Abstract
The present study examined the hypothesis that women with eating disorders associated with a history of chronic vomiting can be characterized by a salivary flora with high levels of aciduric organisms, such as, mutans strepotococci, lactobacilli and yeast. Three groups of female subjects were studied: vomiting bulimics (G1; n = 14), and comparison groups selected for high Streptococcus mutans (G2; n = 13), and low S. mutans levels (G3; n = 12). The prevalence and levels of mutans streptococci, lactobacilli and yeast tended to be higher in bulimics than in non‐bulimics. The bulimics had significantly higher levels and higher prevalence of Streptococcus sobrinus than the non‐bulimics. A high S. sobrinus colonization may be a marker for a history of vomiting in bulimia.
