Caries is the most common oral disease in the United States today, but when preventative measures fail, restorative procedures need to be reliable and long-lasting. Unfortunately, with current techniques, esthetic resin composite restorations have an average lifetime of just six years. At the Division of Biomaterials and Biomechanics, we conduct research to develop new materials to overcome the shortcomings of commercially available products. The main goal of our current project is to reduce the incidence of secondary decay in teeth and improve the longevity of esthetic restorations. The intern in this position will learn techniques involved in biomaterials science as we synthesize and experiment with different formulations of dental adhesives and restorative composites. Specifically, interns will: 1) use organic chemistry methods in the laboratory; 2) master the techniques of monomer and polymer characterization; 3) Use UV-visible spectrophotometry to measure the release rates of various compounds; 4) use a dissecting microscope to count bacterial colonies and cell numbers under a and document them with a digital camera. Females, minorities, first-generation college-bound students, students with a primary language other than English, and students from low income households are strongly encouraged to apply.
