“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. The team believe that the methods developed in the study will help to test new instrument designs to maximise cavitation, with the aim of designing ultrasonic scalers that operate without touching the tooth surface. By doing so, the process of teeth cleaning at the dentist would become both less painful and more effective.”
