- Abstract
Objective To screen of high cariogenicity Streptococcus mutans (S. mutans) strains isolated from clinical specimens preliminary. Methods Acidogenicity, aciduricity, extracellular polysaccharicle production and adhesion of 41 strains of S. mutans isolated from clinical specimens were investigated to screen high cariogenicity S. mutans strains. Results There were different cariogenicity among 41 strains of S. mutans, in which 3 strains of S. mutans had all high ability to produce extracellular polyaaccharide, adhere to the saliva-coated hydroxyapatite, produce acid and tolerate acid, indicated there were 3 strains with high cariogenicity S. mutans strains isolated from clinical specimens. Another 3 strains of S. mutans with all low ability to produce extracellular polysaccharide, adhere to the saliva-coated hydroxyapatite, produce acid and tolerate acid indicated they were low cariogenicity S. mutans strains isolated from clinical specimens. Conclusion We may have obtained high cariogenicity S. mutans strains isolated from clinical specimens.
