Evaluation of fluoride varnish and its comparison with pumice prophylaxis using self-etching primer in orthodontic bonding--an in vivo study.

The aim of this study was to evaluate the use of fluoride varnish as a prophylaxis method with self etching primer (SEP) and its comparison with pumice before orthodontic bonding. Thirty seven orthodontic patients participated in a prospective clinical trial. A split mouth technique was used in each patient, one quadrant was assigned to fluoride varnish and the contralateral quadrant to pumice prophylaxis.
