The National Maternal and Child Oral Health Resource Center (OHRC) responds to the needs of professionals working in states and communities to improve oral health services for pregnant women, infants, children, and adolescents, including those with special health care needs, and their families. OHRC administers two federally funded projects: (1) the Center for Oral Health Systems Integration and Improvement (COHSII) to improve systems of care for the maternal and child health population, and (2) the National Center for Early Childhood Health and Wellness (NCECHW) to provide education, technical assistance, and training to the Head Start and child care community.
