Abstract：AIM:To investigate the effect of Duraphat,GC tooth mousse and fluoride-containing toothpaste on the remineralization of enamel white spot lesions.METHODS:40 bovine enamel blocks were subjected to surface demineralization (pH 4.5,24 h)to produce artificial white spot lesions.The samples were divided into 4 groups and subjected to the following treatments respectively:immersed in artificial saliva for 12 d (group A),covered with Dura-phat for 12 h,and then after cover removal,immersed in artificial saliva for 12 d (group B),covered with GC tooth mousse for 1m twice daily (8:00am and 8:00pm),then immersed in artificial saliva,repeated for 12 d (group C), immersed in fluoride-containing toothpaste slurry for 3min twice daily (8:00am and 8:00pm),then immersed in arti-ficial saliva,repeated for 12 d(group D).The surface hardness of the blocks was measured before and after treatment and surface microhardness recovery rate (SMHR%)was calculated.The surface of the samples was observed under SEM.RESULTS:SEM observation showed hydroxyapatite crystal on the demineralized enamel suface after treatment in group B,C and D.The SMHR of group A,B,C and D was 20.43 ±5.91,60.55 ±14.05 ,67.69 ±11.74 and 52.82 ± 3.61 respectively.CONCLUSION:The 3 products are able to accelerate the remineralization of enamal white spot le-sions,Duraphat and GC tooth mousse are more effective than fluoride-containing toothpaste.
