Repair of orthodontically induced root resorption by ultrasound in humans.

Root resorption is an adverse outcome of orthodontic tooth movement. In addition to the iatrogenic response and compromising the crown-root ratio, root resorption has led to increased malpractice litigation against orthodontists. A clinically acceptable method of treating root resorption has not been validated in the literature to date.

Growth modification of the rabbit mandible using therapeutic ultrasound: is it possible to enhance functional appliance results?

Previous studies have shown that functional appliances can enhance mandibular growth when applied during the active growth period. However, besides patient compliance problems with bulky appliances and prolonged treatment demands, there is contradictory evidence that functional appliances have a significant long-term effect. Is there a method to enhance the growth response and improve the long-term success of functional appliances? Previous studies have also found that therapeutic ultrasound (US) can stimulate cartilage and bone growth.
