The CUSA is a device of modern periodontal treatment that claims to be a breakthrough in minimal invasion surgical technique. While repairing a ship's propeller in 1916, scientist Lord Rayleigh discovered the effect of cavitation. This device, like others, uses low frequency ultrasonic radiation to dissect or split tissues with low fibre content. Ultrasonic pulses in the 23 kHz range are used to create cavitations in tissue a hollow 3 mm tip vibrating at 23,000 times per second delivers this mechanical energy. CUSA is a surgical device that was developed for ophthalmology but has since gained widespread acceptance in a number of medical disciplines, including neurosurgery, general surgery, gynaecology, urology, and neurotology. This equipment cause, Biofilm disruption and cell stimulation for non-surgical treatment of infrabony defects, as well as ultrasonic debridement and flapless therapy, are said to be effective. Using this aspirator increases safety and quality while decreasing operational time. There are no known contraindications, but there are financial and personal constraints. As a result, this strategy appears to be a viable option for improving non-surgical minimally invasive therapeutic procedures.
