Yasushi Shimada
Tokyo Medical and Dental University, Japan
Professor Yasushi Shimada was educated at Tokyo Medical and Dental University and achieving his DDS in 1987 and PhD in 1992. He was a guest scientist at National Institute of Standards and Technology (NIST) from 1997 to 1999 and at American Dental Association Health Foundation (ADAHF) in 2007. His extended research activities have involved characterization of dental adhesives introducing new methodologies such as the wire-loop micro-shear bond strength test.
Recently, he played a major role of development of dental OCT (Optical Coherence Tomography) system at TMDU in collaboration with dental equipment manufacturer. OCT uses light for taking image, and OCT does not require any X ray radiation dose. So, there is no risk of radiation exposure in OCT, totally safe to use for small children and even for pregnancy women. OCT is capable of imaging dental caries and other dental diseases with high imaging resolution. Enamel demineralization is imaged as white zone in gray scale OCT image with increased brightness. Tooth crack and interfacial gap of adhesive restorations are imaged as bright lines in OCT with high accuracy. Consequently, cavity adaptation of composite restoration can be clearly monitored in OCT.
He was appointed to the Professor and Chair of Department of Cariology and Operative Dentistry of TMDU in 2021. He has supervised over 50 graduate students and postdoctoral researchers from Japan and around the world. -

Doctor Junji Tagami was educated at Tokyo Medical and Dental University (TMDU), achieving his DDS in 1980 and his PhD in 1984, and in 1995, he was appointed to the Professor and Chair of the Department of Cariology and Operative Dentistry at Tokyo Medical and Dental University, and retired at March, 2021. After the retirement, he was awarded the title of Professor Emeritus at TMDU. Currently, he is the director of Aoyama Quartz Dental Clinic, providing international and domestic seminars. He is a prolific author who has contributed more than 600 papers to peer-reviewed international journals and some 200 papers to Japanese academic journals in the fields of cariology, tooth-colored dental restorative systems, the bonding of materials to dental tissues, and dental education.
As the vice president and past dean of TMDU, he could establish the international network with the dental schools in Thailand, China, Taiwan, Indonesia, Vietnam, Myanmar, Malaysia, United Kingdom, France, Germany, Czech, United States of America, Brazil and others. As the chair of Cariology and Operative Dentistrty for 26 years, he has supervised over 190 graduate students and postdoctoral researchers from Japan and around the world in the past 20 years, some of whom have become prominent academicians themselves in Japan, North America, Europe, Asia, South America and Australia. He has also taken international initiative to bring experts together to exchange opinions and advance the field through major events such as the International Congress on Adhesive Dentistry (since 2002).
He is widely recognized as one of the principal driving forces in the modernization of the clinical practice of dentistry through promotion of adhesive dentistry. His contribution to adhesive dentistry will continue to bring significant improvements in the routine practice of dentistry and the dental service provided to the public.
