“…The factors that influence the wetting of a solid by a liquid include the relative surface free energy of the former and the surface tension of the latter. To achieve optimal wettability, the surface free energy of the solid (γS) must be maximized, and the liquid should exhibit a lower contact angle to the solid [21][22][23] . The surface tension component γS LW can be obtained by solving the complete Young equation 27) , and is due to three distinct interactions: randomly oriented permanent dipole-permanent dipole (orientation) interactions; randomly oriented permanent dipoleinduced dipole (induction) interactions; and fluctuating dipole-induced dipole (dispersion) interactions.…”

“…The surface free energies were determined by measuring the contact angle on the surface for three test liquids, distilled water, 1-bromonaphthalen, and ethylene glycol, each of which has known surface free-energy parameters ( Table 3). The Drop Master DM500 apparatus (Kyowa Interface Science, Saitama, Japan) was fitted with a charge-coupled device (CCD) camera, which allowed automatic measurements of the contact angles to be taken 23) . For each test liquid, the equilibrium contact angle (Ө) was measured using the sessile-drop method at 23±1°C for five specimens of each adhesive.…”

We compared the surface free energies and enamel bond strengths of single-step self-etch adhesives with and without an oxygeninhibited layer. The adhesives were applied to the enamel surfaces of bovine incisors, light irradiated, and the oxygen-inhibited layer was either retained or removed with ethanol. The surface free energies and their components (γS LW , γS + , and γS − ) were determined by measuring the contact angles of three test liquids placed on the cured adhesives. The enamel bond strengths of specimens with and without the oxygen-inhibited layer were measured. For all surfaces, the value of the estimated surface tension component γS LW was relatively constant. The value of the γS + component increased slightly when the oxygen-inhibited layer was removed, whereas that of the γS − component decreased significantly. The enamel bond strengths of the self-etch adhesives were significantly lower in the specimens without an oxygen-inhibited layer. The oxygen-inhibited layer therefore appeared to promote higher enamel bond strength.

In this study, we investigated the influence of light intensity on the surface-free energy and dentin bond strength of single-step selfetch adhesives. The adhesives were applied to the dentin surfaces of bovine mandibular incisors and cured with light intensities of 0 (no irradiation), 200, 400, and 600 mW/cm 2 . Surface-free energies were determined by measuring the contact angles of three test liquids placed on the cured adhesives. Dentin bond strengths of the specimens were also measured. Polymerization with a higher light intensity resulted in a lower surface-free energy of the cured adhesives. The greatest bond strength was achieved when a light intensity of 400 mW/cm 2 or greater was used. Our data suggest that the surface-free energy and dentin bond strength of single-step self-etch adhesives are affected by light intensity of the curing unit.

“…In a previous study, many surfaces had γs d values that were close to 40 mN/m 27) , and other studies attributed these values to adsorption of a socalled "atmospheric contamination layer" 28) , particularly on chemically and/or mechanically activated surfaces 29) . Hence, the presence of this atmospheric layer may explain similarities of γs d values between the present treatment groups.…”

(AB, Bisco) were used in this study. Bovine dentin surfaces were air polished with glycine or sodium bicarbonate powders prior to the bonding procedure, and resin pastes were bonded to the dentin surface using universal adhesives. SBSs were determined after 24-h storage in distilled water at 37°C. Surface-free energy was then determined by measuring contact angles using three test liquids on dentin surfaces. Significantly lower SBSs were observed for dentin that was air-powder polished and surface-free energies were concomitantly lowered. This study indicated that air-powder polishing influences SBSs and surface-free energies. However, glycine powder produced smaller changes in these surface parameters than sodium bicarbonate.
