The University of Iowa College of Dentistry , in collaboration with the Virtual Hospital. Major Research Programs at the College of Dentistry Research at at the College of Dentistry reflects the complex nature of today's health care needs. The scientific basis of dentistry encompasses the diverse tissue systems of the oral cavity and its associated orofacial structures. Many different approaches are employed, ranging from cell culture and molecular biology to the exploration of new treatment modalities. Although research is organized into several major programs, a strength of the College of Dentistry has been the consistent level of interaction and collaboration among individuals and across program boundaries.
Many projects transcend areas of specialization and are strengthened by shared expertise.
Wefel, Drake, and others. Research on dental caries explores factors responsible for destruction of tooth enamel as well as methods for preventing the disease. Changes in the demographic structure of our society and the increasing number of individuals who retain their teeth into old age has increased the importance of studies of lesions occurring on root surfaces exposed by recession of gingival tissues. Investigations are under way to characterize bacteriological and immunological factors important in caries development. The use of fluoride to prevent lesion development or to remineralize existing lesions continues to be explored as well as the use of fluoride restorative materials.
