Assessing dental caries prevalence in African-American youth and adults.

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.

Streptococcus mutans levels and caries prevalence in low-income schoolchildren.

Previous studies have shown that persons having high Streptococcus mutans levels in the saliva are "at risk" for dental caries. Most investigators agree, that if high levels of S. mutans were identified early in the life of at-risk children, dental decay could be reduced or eliminated through intervention.
