Muhammet Kerim Ayar, Fatih Erdemir
Universal adhesives have been recently introduced for use as self-etch or etch-and-rinse adhesives depending on the dental substrate and clinical condition. However, their bonding effectiveness to laser-irradiated enamel is still not well-known. Thus, the aim of this study was to compare the shear bond strength (SBS) of universal adhesives (Single Bond Universal; Nova Compo-B Plus) applied to Er,Cr:YSGG laser-irradiated enamel with SBS of the same adhesives applied in self-etch and acid-etching modes, respectively...

Presence of diastema between anterior teeth is often considered an onerous esthetic problem. Various treatment modalities are available for diastema closure. However, not all diastemas can be treated the same in terms of modality or timing. The extent and the etiology of the diastema must be properly evaluated. Proper case selection is of paramount importance for a successful treatment. In this case report, diastema closure was performed with direct composite restorations. One bottle etch-and-rinse adhesive was used and a single shade was used to close the diastemas...

Technically important wide band-gap semiconductors such as GaN, AlN, ZnO and SiC are crystallized in polar structures. Taking SiC as an example, we investigate the effect of surface polarity on the wetting behavior by water using experiments and molecular dynamic simulations. It is found that the contact angle (CA) of deionized water on the carbon-face (C-face) is significantly larger than that on the silicon-face (Si-face) for both 6H-SiC and 4H-SiC, while the CA of tetrachloromethane is almost the same on these two faces...
