Dr. Emi Shimizu is an Assistant Professor in the Department of Oral Biology. She received her D.D.S in Biology in 1998 from the Nihon University School of Dentistry at Matsudo in Japan. A Ph.D. in Endodontics from the Graduate School of Nihon University was received in 2002. She also enrolled Advanced Education Programs in Endodontics in New York University College of Dentistry and finished in 2012. Dr. Shimizu worked as an Assistant Professor in Department of Basic Science and Craniofacial Biology in New York University College of Dentistry and identified interaction of ephrin-Eph plays an important role in tertiary dentin formation using various mouse models. In December 2016, she joined the Department of Oral Biology at Rutgers School Dental Medicine.
The dental pulp nourishes dentin, serves as a biosensor, contains a dental pulp stem cell population, and plays significant roles in tooth viability. Currently, the most common strategy to treat injured dental pulp (due to caries, restorative procedures, or trauma) is its removal, and substitution by synthetic materials. Indeed, advancements in dental research have increased our abilities to maintain pulpless teeth for prolonged periods of time. Nonetheless, pulpless teeth, without nutrition supply, innervation, and vascularization, becomes vulnerable to injury, lose the ability to sense environmental changes, and increase the risk for caries progression. In cases of improper endodontic restoration the teeth are more vulnerable to masticatory forces, may fracture, and have to be removed. Therefore, it is widely accepted that maintaining a vital pulp has many benefits. Dr. Shimizu laboratory is studying the physiological mechanisms regulating tertiary dentin following tooth injury using several mouse models. She is also working on tooth regeneration using iPS cells or oral stem cells.
