Dental schools in Japan are among many worldwide whose medium of instruction is not in English. With advances in science, technology, and communication, the demand for the globalization of professions increases. At present, dental schools in Asia, the Middle East, and Europe have started revising their dental curricula to either include English courses for dentistry or offer a full English dental curriculum. In Japan, dental English courses started to be introduced into curricula in the early 1990s. However, a survey conducted in 1999 found that English courses were not offered in Japan's twenty-nine dental schools and there was no consensus as to what such courses should include or when and how they should be taught. Ten years after that survey, the survey results reported in this article found that the problems reported in the 1999 survey still exist. Additionally, there are still differences among schools offering English courses in terms of the timing and contents of the courses. Since teachers and school oficials will have an important role in curriculum development, this article recommends that a fact-inding meeting with educators, school, and education oficials be initiated to discuss, develop, and implement a core curriculum for these dental English courses.
