OBJECTIVES
Estimate the proportion of amalgam restorations among the US population.
METHODS
Data from ≥15 year old clinically examined dentate participants in three 2-year survey cycles (NHANES 2011-2016) were analyzed. The 2015-2016 data include restorative material type, allowing for the first time a US estimate of amalgam-restored teeth.
RESULTS
The percent of the US population with at least one restoration (65.8 ± 1.4) was relatively constant in 2011-2016. Among those with restored teeth, the mean number of teeth with amalgam restorations increased with age from 4.71 among 15-24 year olds to 7.03 among those ≥75 years. Non-Hispanic Whites with restored teeth had the highest mean of teeth with amalgam restorations (5.94), while non-Hispanic Blacks had the lowest (5.08).
CONCLUSION
In 2015-2016, about half (51.5 percent) of restored teeth in the US population contained amalgam. Amalgam presence varied by age, tooth type, and race/ethnicity, but not by sex. These estimates can be used to assess future US caries prevention and dental amalgam reduction efforts.
目的
估计美国人口中汞合金修复体的比例。
方法
对三项为期两年的调查周期（NHANES 2011-2016）中≥15 岁经临床检查的有齿参与者的数据进行分析。2015-2016 年的数据包括修复材料类型，首次允许对美国的汞合金修复牙进行估计。
结果
2011-2016 年，美国至少有一颗修复体的人口比例（65.8±1.4）相对稳定。在有修复牙的人群中，随着年龄的增长，用汞合金修复的牙齿数量从 15-24 岁人群的平均 4.71 颗增加到≥75 岁人群的 7.03 颗。有修复牙的非西班牙裔白人的用汞合金修复的牙齿平均数最高（5.94），而非西班牙裔黑人的最低（5.08）。
结论
在 2015-2016 年，美国人口中约有一半（51.5%）的修复牙含有汞合金。汞合金的存在因年龄、牙齿类型和种族/民族而异，但与性别无关。这些估计可用于评估未来美国的龋齿预防和牙科汞合金减少工作。
