Abstract

Background: to evaluate the effect of different dentifrices on the surface roughness of two composite resins
(nanofilled-based and nanoceramic – based composite resins). Materials and methods: Forty specimens
(diameter 12 mm and height of 2mm) prepared from different composite resin materials: Z350 (nanofilled
composite, and Ceram-X (nanoceramic) .they were subjected to brushing simulation equivalent to the
period of 1 year. The groups assessed were a control group brushed with distilled water (G1), Opalescence
whitening toothpasteR (G2), Colgate sensitive pro-relief (G3) and Biomed Charcoal Toothpaste (G4). The
initial and final roughness of each group was tested by surface roughness tester. The results were statistically
analyzed using ANOVA and Tueky test at 0.05 significance level. Results: the surface roughness of the
two tested composites brushed with the tested dentifrices was statistically higher than the roughness found
in control group. Comparison among the three types of dentifrices showed that there was a statistically
high significant difference in the surface roughness among all subgroups. Charcoal Toothpaste showed the
highest surface roughness increase. Conclusion: Whitening dentifrices increase the surface roughness of
dental composite thereby compromising its durability. Changes in composite depended on the material itself
and the dentifrices used.
