<p>We investigated the influence of atmosphericpressure lowtemperature plasma treatment on the surface properties of zirconia. After polishing zirconia sections up to #800 with a waterproof abrasive paper, ultrasonic cleaning was performed in acetone and distilled water. Surface treatment was conducted in three groups : nontreated (control), alumina sandblasttreated (Sb), and atmosphericpressure lowtemperature plasmatreated (Ps) groups. The surface properties were examined for surface roughness, scanning electron microscopy (SEM) properties, contact angle, and Xray photoelectron spectroscopy (XPS) properties. No changes in the surface roughness and SEM observations were noted for Ps. Wettability was enhanced by Sb and Ps with respect to the contact angle. Ps showed the lowest contact angle. XPS analysis revealed that Ps remarkably reduced the amount of carbon, allowing removal of contaminants. Atmosphericpressure lowtemperature plasma treatment enables the removal of carbon derived from organic contaminants and improves wettability without increasing the surface roughness of the sample. Therefore,it can be considered a new preadhesion treatment method in clinical dental practice. (J Osaka Dent Univ 2016 ;50 : 79-84) </p>
