New research identifies role of tiny bubbles in teeth cleaning
from Medical News Today
Research into the science behind ultrasonic scalers, used by dental professionals to remove built up plaque, has identified that the formation of tiny bubbles around the head is key to the cleaning process. The bubble formation, or cavitation, of water around the head of the scaler was observed using high speed cameras. Scalers of differing power, and head shape, were used and compared to quantify the patterns of cavitation.
