Cleaning Technology Modalities

In addition to their power source, power toothbrushes differ in their cleaning technology mechanisms and can be categorized by the manner in which the brush head moves. Table 1 summarizes the various types of motion and modes of action in power brush movements.

Table 1. Comparison of Power Toothbrush Technologies.
Mode of Action Brush head motion Examples
Oscillating-Rotating Brush head rotates in one direction and then the other. Does not rotate in full circle. Oral-B Vitality
Oscillating-Rotating Pulsating Entire brush head oscillates, rotates, and pulsates (Figure 5). Oral-B Professional Care Series

Side-to-side (sonic) Brush head moves laterally in a side-to-side motion. Philips Sonicare
Multi-directional Brush sweeps from side-to-side and pulsates Colgate ProClinical
Counter-Oscillation Adjacent tufts rotate in opposite directions to each other. Interplak
Circular/Rotary Entire brush head rotates in a full circle moving in one direction only. Rotadent
Rowenta Dentiphant (RowentaWerke GmbH, Franz Alban, Stützer, Germany)
Teledyne (Teledyne Technologies Incorporated, Thousand Oaks, CA, USA)
