| 520 | _aOur study aims to compare between remineralization and sealingstrategies of white spot lesion by evaluating the effect of sealing techniques using resin infiltration systemor remineralization usingnano-hydroxyapatite paste versus their combination on surface roughness and micro-hardness of initial enamel carious lesion. A total number of 276reading out of 35 sound human premolars were usedin this study, the teeth were sectioned to remove the root, then the halves were sectioned again using the same cutting disc in a bucco-lingual direction into mesial and distal halves then embedded in acrylic resin in a teflon mold with the enamel surface uncovered after that the specimens were soaked in a demineralizing solution for 72 hours to induce caries like lesion then the specimens were randomly divided into 2 main equal groups according to assessment method used as follow; first group will be subjected to micro-hardness testing and the second group were tested for surface roughness, each main group was divided into three subgroups according to the type of material tested with 23 specimens in each group after that each subgroup was assessed according pH cycling application and without pH cycling | ||
