Second assignment: Possible collaboration with Thammasat University and Khon Kaen University

For Thammasat University, proposed by Community Dentistry Group, Faculty of Dentistry, Thammasat University led by Dr Piya Siriphant (DDS and PhD in Health Education from University of North Carolina, USA) and his team consisted of Dr Sutee Suksudaj (DDS and PhD in Social Epidemiology from University of Adelaide, Australia), Dr Nattira Suksudaj (DDS and PhD in Dental Education from University of Adelaide, Australia), Dr Matana Kettratad (DDS nad PhD in Geriatric Dentistry from University of British Columbia, Canada) and Dr Woranuch Chetpakdeechit (DDS and Odont Dr from University of Goteburg, Sweden). Collaborative International Workshop on the creation of Practice based evidence for the promotion of oral health in a globalized world. This one-week workshop will be organized in Thailand every January. Emphases of this workshop are on 1) theory based health promotion planning, monitoring, evaluation and re-planning; 2) health literacy assessment and applications for the promotion of oral health; 3) community-wide intervention and empowerment; 4) lessons learned from Mai Kin Wan Network (a coalition to promote the reduction of sugar consumption in Thailand) and actions of Thai Health (a special non-government sin-tax fund advocating for health and quality of life). In addition a six-week field practice after the workshop could be granted in one of certified community hospitals in the rural areas of Thailand. The practicum will be co-supervised by experienced local dental professionals and faculty members of Thammasat University School of Dentistry.

For Khon Kean University, the community dentistry group led by Dr Waranuch Pitiphat is willing to accept Niigata University PhD students in global oral Health Sciences for few weeks.


How could experience gain from attending the workshop could benefit or apply to the PhD program at Niigata University?
The same 5-day-course should be offered to all of the PhD candidates in order to expand their knowledge in conducting clinical research in oral health. The course should be organised as an continuing education course for all dentists who wish to conduct a clinical research in oral health which allows the PhD candidates to attend at the same time.

Collaboration with Thammasat University and Khon Kaen University in the extramural externship for PhD students should be trialled in the new future in order to prepare for the new PhD curriculum in Global Oral Health Sciences.
