Use of low intensity pulsed ultrasound and mechanical vibrations to accelerate tooth movement in animals.
| Author | Sample | LIPUS and vibration specification | Duration | Results | Movement in experimental group | Movement in control group |
|---|---|---|---|---|---|---|
| Xue et al. [45] | 48 rats divided into 6 groups |
Frequency 1.5-MHz; intensity 30 mW/cm2 | Burst of 200 µs followed by pause of 800 µs 20 min/day for 14 days | 55%, 36%, and 45% acceleration in tooth movement on days 5, 7, and 14, respectively | 1118 µm ± not given |
773 ± not given |
