Abstract：AIM: To investigate the effects of infiltration resin ICON, flow resin Z350 and fissure sealant 3M on on early enamel caries. METHODS:60 freshly extracted bovine teeth were randomly divided into 4 groups (n=15) after artificial enamel caries had been built. The samples were treated with ICON ( group A), Z350 (group B) and 3M (groups C) respectively, those in Group D received no treatmentad the controls. Enamel surface roughness, micro hardness and percentage of penetration were measured. RESULTS:Enamel roughness value was in the following order;group D>group B>group A> group C, (between each 2 groups, P<0. 05); micro hardness value:group A>group B>group C>group D, (between each 2 groups, P<0. 05); percentage of penetration depth were:group A>group B>group C >group D (between each 2 groups, P <0. 05 except group B vs. group C). CONCLUSION:When applied on artificial enamel lesions, fissure sealant may produce the lowest surface roughness value. ICON may produce the highest micro hardness and percentage of the penetration value.
