Research Interests / Professional Overview:

  • Epidemiology of Dental Caries.
  • Prevention of transmission of Mutans Streptococci from mother to infant.
  • Perinatal periodontal health and poor pregnancy outcomes.
  • Dental health services utilization by minorities.
  • Barriers in meeting Healthy People 2010 objectives in relation to dental sealants.
  • Oral Cancer Epidemiology.
  • Mid-level providers in dentistry.


Current Funding:


1R34DE022269-01:  Amy Slep (PI)                         9/23/2001 – 8/29/2013


Planning Parental/Motivational Interventions to Prevent Early Childhood Caries:  This project is the first to employ a time period when couples are maximally open to intervention in the service of oral, physical, and psychological health (i.e., after the birth of a child). It will be the first to intervene with new parents on three hypothesized social determinants of ECC simultaneously: (a) noxious family environments, (b) daily oral health behaviors/promotion for children, and (c) regular, and recommended child dental check-ups.

Role:  Multiple PI
