title: [Grafting functional groups on enamel surface by a self-assembled monolayer technique].
abstract: OBJECTIVE
  To study the influence of various active groups grafted on the enamel surface by means of self assembly on enamel biomineralization.
  
  
  METHODS
  The enamel was prepared by immersing the bicuspid tooth into 1 mmol/L ethanolic solution of a omega-functionalized (omega=PO4H2, SO3H, COOH or OH) group and deionized water solution of HSCH2CH2SO3Na for 24 h at room temperature. The contact angles and infrared (IR) images were used to identify the morphological changes of the enamel with chemisorption of the functional groups.
  
  
  RESULTS
  The contact angles and IR images showed that the omega-functionalized (omega=-PO4H2, -SO3H, -COOH, -OH or -CH3) group was chemisorbed on the enamel surface.
  
  
  CONCLUSIONS
  Self assembled monolayers with omega-functionalized (omega=-PO4H2, -SO3H, -COOH, -OH or -CH3) group can be successfully formed on the enamel surface by hydrolyzation.
