About the National Data

Data

Data Source:  National Health and Nutrition Examination Survey (NHANES), CDC/NCHS

Baseline: 29.1 percent of adults aged 75 years and over had untreated root surface decay in 2015-16

Target: 20.1 percent

Numerator
Number of adults aged 75 and over with root decay that have not been restored observed in at least 1 tooth.
Denominator
Number of adults aged 75 and over who have at least 1 permanent tooth present and valid codes for root decay on at least 1 tooth.
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were not available for this objective. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline.
