See the proof: The Cavitron 300 Ultrasonic Scaling System removes 50% more active biofilm as compared to hand scaling.¹
Ultrasonic Scaling (Left)
Pale purple all over = very little biofilm remaining
Hand Scaling (Middle)
Pale purple areas = removed by hand scaler
Dark purple = remaining biofilm not removed
Control: Untreated (Right)
Dark purple all over = high biofilm remaining
