Efficacy of a fluoride-releasing orthodontic primer in reducing demineralization around brackets: an in-vivo study.

Abstract

INTRODUCTION:

A new, highly filled primer is currently marketed as a fluoride delivery system effective in reducing white spot lesions in orthodontic patients. However, no studies in the literature support this claim. The purpose of this in-vivo study was to investigate the retention and the efficacy of this primer in reducing the formation of white spot lesions.

METHODS:

In each patient for whom premolar extractions were planned (n = 22), 1 premolar was randomly chosen as the experimental tooth for the application of the fluoride delivery system (Opal Seal; Ultradent Products, South Jordan, Utah), and the contralateral tooth was assigned as the control to receive the standard treatment (Transbond XT; 3M Unitek, Monrovia, Calif). After the bonding procedures, separators were placed around the premolar brackets to encourage plaque retention over 8 weeks. After the extractions, the tooth surfaces were evaluated visually and with microhardness techniques for demineralization. Primer retention was also investigated.

RESULTS:

There were no statistically significant differences in the numbers of white spot lesions between the 2 groups. The primer retention was calculated as 50%.

CONCLUSIONS:

The results indicated no significant difference between the efficacies of the fluoride-releasing primer and the control primer in reducing demineralization over the duration of the study.
