Properties, effects and clinical applications of ultrasound in periodontics: an overview
Bains, Vivek K. / Mohan, Ranjana / Gundappa, Mohan / Bains, Rhythm
Ultrasound is used in both the diagnosis and treatment of various diseases of the human body. Ultrasonography uses sound waves that reflect as echoes to produce images of structures within the body. It also has several applications in dentistry and in periodontics it is used to treat and maintain periodontal health. Through the cavitational effect and acoustic micro-streaming produced by oscillatory movements of ultrasonic inserts, mechanical debridement can be completed in a short time. The recent introduction of micro-ultrasonics and linear oscillating devices has improved mechanical debridement resulting in minimally invasive instrumentation. Ultrasonography plays a significant role in osteotomies and sinus lift procedures by its piezoelectric ultrasonic vibrations. Periodontal ultrasonography provides a non-invasive diagnostic method for measuring pocket depth and the assessment of periodontal health. In addition, low intensity pulsed ultrasound appears to be effective in periodontal healing and demonstrates the potential for periodontal regeneration.
