This study was concerned with an evaluation of fluoride release from commercially available orthodontic bonding composite resins, known as Reliance®and Mirage Dual Cure®, which are claimed to release ionic floride. Forty-eight premolar teeth had brackets bonded with four different composite resins—Mirage Dual Cure®, Reliance®, Right-on®and Heliosit®. They were then immersed in a demineralizing solution. The amount of fluoride released from the composites into the solution was measured. The results indicated that Mirage Dual Curereg; released statistically significant amounts of fluoride over the first 2 days. A similar pattern was noted with Reliance®albeit releasing a lesser amount. From the third day onwards, fluoride release levelled out to concentrations similar to those of the two control materials, Right-on®and Heliosit®(i.e. 0·09 ppm). Fluoride-releasing composite resins, therefore, failed to demonstrate any potential long-term fluoride release within the ex vivo model. Even in the short term, the amount of fluoride released was very small. |
