Alteration of the hydrophilic property of zirconia disks with smooth and roughened surfaces after UV treatment. A photographic image of 1-μL H2O droplets pipetted onto zirconia disks before and after the application of UV light (left). The histograms show the contact angle of 1-μL H2O droplets measured by an automatic contact angle measuring device before and after UV treatment on different zirconia disks with smooth and roughened surfaces (right).
