Abstract：AIM:To evaluate the effects of an infiltrating resin and a fluorinated foam on incipient enamel demineralization .METHODS:75 freshly extracted human premolars were made into artificial incipient enamel demi -neralization models .They were randomly divided into 3 groups ( n=25 ) and were treated with deionized water ( group A), fluorinated foam(group B) and infiltrating resin(group C) respectively.Then they were immersed in artificial sa-liva for 8 weeks at 37 ℃.L value of each tooth was measured immediately, 4 weeks and 8 weeks after treatments by a spectrophotometer.Enamel surface was observed under scanning electron microscope (SEM) 4 weeks after treatment. RESULTS:The L value of all teeth decreased after treatment, the degree of △L value was in the following order:C>B>A.The L value was significantly different between groups at 4 and 8 weeks (P<0.05) except between group A and B immediately after treatments .SEM observation showed that the samples in group C had smooth and homogenous enamel surface, while enamel surface was rough and uneven with hollows and mineral deposits in group A and B .CONCLU-SION:Both infiltrating resin and fluorinated foam have remineralizing effects on demineralized enamel surface, but the former is more effective in a short time.
