The New Hampshire 2013-14 Third Grade Healthy Smiles – Healthy Growth Survey was conducted between September 2013 and June 2014. The project goal was to gather uniform data on oral health and the height/weight status of third grade students, which would guide public health program planning, monitoring, evaluation, and future allocation of resources. The New Hampshire Department of Health and Human Services, Division of Public Health Services (DPHS), collected data at the state and county levels. The Nashua Division of Public Health and Community Services joined the project, adding city-level data for Nashua. The HNH Foundation and Northeast Delta Dental Foundation provided survey funding, while the Association of State and Territorial Dental Directors contributed technical assistance for the sampling and data analyses.
