| 1. During the lecture it was stated that NHANES did not use radiographs during data collection. What effect might the lack of radiographs have had on disease estimates? In other words, did NHANES likely underestimate or overestimate “true” disease rates because radiographs were not taken? |

| 3. The total mean DMFT values for adults (ages 20-64 years) declined between 1988-1994 and 1999-2004. What effect did this overall decline have on the relative contribution of “decayed” teeth to the mean DMFT? In other words, during which period were adults relatively more likely to have untreated decay? |
|
Definition
| Adults were relatively more likely to have untreated decay during 1999-2004 because overall DMFT was lower and the decayed (D) component remained the same |
