| Aim of the study: Evaluation of cyclic shear bond strength (CSBS) of orthodontic brackets bonded to deglazed porcelain surface etched with hydrofluoric acid. Material and methods: Twentydeglazed HFA etched ceramic disks were divided equally in to two groups (n=10).In group 1 the ceramic disks was treated with HFA then thin coat of Transbond XT primer+Silane was applied u onto its surface. In group 2 Single bond universal was applied on ceramic disks. Using Transbond XT adhesive to bond metal brackets to all ceramic disks. After bonding,all ceramic diskswere subjected to test the cyclic shear bond strength.ANOVA test was used to compare between the two groups. Results:There weresignificant difference between the 2 groups(P<0.05). Conclusion:Single bond universal could be used successfully instead of Silane. | ||||
