Abstract
Two carbohydrates predominate in modern diets namely sucrose and
starch. They are metabolized by oral microorganisms to products
implicated in dental caries. The influence of sucrose and its
metabolites is well documented but starches have received less
attention. This study investigated the secretion of starch
hydrolysing enzymes by oral streptococci and the production of
sugars, acids and polysaccharides from the two ccmponents of
starch, amylose and amylopectin. ( Abbreviation abstract )
