Improved biofilm removal using cavitation from a dental ultrasonic scaler vibrating in carbonated water

The use of cavitation for improving biofilm cleaning is great interest. There no system at present that removes the from medical implants effectively and specifically dental implants. Cavitation generated by a vibrating ultrasonic scaler tip can clean biomaterials such as However, process must be significantly accelerated clinical applications. In this study we investigated whether could increased, operating in carbonated water with different CO2 concentrations. around an was recorded high speed imaging. Image analysis used to calculate area cavitation. Bacterial grown on surfaces its removal imaged camera using still water. increases increasing carbonation. also started earlier tips when they were compared non-carbonated Significantly more removed operated Our results suggest increase accelerate scalers situation thus improve other biomaterials.
