Abstract
Salivary analyses were made on native-born and native-reared children in 2 regions, Coast and Central, in Oregon. Significant variations were found between counties in pH, buffer capacity, ammonia N, and lactobacillus counts. There was also a consistent significant variation in buffer capacity between the sexes. Significant positive correlations were found between lactobacillus counts and the Snyder test and between pH and buffer capacity. Significant negative correlations were found between lactobacillus counts and ammonia N, and between ammonia N and the Snyder test.
