OH-1.1 Reduce the proportion of children aged 3 to 5 years with dental caries experience in their primary teeth

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Health and Nutrition Examination Survey
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
33.3 (1999-2004)
Target-Setting Method: 
10 percent improvement

Number of children aged 3 to 5 years with coronal caries or presence of fillings observed in at least one primary tooth


Number of children aged 3 to 5 years with at least one primary tooth present and valid coronal caries codes for at least one primary tooth

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Methodology Notes: 

    Caries experience is defined as the presence of either untreated or treated (restored or filled) tooth decay. Caries is the disease that causes tooth decay and can lead to cavities in teeth. This measure is tracked using the Oral Health Examination component of the Continuous National Health and Nutrition Examination Survey, collected since 1999. The measurement protocol described for Healthy People 2000 is still in use. Data on missing primary teeth are not captured by NHANES. Indicators of caries in primary teeth omit missing teeth to avoid potential misclassification of teeth lost to natural exfoliation as missing due to caries.

Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 21-01a in that the age range was revised from "2 to 4" to "3 to 5" years.
