**1. Introduction**

Khon Kaen University (KKU), Thailand has carried out field work to improve the health, including oral health of the population in the northeast of Thailand and other rural areas. KKU has an important mission to produce graduates with essential knowledge, skills and attitudes to be able to help in national development, especially in the northeast of Thailand, and has been actively pursuing this duty and responsibility since 1984.

The KKU field practice course began in 1984 for health sciences students in KKU and the College of Asian Scholars. These students will have direct experience in solving problems in rural areas under the supervision of our staffs in related fields. They gain the experiences of working together with other students for sustainable health development.
