Data Source: 
National Health and Nutrition Examination Survey

Target-Setting Method: 
10 percent improvement

Number of children aged 6 to 9 with a clinical confirmation of dental sealants applied to one or more first permanent molars


Number of children aged 6 to 9 with at least one permanent first molar present and valid sealant codes for at least one permanent first molar

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

    This objective 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. A description of the clinical protocol used to confirm evidence of protective dental sealants has been published by NCHS. The teeth included in the measurement protocol for each age group differ. For ages 3 to 5, primary molars are included – due to eruption patterns, this includes 1st and 2nd primary molars For ages 6 to 9, only first permanent molars are tracked. For ages 13 to 15, both 1st and 2nd permanent molars are tracked, and to be included in the numerator sealants must be present on both a 1st molar and on a 2nd molar.

Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 21-08a in that the age range was revised from "8" to "6 to 9" years.
