Perspectives on a new educational system for dental hygiene students in Japan.

The purpose of this article is to report changes to dental hygiene education in Japan and to evaluate the successful implementation of these changes in 2010. The legislative change that began in 2005 revised the length of education for dental hygiene students from two years to three or four years (the mandate was three years), which has led to a dramatic change in program curriculum. After a five-year moratorium, a new curriculum has been established for dental hygiene education in Japan.
