The purpose of this study was to grasp the awareness on dental digital system in dental hygiene students. From September 12, 2015 to November 13, a self-reported questionnaire was carried out targeting 736 juniors and seniors, who have the experience of clinical practice, among 82 universities in which the department of dental hygiene is opened. As a result of analyzing through using SPSS WIN 18.0 program, the following conclusions were obtained. 1. A case of perceiving dental digital system accounted for 52.7%. A case of having the experience of education on dental digital system amounted to 26.8%. The experience of education in class took up 16.4%. The experience of education during clinical practice or dental part-time job comprised 11.0%. The experience of education on internet or at academic society or seminar held 0.3%. The experience of education in mass media accounted for 0.1%. 2. The digital system, which is used in dental hospital and clinic, was the largest in X-ray system with 77.3%. Next, the digital camera amounted to 54.9%. The electronic chart comprised 48.4%. The intra-oral camera took up 40.1%. The software computer system for patient education held 24.3%. The CAD/CAM system occupied 17.5%. The oral scanner formed 16.4%. 3. A case of hoping for education and practice on dental digital procedure accounted for 83.3%. The desired digital education was possessed 49.2% by electronic chart, 26.8% by intra-oral camera, 19.4% by digital camera, 34.5% by CAD/CAM system, 36.3% by digital X-ray system, 34.0% by software computer system for patient education, and 22.0% by oral scanner. 4. In terms of a difference in awareness of introducing dental digital system according to whether or not perceiving dental digital system, a case of recognizing dental digital system, compared to a case of failing to perceive, was high in improvement of dental medical environment(4.15±.639, p<0.001), in a patients' satisfaction level(3.94±.612, p<0.05), and in a recognition of dental digital(3.66±.593, p<0.001), and had a statistically significant difference. 5. As for a difference in awareness of introducing dental digital system depending on educational experience, a case of having the experience of education on dental digital system, compared to a case without educational experience, had high awareness in improvement of dental medical environment(4.25±.594, p<0.001), in a patient's satisfaction level(3.99±.569, p<0.05), and in a perception of dental digital(3.69±.568, p<0.01), and had a statistically significant difference.
