Abstract
Summary
Analysis of supragingival salivary calculus disclosed many similarities in composition to urinary and submaxillary gland calculus.

In addition the supragingival salivary calculus contained small amounts of sialic acid, xylose and arabinose. From the nature of the carbohydrate components it would appear that both saliva and bacteria contribute to the composition of supragingival salivary calculus.
