The Effect of Etching Time with Phosphoric Acid on The Bonding Strength of Composite Restoration in Dentine of Primary molar


Abstract in English

The etching primary teeth dentin is more important factors for bonding composit with primary teeth dentin. objective: The aim of this research is to know the effect of time etching with the phosphoric acid 37% by duration (7 or 15 seconds) for the composite bonding strength with primary molar dentin towards shear strength.
