Adherence of 3 H‐labelled cells of Streptococcus gordonii and Streptococcus milleri to artificial pellicles prepared from saliva supplemented with glucosyltransferases from mutans streptococci was examined using a new assay for sucrose‐dependent cell‐to‐pellicle attachment. Results indicate that S. gordonii , but not S. milleri , could attach tightly to hydroxylapatite surfaces through de novo glucan synthesis by mutans streptococcal glucosyltransferases present in the experimental salivary pellicles.
