This study evaluated the surface changes such as surface average roughness(RA), surface free energy(SFE) and wear depth among groups treated with surface penetrating sealant(Fortify, Biscover), non treated polishing group before and after tooth-brushing, analyzing the influence of the sealants in filling of surface microdefects formed during the finishing and polishing procedures of composite resin.
Results were as follow(p= 0.05) :
1. Ra was increased Biscover. Fortify and Polishing group. Before abrasion and in 6 months, all groups were statistically significant. In 1 month, 2 months and 3 months no statistical difference was noticed between Fortify and Biscover.
2. SFE of Polishig and Biscover group. Fortify and Biscover group were statistically significant before abrasion. SFE of Polishing and Fortify group was statistically significant in 1 month. No statistical difference was noticed among groups in 2 months. SFE of Fortify and Biscover group was statistically significant in 3 months. Polishing and Fortify group, Fortify and Biscover group were statistically significant in 6 months.
3, Wear rate between Polishing and Fortify group was statistically significant in only 1 month. Wear rate between Polishing and Biscover group was statistically different in each month except for 2 month and so it was between Fortify and Biscover group. Considering film thickness of Fortify and Biscover, Fortify almost discappeared after 2 months and Biscover did after 6 months.
