions. They are also being used for therapeutic purpose. They have been used extensively in various fields of medicine.. Ultrasound has been recognized for having several advantages-safe, non-invasive, patient friendly and less expensive approach. But their role in dentistry especially in orthodontics is limited. Ultrasound makes its use both in various areas of diagnosis and therapeutics, but very little importance is given to it in the field of orthodontics.
