determine the extent to which differences are due to small sample sizes as opposed to true differences in disease experience or availability of restorative treatment. Examination results for adolescents show results similar to those for adults, suggesting that these teens and preteens are experiencing an oral health trajectory similar to that experienced by their parents. At all but one site, more than half of adolescents exhibited untreated decay, and DMF scores were high. However, this group also exhibited attention to caries prevention in that an average of six teeth had been sealed. Children also display high levels of caries experience. About half the children had one permanent tooth and one primary tooth with unfilled decay. More than three primary teeth and one permanent tooth had received restorative care. Differences in rates at which permanent teeth had been sealed are evident across sites, ranging from less than one at the site where caries are most prevalent in all age groups, to almost four teeth. Table 4-24 shows a comparison of three caries-related indicators for third grade children among the five sites and recent statewide data for American Indians and Alaska Natives. The proportion of 9- and 10-year-old children (third grader equivalents) from the five sites with caries experience (one or more decayed or filled teeth) was larger than the proportion in the statewide sample. However, the proportion of untreated caries was lower, and a larger proportion of children at the sites had received one or more sealants. This proportion (68%) exceeds the target for children 8 to 15 years old in Healthy People 2010, which are set at 50% (U.S. Department of Health and Human Services, 2000). Table 4-24.
