Crystal growth bonded composite restorations. A bond strength evaluation.
Sixty maxillary central incisors whose incisal angle were restored with composite resin after acid etching surface treatment and various crystal growth surface treatment were subjected to bond-strength evaluation in universal testing machine, after 24 hours. The acid etching was done with 37% orthophosphoric acid. The crystal growth agents (CGA) were 2%, 5% and 10% formic acid saturated with ammonium sulfate. The mean bond strength of composite restoration treated with 5% CGA were not statistically from acid etched restorations.
