title: Assessing dental caries prevalence in African-American youth and adults.
abstract: It has been well documented that dental caries affect millions of children in the USA with the majority experiencing decay by the late teens. This is especially true for low-income minorities. The objective of this descriptive study was to determine dental caries prevalence in a sample of low-income African-American youth and adults. A total of 1034 individuals were examined. They were divided into two age groups: youth, 9-19 years and adults, 20-39 years. Females comprised approximately 65 percent (64.5) of the study group. The DMFT Index was used to determine caries prevalence in this study population. The DMFT findings showed that approximately 73 percent (72.9 percent) of the youth had either decayed, missing or filled teeth. Male youth had slightly higher DMFT mean scores than female youth: male mean = 7.93, standard error = 0.77, female mean = 7.52, standard error = 0.36; however, as females reached adulthood their DMFT scores increased substantially, mean = 15.18, standard error = 0.36. Caries prevalence was much lower in male adults, DMFT, mean = 7.22, standard error of 0.33. The decayed component for female adults mean score was 6.81, a slight increase over adult males, mean = 6.58. Although there were few filled teeth in both age groups, female adults had slightly more filled teeth than male adults, females mean = 2.91 vs. males; however, adult males experienced slightly more missing teeth, mean = 5.62 as compared to adult females, mean = 5.46. n = 2.20. Both female and male adults had an increase in missing teeth. As age increased there was a significant correlation among decayed, missing and filled teeth as tested by Analysis of Variance (ANOVA), p < 0.01. A significant correlation was found between filled teeth by sex, p < .005. We conclude that caries prevalence was higher in female and male youth, but dental caries increased more rapidly in females as they reached adulthood.
