title: Effect of ultrasonic ZnPO-4 cement removal on band adhesion and cement solubility under orthodontic bands.
abstract: The use of ultrasonic energy to remove excess ZnPO-4 cement from orthodontic bands reduces the solubility of the cement but does not affect band adhesion unless excessive band contact is made. Excessive band contact weakens band-to-tooth adhesion. The solubility of the cement is increased by decreasing the pH and is increased when organic anions capable of binding metal ions are present.
