The aim of this study was to investigate the surface roughness of resin infiltration (RI) on the artificial white spot lesions (WSLs) after being stained with discoloring agents and after brushing.
WSLs were produced on the buccal surface of 48 tooth samples. Each WSL received ICON treatment (RI). The samples were randomly divided into three main groups (n=16): group A, distilled water; group B, tea; group C, coffee. Each group was sub-grouped (n=8) to non-brushing (1) and brushing (2). The specimens were subjected to a discoloring material for one week, then mechanical brushing for subgroups 2 was carried out. The surface roughness was measured at the baseline, after production of WSLs, after resin treatment, after discoloration, and after the brushing stage. Results were analyzed with repeated measure two-way ANOVA and Bonferroni test.
The surface roughness of WSLs decreased with highly significant value after treatment with RI, the roughness of RI was acceptable and there is no statistical difference with baseline stage.
The surface roughness of infiltrated WSLs was acceptable but higher than that at the baseline. Resin infiltration had a highly staining ability that affect the surface roughness but can be significantly reduced by brushing.
