Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with tooth disease that requires a root canal.

How it Works
This novel technology sends beams of focused ultrasound energy into the cleaning fluid which forms cavitation bubbles. The negative pressure that comes from the cavitation greatly enhances the cleaning of the nerve root.

Conventional techniques effectively clean 29% of the nerve root, and passive ultrasound techniques may achieve 80%. The focused ultrasound cavitation bubble technique achieved a cleanliness level reported at greater than 97%. For certain patients, focused ultrasound use may improve the success of this procedure and also enhance the patient’s comfort.

Focused ultrasound also preserves dentin maintenance compared to mechanical techniques and easily accommodates the variable structure of the nerve root.

For more information, please see the patient information site or the manufacturer’s (Sonendo) website.

Clinical Trials

At the present time, there are no clinical trials recruiting patients. However, a 12-month study was completed recently. 

Regulatory Approval and Reimbursement

This treatment is not yet approved by regulatory bodies or covered by medical insurance companies.
