Dr. Levy's research includes various aspects of oral epidemiology. His research with an extensive team of collaborators on the Iowa Fluoride Study (IFS) is investigating the epidemiology of fluoride intake and dental fluorosis; fluoride intake, dietary patterns, and dental caries; esthetic perceptions of dental fluorosis and other conditions; the relationship between infants' and young children's feeding and sucking patterns and dental growth as well as development and malocclusion. Genetic aspects are now being studied concerning dental fluorosis and caries, with expansion to malocclusion recently began. The bone growth portion of the IFS is called the Iowa Bone Development Study and it also looks at dietary, genetic and physical activity as determinants of bone development in adolescents. Dr. Levy is also part of the interdisciplinary collegiate team involved in early childhood caries prevention. A major study of early childhood caries (ECC) risk assessment that he is a PI has just been initiated. Other current and recent research projects include health services research concerning the use of water fluoride assay and dietary fluoride supplements, the use of dentifrice by preschool children and the effect of dentifrice flavor, and the validity of, and change in, patient medical histories. His past research projects also include the importance of medication use in dentistry, the measurement and prevention of incipient root surface caries, Alzheimer's disease and oral health, and the epidemiology of oral disease among the elderly, including periodontal disease and factors related to tooth loss.
