A 1984 study of dental disease in 534 children (aged 6-15) of migrant farm workers in Colorado found that the prevalence of disease for this population continues to exceed the national and regional average. The mean DMFS was 3.56 with only 23 per cent caries free compared to a regional non-migrant DMFS mean of 2.50 with 44.7 per cent caries free. Results indicate that the children of migrant farm workers should remain a priority in preventive and restorative dental care programs.
1984年，一项针对科罗拉多州534名（6至15岁）流动农场工人子女的牙科疾病研究发现，该人群的疾病患病率持续超过全国和地区平均水平。平均龋失补牙面数（DMFS）为3.56，只有23%无龋齿，而地区非流动人群的DMFS平均值为2.50，无龋齿率为44.7%。结果表明，流动农场工人的子女应继续作为预防性和修复性牙科护理项目的重点对象。
