Effect of Acid Etching Duration on Resin Bond Strength to Primary Enamel Using 37% Phosphoric Acid


Abstract in English

Etching by phosphoric acid is considered an important factor to achieve resin bonding to Primary enamel. Bond strength was significantly higher in the third group (etching for 35sec) than the other groups (etching for (15), (25), or (45)sec). There were no significant differences in bond strength between etch durations: (15), (25), or (45) sec.
