[Chemical composition (carbohydrates) of dental plaque in different areas of the mouth. 1. Preliminary results].

Abstract

In general differences in plaque composition between anterior and posterior teeth have been reported. Dental plaque from the upper lower anterior teeth shows differences in bacterial composition and pH. Results showed that plaque from lower anterior teeth contained less alkali soluble polysaccharide per unit weight than did plaque from upper anterior teeth. However no differences in the concentration of water soluble and insoluble polysaccharide were observed. Plaque from posterior teeth did not show differences.
