title: [Effect of para-aminobenzoic acid on the adhesion of Streptococcus mutans].
abstract: OBJECTIVE
  To investigate the effects of Para-aminobenzoic acid (PABA) on the adhesion of Streptococcus mutans to saliva-coated hydroxyapatite (S-HA).
  
  
  METHODS
  The adhesion model in vitro established by Gibbons was adopted in this study to quantify adsorptive cells through [3H] thymidine labelling.
  
  
  RESULTS
  PABA solution over a range of concentration from 10(-9) to 10(-3) g/L could inhibit the attachment of S. mutans to S-HA effectively, and the inhibition declined when the concentration of PABA solution was 10(-3) g/L.
  
  
  CONCLUSIONS
  PABA can inhibit the adherence of Streptococcus mutans to S-HA effectively.
