The purpose of this study is to provide the improvement basis for Dental Hygiene education program by analyzing the current implement status of Dental Hygiene curriculum in Korea and comparing the status with the US ADA standard. The researcher analyzed the Dental Hygiene syllabus limiting "Dental prophxis", "Comprehensive dental hygiene" subjects only from 31 universities which offer 3 years program. The main interest was to figure the implementing status of the curriculum and to compare the actual teaching content with the CODA 2-17 standard. The results show that there are a number of problems in implementing the Dental Hygiene courses among different universities. First, there is a significant inconsistence among schools in terms of course title, total credit, hours, the ratio for theory and practice, etc. In addition, there is a big gap between the actual content of Dental Hygiene courses and the essential/required content of CODA 2-17 standard. For instance, most of the Dental Hygiene programs in Korea cover the overall assessment stage content and some of implementation stage content. However, very few programs deal with the planning and evaluation stage content. To improve these problematic circumstance a number of suggestions were made. Developing the standardized curriculum for the Dental Hygiene program might be one of the major solutions. Next, the regular accreditation and/or assessment system for the Dental Hygiene program should be developed. This research can provide the basis for the need to assess and improve the Dental Hygiene curriculum.
