Purpose:
To compare the influence of various surface treatments on the shear bond strength and surface roughness of lithium disilicate glass-ceramics.
Methods:
60 lithium disilicate ceramic samples were prepared according to the manufacturers' instructions and were divided into six groups according to the surface treatment:Control (C), 5% HF etching for 20 and 60 seconds (E20, E60), Monobond Etch & Prime etching (MEP), Nd:YAG (ND) and Er:YAG (ER) laser irradiation. All groups were treated with a universal primer except group MEP. A self-adhesive resin cement was bonded to all groups. The shear bond strengths of the specimens were measured using a universal testing machine while surface roughness was measured using a profilometer.
Results:
Kruskal-Wallis and Mann-Whitney U tests revealed significant differences (P< 0.05). The shear bond strength of group E60 was higher than the other groups while surface roughness of groups MEP and ER were highest.
Clinical Significance:
Monobond Etch & Prime might be a useful method in order to obtain adequate bond strength values.

When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

03:05Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
