Introduction
Along with opening of education market in parallel with internationalization, numbers of international students in South Korea has been continuously increased since 2005 [1] . Internalization of universities is considered as an important component for competitiveness and may be beneficial in terms of securing outstanding human resources; it will positively influence future competitiveness of the country hence significantly affecting on national economy as well as industrial development [2] . Universities in South Korea has been putting much effort on recruiting international students for broadening international recognition as well as countermeasures against decline in the number of students; given these situations, it is further expected that numbers of international students in South Korea will be continuously increasing [3] . Previously, it was reported that, due to cultural differences, these Chinese international students are under poor conditions in terms of social aspects as well as health aspects; importantly medical issues often influence on their scholarly performance. Therefore, in the present study, we investigated knowledge and attitude regarding dental health in Chinese international students hence providing preliminary information for dental maintenance and awareness of dental health in international students.
