Aging of Teeth and its Importance to Dental Practice

Dwayne Arola, PhD

Dr. ArolaDr. Arola received his PhD from the University of Washington in Mechanical Engineering. He is currently an associate professor of Material Science and Engineering (MSE) at the University of Washington, and holds adjunct faculty appointments in Mechanical Engineering, Oral Health Sciences and Restorative Dentistry. His research is broadly focused on the microstructure and mechanical properties of engineered and natural structural materials, with primary focus on their durability, which includes their resistance to fatigue and fracture.  His research relevant to dentistry has been supported by the National Institute of Dental and Craniofacial Research, the National Science Foundation, the American Association for Endodontics Foundation and the Colgate-Palmolive Foundation among others.


Mouthguards and the Orthodontic Patient

Douglas S. Ramsay, DMD, PhD, MSD

Dr. RamsayDouglas Ramsay received a BA in psychology from Franklin & Marshall College in 1979 and a DMD from the University of Pennsylvania in 1983. He came to the UW in 1983 as a senior fellow and in 1985 entered the UW’s NIH-funded Dentist-Scientist Training Program, which supported his doctoral studies in psychology (PhD, 1988) and specialty training in orthodontics (MSD, 1990). He joined the UW faculty in 1990 and is currently Chair of the Department of Oral Health Sciences.  Dr. Ramsay is a professor of Orthodontics, Oral Health Sciences and Pediatric Dentistry.  In addition to numerous NIH research grants, he was the recipient of a Research Career Development Award from the National Institute of Dental and Craniofacial Research.  Dr. Ramsay is a Diplomate of the American Board of Orthodontics and Director of the UW’s Regional Clinical Dental Research Center.


New Optical Dental Care – From Caries Prediction to Therapy Monitoring

Eric Seibel, PhD

Dr. SeibelEric J. Seibel is a Research Professor in the Department of Mechanical Engineering with appointments in Electrical & Computer Engineering, Bioengineering, and Oral Health Sciences at the University of Washington.  He received his BS and MS degrees in Mechanical Engineering from Cornell University and University of California Berkeley, respectively.  After working in the medical device industry for four years, Dr. Seibel received his PhD in Bioengineering from the University of Washington in 1996.  His research interests are bringing new opto-mechanical biomedical devices from bench to bedside, such as the scanning fiber endoscope.  He is director of the Human Photonics Lab as is PI of the NSF grant entitled, “Smart Laser-Based Imaging and Optical Spectroscopy System: optical quantification of bacterial load, oral health surveillance, and caries prediction.”
