The Efficacy Of Glass Ionomer Hybrid As Orthodontic Brackets Adhesives To Inhibit Calsium Released Of The Enamel

Abstract

Composite resins are predominantly used to bond orthodontic
brackets onto teeth. These can lead to calcium released of the enamel surrounding
the brackets. Purpose : To observe calcium release during the use of adhesives
which release fluoride Method : This experimental study was design to determine
the calcium released after soaking in the acid solution. This in vitro study used
forty extracted human premolars (20 teeth were bonded with glass ionomer, and
20 teeth were bonded with glass ionomer hybrid). Half of the teeth in each group
were treated with fluoride application and the other half were not treated fluoride
application topically. Calcium released of the enamel was evaluated using
Spectrofotometer. Result :The results showed that there was a significant
difference between glass ionomer group without and with fluoride application
(p<0,005), and there was not significant difference (p>0,005) in the group of glass
ionomer hybrid without and with fluoride application topically. Conclusion :The
adhesive glass ionomer hybrid could prevent calcium released with or without the
usage of sodium fluoride.
