| Abstract | ||
| The aim of this study was to determine the mean roughness values of the stone casts Surfaces that were poured from two different gypsum products (ZETA and QD) dental stones on the three different impression materials (Supersil,Neogenate and Xanthano). Ten patients were selected to perform this study, for each patient six impressions were recorded. Sixty stone casts were poured and examined to evaluate surface roughness values. The stone casts were tested for surface roughness values with surface-roughness-measuring instrument,Profilometer(Perthometer). The data were statistically analyzed using ANOVA and Duncan's multiple range test. The results of this study showed that there were a significant differences in the mean roughness values of the stone casts among the three different impression materials and two different dental stones used at alevel of (P≤0.05). It was concluded that the smoothest surface of the stone cast were obtained from poured ZETA stone on Supersil impressions, while roughness surface were observed on the stone casts produced from poured QD dental stone on Xanthano impressions. | ||
