Purpose Comparatively assess the effect of smokeless tobaccosalivary substitute mixture on altering surface roughness of amalgam, composite resin, and resin modified glassionomer RMGI restorations. Materials and Methods Sixty cubic restorations three groups of twenty were fabricated using a 4mmx3mmTeflon mold. One examiner assessed the restorations at time points representing zero days, one day, one week, two weeks, one month, and three months. The data obtained were collected using a surface profilometer, measured in micrometers. Data were statistically analyzed using two-way Analysis of Variance ANOVA Test. A difference was significant if p0.05.
