National Yang-Ming University School of Dentistry Dean Hsu’s post-doctoral research team includes the researcher Wang Ding-Han, who has been awarded the J. Morita Post-Doctoral Competition Award for IADR geriatric oral research by the International Association for Dental Research.


The annual assembly was hosted by the International Association for Dental Research, IADR, which is one of the world’s most renowned international dentistry academic conventions, and has exceptional meaning in the dental field. In 2018, the assembly was held in London, and there were in excess of 110,000 participants, 3,573 research posters and nearly a hundred sessions.

The research team, led by Dean of the School of Dentistry, National Yang-Ming University, Professor Hsu and Associate Professor Lin, have been focusing on the research that targets oral functioning using neuro imaging methods; in particular they have targeted the central nervous mechanisms associated with chewing/swallowing movements. The theme of award-winning research was to investigate the association between individual grey matter volume (GMV) and the frequency of RSST among older adults using a voxel-based morphometry (VBM) approach. Dr Wang pointed out that the act of swallowing is a very complex, but also a sequential muscular movement. Most researchers believe the ability to successfully swallow is correlated to the type of food and the secretion of saliva; as for the central nervous system, especially the link between human brain and swallow related movement, there has been a lack of detailed research. The results collected by Dean Hsu's group indicate that healthy older individuals who have a larger grey matter volume in the posterior cerebellum have a higher swallowing frequency, thus highlighting the cerebellum’s role in motor-cognitive control of voluntary swallowing. The detailed results of this study are currently undergoing rigorous academic peer review. The team hopes that these results will further expand the knowledge in the area of geriatricora research.


Dr. Wang remarked that Taiwan is now an aged society (more than 14% of the population is over 65 years old), and this has led to issues relating to medicine and long-term care becoming more important. As the population quickly ages, oral dysfunction is one of the most important but easily ignored problem for seniors and special needs groups. Patients who have difficulty consuming food, eventually have to be fed by nasogastric tube (NG tube) in order to maintain water and nutrients intake. In Taiwan, the rate of nasogastric tube retention is 2 to 3 times higher than in other countries. Often times when a patient starts nasogastric tube placement, he or she will require the tube forever. In reality, the ability to consume through the mouth is a pride and right of every human being. With this team, through the mechanism mentioned above, they seek to find better clinical treatments for such patients in the future.

During this year’s IADR annual conference, in addition to Researcher Wang’s post-doctoral dissertation award, Taiwan was further honored. This was through Dean Hsu’s efforts and resulted in the privilege of holding this year’s annual IADR symposium. This is a world-class dentistry research conference. In order to hold an IADR symposium, one must successfully invite world-class scholars from at least three or more continents. In order to extend the topic of chewing and swallowing function among the elderly in Taiwan to a world class platform, Dean Hsu has personally invited Prof. Frank Lobbezoo from University of Amsterdam (Europe) , Prof. Limor Avivi-Arber from University of Toronto (North America), Prof. Makoto Inoue from Niigata University (Asia) and Professor Lin from National Yang Ming University (Asia), to help hold this symposium.
