Effect of Various Etching Techniques on Shear Strength of Newer Generation Composites.

Aim: To evaluate the effect of lasers on the shear bond strength of Giomer and G-aenial flo composite using three different etching techniques.

Materials And Methods: 60 Samples (extracted human premolar teeth) are cut horizontally using a diamond disk to expose a flat occlusal surface involving enamel and dentin. On exposed occlusal surfaces, etching is done by various methods.
