| Abstract | ||
| Aims: The study intended to inspect the consequence of the addition of zirconium oxide (ZrO2) nanoparticle at two concentrations (1% and 1.5% by weight) on the surface roughness of the maxillofacial silicone material (room temperature vulcanized). Materials and methods: Thirty samples were prepared according to the manufacture instructions and divided into three groups (n=10). A digital surface roughness profilometer tested the surface roughness samples for the control group (A) free from nanoparticle, group (B) 1% ZrO2, group (C) 1.5 % ZrO2. Results: The mean values of the surface roughness measured groups a highly significant difference among groups. Group A (.2137 µm) exhibited a highly significant difference compared to group B (.2698 µm) and group C (.2801 µm). Besides, a highly significant difference between group B and group C. Conclusions: Incorporation of 1% and 1.5% by weight of ZrO2 nanoparticle into maxillofacial silicone material increases surface roughness. | ||
