 Difference between sonic and ultrasonic toothbrushes?

Sonic and ultrasonic toothbrushes are clubbed together when people
comment about them. In fact, all studies are considering them as if
they were similar. However, the sonic toothbrushes (sonicare, teledyne
and such) operate at 30000 vibrations per minute (500 per second) and
the ultrasonics operate at 1.6 Megahertz. Check these web sites:

Teledyne vibrates at 30000 strokes per minute:


Ultrasonex emits 1.6 MHz ultrasound:

Obviously, the effects must be different. What is the difference?
