Objectives:To analyze changes in enamel and surface roughness after remineralization with S–PRG filler–containing toothpaste or artificial saliva, following the bonding/debonding of orthodontic buttons and removal of residual cement.

Methods:Orthodontic buttons were bonded to twenty premolars by Transbond XT(TX) or BeautyOrthoBond2(BO2). Buttons were debonded and residual cement removed. Teeth were subdivided into four groups  They were remineralized with toothpaste containing S–PRG filler or with artificial saliva. Confocal microscopy was used to determine the enamel changes.

Results:Significant (P <.05) enamel changes was observed after resin removal in the TX and BO2 groups. Remineralization with S–PRG filler–containing toothpaste resulted in a significant increase in enamel volume. There was no change in enamel volume after remineralization with saliva.

Conclusions:Use of S–PRG filler–containing toothpaste increases enamel volume after the removal of residual cement following orthodontic buttonsbonding/debonding. No changes were observed following artificial saliva.
